The rather popular Protherm brand has long taken a firm position as a reliable manufacturer of heating equipment in Russia. In everything model range boilers powered by electricity, one series is presented - Proterm Skat. Protherm electric boilers are produced in 8 modifications with power from 6 to 28 kW with the possibility of smooth power control. Designed for operation in closed heating systems with forced circulation of the coolant. Boilers are installed on the wall, and all connections are made at the bottom of the boiler. Coefficient useful action is 99.5%, which is a very high figure, even among electric boilers. The entire series of skat boilers is single-circuit, and the implementation of hot water supply is carried out by installing an indirect heating boiler.
Most of these disadvantages and advantages are inherent in most boilers powered by electricity.
Advantages of Protherm Skat boilers
- High efficiency
- Easy to install
- Unpretentious in service
- eco friendly
- Doesn't require a lot of space
- Silent operation
Disadvantages of Skat series boilers
- The high cost of electricity
- Dependence on power outages
Sometimes electric boilers are credited with shortcomings that have not been relevant for a long time or were obviously wrong, consider some of them:
Boiler power is not enough to heat a house over 300 m2
This statement is incorrect, due to the fact that Skat boilers can be connected to a cascade to increase the heated area, with a shortage of 28 kW.
Frequent replacement of heating element
Due to the fact that the heat carrier is heated using a heating element, many people believe that such a heating element will not last much, but you need to take into account the quality of the heating element itself and do not forget that it is not water that circulates in the system, but the coolant.
Installation of Proterm Skat boilers in a cascade
If a 28 kW boiler is not enough to heat the house, it is possible to install Skates in a cascade to increase the coverage of the heating area.
When two boilers are connected in a cascade, the second boiler is controlled by a room thermostat, which is connected to the first boiler.
This diagram will look like this:
The contacts of the room thermostat are connected to terminals 1 and 2 located on the K8 connector of the main boiler, and the main boiler terminals 9 and 10 are connected to terminals 1 and 2 of the slave boiler.
In cascade mode, only the Proterm Skat 28 kW boiler and Proterm Skat 24 kW boiler are capable of operating.

Depending on the model of the boiler, the number of power steps varies. The widest control range is available for skat boilers operating from a single-phase network and having a power of 6 and 9 kW.
Guarantee
The warranty period for these boilers is 2 years.
A heating element
Depending on the power of the boiler, a different number of heating elements are installed in them; in the R13 modifications, heating elements were installed in accordance with the following table:
Work from the network 220V and 380V
Boilers with a power of 6 kW and 9 kW, capable of operating from a network of 220V and 380V, boilers of higher power can only be connected to three-phase network 380 volts.
Accessories for boilers Proterm Skat
When buying a boiler, in addition to it, the manufacturer offers various accessories to expand the functionality.
Temperature controllers
For Skat boilers, Proterm suggests using three types of room regulators:
Exabasic (article 6195) , Exacontrol (article 0020159367) and Exacontrol 7 (article 0020170571) .
The simplest Exabasic model has only a rotary switch for setting the temperature, Exacontrol is already equipped with a display and has a mechanical control. Modification number 7 - has the function of weekly programming.
Scheme of connecting the thermostat to the Protherm Skat boiler Temperature sensors
To adjust the operation of the boiler, relative to the temperature outside the window, you should purchase an outdoor temperature sensor (article 0020040797).
Outside temperature sensor for boilers Protherm SKAT In the retail network, its cost varies around 2000 rubles (38 euros).
Installation of the Proterm Skat boiler with a boiler
If you want to secure your home also hot water, then you need to purchase an indirect heating boiler. In order for the boiler to start working in conjunction with the boiler, you need to purchase a Fugas three-way valve kit (article 0020015570) for. The finished kit will cost 116 euros.

Pump
Manufacturer - Wilo
Power - 230V / 50 Hz
Number of speed steps - 2
1st stage, rpm - 2500
2nd stage, rpm - 2600
Before filling and commissioning the Proterm Skat electric boiler, the following steps must be taken:
Loosen the pump air valve cap.
Loosen and unscrew the rotor shaft cover and use a flathead screwdriver to turn the shaft.
If a fairly noticeable resistance is felt during the rotation of the shaft, it is necessary to dismantle the motor part of the pump.
After that, clean the whole stator or rotor of the pump from impurities.
Before removal Wilo pump you need to make sure that the following conditions have been met:
The water temperature in the boiler unit has reached a safe value (40°C).
The boiler has been switched off by the main switch.
Heating water inlets and outlets were closed.
The remaining water was drained from the boiler.
Dismantling of the Wilo pump:
Disconnect the connection cable connecting the pump to the control board.
Remove the heating water pipe leading from the pump to the heat exchanger.
Disconnect the tube leading to the expansion tank.
Pull out the safety clip.
Loosen and unscrew the pump safety screws located at the bottom of the boiler.
Turn the pump slightly clockwise to remove it.
Safety valve
If the maximum allowable pressure in the Proterm Skat boiler is exceeded, excess water will be drained through the safety valve. Valve actuation pressure - 3 bar. The outlet of the safety valve must be equipped with a suitable drain.
If it is necessary to remove the safety valve, proceed as follows:
Wait until the water has cooled down to around 40°C.
Disconnect the Skat Protherm boiler from electrical network.
Close all valves located under the boiler installation.
Disconnect the drain tube from the safety valve.
Drain water from the boiler system using the drain valve.
Remove the safety valve retainer.
Heating water temperature sensors
Temperature sensors - If replacement is necessary, remove the sensor together with the retainer and pull out both two connectors.
Emergency thermostat - 100 °C causes the boiler to stop working - error code F20 (unlock manually). The emergency thermostat for the heating circuit is located at the water outlet of the boiler heat exchanger.
To replace it, unscrew the screws located on the thermostat holder, remove the thermostat together with the holder and disconnect both connectors.
Pressure meter
The pressure sensor is used to determine the water pressure in the boiler (heating system). In the event of a shortage of RH in the boiler, the pressure sensor will transmit information to the control board, which will give a command to stop it.
With an increase in water pressure, the volume of the membrane that carries the magnet will increase. Opposite the magnet is a Gall sensor that changes the input voltage on the Proterm Skat boiler control board depending on changes in the magnetic field parameters. The change in the parameters of the magnetic field depends on the change in the distance of the Gall sensor in relation to the position of the magnet.
Before removing the pressure sensor, it is necessary to close the heating water supply and then drain the water from the unit using the drain valve. Pull slightly to remove the pressure sensor connector. Using a flathead screwdriver, pry out the pressure sensor safety clamp. Remove the pressure sensor by pulling it towards you.
Dismantling the heat exchanger of the heating water circuit
Works on dismantling the heat exchanger:
Remove the front cover, side panels and top cover of the boiler unit.
Disconnect the wires of the heating elements from the Skat Protherm electric boiler control board and the terminal box and disconnect the grounding conductor.
Disconnect the heating water supply pipe at the bottom of the heat exchanger.
Remove the heating water outlet pipe at the top of the heat exchanger.
Loosen and then unscrew the bolts located at the top.
By slightly pulling upwards, pull the heat exchanger out of the boiler.
Removing the heating coils
Dismantling operations:
Remove the front panel of the boiler and its top or bottom cover (depending on which element needs to be replaced).
Disconnect the wires of the appropriate heating element from the control board and terminal block, as well as the ground conductor.
Unscrew the heating element from the heat exchanger housing with a wrench of the appropriate size in a counterclockwise direction.
Expansion tank
The expansion tank is used to equalize the pressure of heating water, the volume of which increases when heated. The expansion tank of the Proterm Skat electric boiler is designed for a maximum amount of water in the heating system - 90 liters (at a temperature of 75 ° C). The expansion tank is located at the rear of the unit.
Before filling the heating system with water, check the pressure in the expansion tank. The initial pressure in it should be 0.2 bar more than the static height of the water column in the heating system.
Fill the heating system with water. The filling pressure must be 0.2 - 0.3 bar higher than the water pressure in the expansion tank. The water pressure when filling the system is checked on the pressure gauge on the water supply side, cold and after venting the system.
The valve for filling the expansion tank is located in its upper part. If water flows out of the filling valve of the expansion tank, this means that its membrane is damaged. In this case, the expansion tank must be replaced.
Expansion tank removal:
Loosen and unscrew the screws located at the top of the boiler frame.
Loosen and unscrew the nut of the inlet pipe leading to the expansion tank.
Pull upwards to remove the expansion tank.
At reverse installation it is necessary to give new sealing gaskets.
Skat Protherm electric boilers do not have their own bypass, so it is recommended to install it directly in heating systems.
The boiler connections must not be subjected to stress from the pipes of the heating system. To do this, it is necessary to accurately observe the dimensions of the ends of all connected pipes both in height and in relation to distances from the wall and the relative position of the individual inputs and outputs in relation to each other.
It is recommended to connect the electric boiler to the heating system in such a way that, if the boiler needs to be repaired, the heating water can only be drained from it. During reconstruction, unfavorable planning, etc. the boiler can be connected to the heating system using flexible hoses designed exclusively for this purpose.
The flexible hoses used must be as short as possible, protected from mechanical and chemical influences, as well as from damage. Before the end of the service life or in case of loss of the ability to reliably perform their functions, the used flexible hoses must be replaced.
new.
The electric boiler Proterm Skat can be used to heat water entering the underfloor heating system. In this case, it is necessary to connect an emergency thermostat for underfloor heating systems (not included in the scope of supply) to the boiler.
Emergency thermostat for water temperature control in systems floor heating connected to the boiler power terminal block. Boiler systems are usually equipped with a factory-installed jumper that closes the terminals for connecting an emergency thermostat for underfloor heating systems. Before connecting the thermostat, the jumper must be removed.
The heating system, according to the indications of the boiler devices, must be filled with water at least until it reaches a hydraulic pressure of 1 bar (which corresponds to the hydrostatic height of a 10-meter water column).
If a room thermostat is installed in the reference room, it is necessary that at least one of the heating coils located there does not have a thermostatic valve installed.
To increase the thermal comfort in the room where the room thermostat is located, we recommend that you do not install thermostatic heads on radiators at all.
Before installing a new Skat Protherm boiler, the heating system must be thoroughly cleaned. Before the boiler, namely on the return heating water pipeline, it is recommended to install a sump. The sump must be constructed in such a way that it can be cleaned regularly without
the need to drain a large amount of heating water.
A sump can be combined with a filter, but a filter with a sieve alone is not sufficient protection. Both the filter and the sump must be checked and cleaned regularly.
Works on the installation of the electric boiler Proterm Skat:
The mechanical structure of the boiler unit with the pump and accessories is hung on the rail.
The cover can be removed and fixed to the rear wall with screws.
To install the boiler, it is necessary to choose a place that will allow carrying out service operations without major obstacles.
If the boiler is installed in an open system, the water level of the heating system must create a pressure of 1 bar.
In heating systems equipped with thermostatic valves, the water circulation can be completely closed, in which case it is necessary to install a bypass pipe that is not equipped with a thermostatic valve or use a bypass.
When installing the front panel, make sure that the plastic frame sits exactly in place, and that a grounding pad is placed under each screw that fixes the front panel.
Electrical connection of the boiler Proterm Skat
Electric boilers Skat Protherm are designed for permanent connection to fixed electrical wiring. It must be equipped with a disconnecting device - a main switch, in which the distance between open contacts is at least 3 mm for all poles, provided that the instructions for commissioning are followed.
Before installing the boiler, the user is obliged to ensure that a separate power wiring is laid, including the main switch of the heating system, fuses, as well as to carry out other necessary changes in the internal wiring.
In the case when it is not possible to connect to a three-phase electrical network, Proterm Skat boilers with a power range of 6 and 9 kW can also be connected to a single-phase one. To do this, use the connecting bridge supplied with the boiler.
With the help of a connecting bridge, the contacts of the phase wires are mutually connected on the terminal block designed to supply the supply voltage to the unit.

Equipment automation
Automation and instrumentation are designed to monitor and prevent emergencies during the operation of Proterm boiler equipment.
The function of equithermal temperature measurement allows you to save energy consumption depending on weather conditions: on warm days, the boiler operates at minimum power, on cold days - at maximum load.
Electronics Composition:
- Safety valve (to prevent overpressure in the system).
Anti-jamming device. - RCD. Protects people and animals from leakage currents when touching the case of a faulty device.
- Load regulator relay. When connected to a household electrical appliance network, the relay automatically gradually lowers the boiler power. When the network is normalized, the automation brings the device to normal operation.
- Temperature relay. When the temperature in the room drops to 8 degrees, the pump starts. An air temperature sensor must be connected for this function to work.
- The control panel is equipped with the function of storing parameters and setting the boiler output. For medium models with several heating elements, it is possible to work in operating modes with reduced load.
- Installation must be carried out in accordance with the attached instructions for each model. Protherm recommends using the services of a professional service, as in this case, the service and repair warranty will apply.
Important! When mounting the equipment on your own, damage to the case is frequent, which can lead to a violation of warranty obligations by the consumer.
- The installation site must be carefully considered: the boilers must be easily accessible for inspection and maintenance. Measuring devices must be in a conspicuous place.
- If a forced circulation circuit is used, the boiler must be installed at the highest point of the heating system.
- When mounting several boilers in a room, a parallel connection must be used.
- The cable cross-section, the power of circuit breakers and RCDs must be selected taking into account the power of the boiler and circulation pump.
- In the house, it is necessary to carry out grounding of the TN-C-S or TN-S type, the heating system devices must be grounded.
For correct operation of the device, it is necessary to configure it correctly:

Question: I recently noticed that the voltage stabilizer clicks after that the boiler starts to work unstably, what could it be?
Answer: It's not about the boiler. The stabilizer clicks because the relay is activated when the voltage drops in the network, it breaks the phase for a short time - this is why the boiler may not behave stably from a phase break.
Question: There is a Protherm KLZ 50 gas boiler with a turbo nozzle. A problem arose - a stain appeared on the firebox, and it is gradually increasing all the time. They called local specialists, they said that usually no one dealt with such problems.
After a few more calls, a specialist (chief engineer) finally arrived and adjusted the gas supply on the boiler - after that, the boiler began to work with modulation (that is, first at low speed and then at full speed). Before that, it always turned on at full power and threshed without stopping in cold weather. It was during the heating season of 2013 and the spot stopped growing. This year, the whole spot began to grow again. What to do?
Answer: If the burner insulation is not damaged, the stain will not affect the safe operation of the equipment.
Question: Maybe the boiler cycles often and consumes a lot of gas due to the fact that the boiler power is too high? I have S=220m2, power=38 kW. I took such power with the prospect of heating the garage. If so, what should I do to stabilize the boiler and gas consumption?
Answer: Definitely. We need to reduce the power. Not at a minimum, but proportionally.
Question: Tell me: I'm planning a cheetah 25 boiler who and bkn proterm B100Z. Whether additional three-way valves and pumps are needed.
Answer: The three-way valve and the pump are already built into the boiler. All you need is a boiler sensor.
Question: what does a two-stage burner mean in relation to Grizzly 65 KLO: is it the notorious winter-summer mode (i.e. 1 stage - summer, second stage - winter) or minimum (1 stage) and maximum (2 stage) of boiler operation, which are normally it is set to the maximum at the factory, there is no official information on the site, as well as in the manual.
Answer: A 2-stage burner is an analogue of modulation, i.e. the boiler can operate at maximum power (stage 2), it can operate at reduced power (stage 1) or turn off if there is no demand for heat at all. Moreover, both steps are configurable.
Question: if the house is well insulated, then it is possible that a 30 kW boiler will also cycle. What does it have to do with when cold power is needed one, warmer another, the temperature changes during the day by 10-15 degrees, from 0 to -15, etc. How then to be? Provided that any boiler cannot be regulated by yourself, but call a specialist. Explain how to behave with this boiler?
Answer: if the house is well insulated, the probability of clocking is reduced. The house cools down more slowly, the coolant in the heating system also cools less, the boiler sees this and does not work at maximum power, but modulates only to maintain it.
Choose a boiler with maximum power that will cover the maximum heat demand of your home. You don’t need to take a large stock (unless you plan to expand). Further, the boiler will modulate, depending on the need - it became warmer outside, the power decreases, colder - increases.
Question: A Protherm 30 KLOM floor standing boiler has been installed. The heating project is still under development, combined heating is supposed: radiators and underfloor heating. According to the instructions for the boiler, the power supply of the circulation pump must be connected not directly to the socket, but through the boiler terminals so that the boiler can turn off the pump at low temperatures and, as I understand it, in this regard, prevent corrosion of cast iron. But for a warm floor, it is supposed to use a warm floor with a mixing unit and another circulation pump. When the main heating pump is turned off, the floor heating pump can still circulate through the boiler if it is connected directly to the socket.
In this regard, 2 groups of questions:
1) It turns out that for the safety of the boiler it is necessary to hang both pumps on the boiler terminals? But in the instructions, I did not find explanations on this matter and the maximum power of the connected equipment. Is this possible, what is the maximum power and is it possible to see some link to
document allowing it?
2) In addition, ideally, I would like to connect the power supply of the floor heating pump through the thermostat installed in the room (turns on the power supply 220V when the temperature decreases and turns off when the temperature rises), to automate the regulation of the floor temperature. It turns out that this is basically impossible?
Answer: You cannot connect two pumps to one terminal. Proterm does not have such a control scheme. To control the TP there is a cascade automation. SD2000 is out of production.
Question: I can not find the data on the pump power for this boiler, can you help? For example, if we have one pump with a head of 4 meters, then it consumes 45 W, if 6 meters, then it consumes 80 W, if one pump is 8 meters, then it consumes 170 W. So why is it not possible to connect 2-3 pumps of 45-80 W each? What is the reason for this?
Answer: This is due to the fact that the manufacturer provides for the connection to the terminals of only one pump. Connecting 2x or more is at your own peril and risk.
Question: for connecting the B200S boiler to the Medved KLOM 30 gas floor-standing boiler. The manual for the B200S says: To ensure the operation of the boiler with the PROTHERM boiler, an electromechanical three-way valve with a built-in electric
changeover contact size DN ?” (for use with wall-mounted boilers) or DN 1” (for use with floor standing cast iron boilers).
The manual for KLOM says: The boiler control system regulates the heating of the boiler using a pump and an NTC sensor of the boiler. Nothing is said about the three-way valve. It is not entirely clear which scheme is preferable? Which electromechanical isolating three-way valve with integrated electrical changeover contact do you mean? Where can I see its specifications? The principle of controlling the circulation pump is not yet clear, does the boiler turn off the pump or change its performance?
Answer: These are two possible schemes for connecting the boiler to KLOM - through a three-way and through pumps. In the first case, pumps are not needed, except for the circulation pump, in the second - a three-way one.
Question: Proterm skat - is it possible to work painlessly from a generator according to single-phase circuit inclusions?
Answer: Models 6K and 9K can operate from the mains voltage of both ~ 380V and ~ 220V, others only from ~ 380V.
Question: Is it correct to connect the floor-standing boiler Medved KLZ 30 through a hydraulic separator to separate heating circuits (Conventionally 2 circuits, respectively tied to automatic temperature control). I ask other things - in KLZ the heating circuit of the built-in boiler is already integrated and, logically, when the boiler pump is turned on, the boiler circuit pump will be turned off.
Accordingly, there is no circulation - the secondary circuits will work for themselves, that is, drive the cooled coolant until the boiler pump turns off and the boiler pump turns on. Or no
bother and put KLOM 30 and connect the boiler to the hydraulic gun as a third circuit? Who will advise what?
Answer: Protherm does not have such recommended schemes, but it does not prohibit them. That is, they have the right to exist. This is about correctness. As for the schemes. I believe that it can be done this way and that, there are two nuances: In the first scheme, if you forget to close the hot water tap, the heating system will cool down and freeze in cold weather. In the second scheme, this will not happen. Boiler room dimensions. The second option requires more space.
Question: I installed the Skat 21 kW electric boiler, in the process of studying the Installation and Operation Instructions for the boiler, I found information that there should be a minimum distance to the ceiling above the boiler - 800 mm. What is the reason for this, why such a gap? I did not find such a requirement in the Instructions for the gas boiler. Is this specific to the electric boiler? In fact, I get about 400 mm. Is this a big problem?
Answer: 800 mm is required to replace the heating element, if you have 400 mm, then you will have to remove the boiler to replace the heating element, this will not affect the operation of the boiler.
Question: We have a Panther 25 kV boiler connected, a specialist launched it a week ago. I woke up in the morning, the error message f68 is on, there is no such error in the book, what should I do? I'm trying to reset the reset error, the boiler starts up to a temperature of 32 and gives an error.
Answer: The problem is the loss of the flame. That is, either the boiler does not see the flame (see towards the ionization electrodes), or there really is no flame (see towards the gas - supply or gas valve).
Question: The problem is, there is a Protherm KLOM 50 with a turbo nozzle that has worked for 1.5 years, does not start. When turned on, the turbo nozzle starts up, the display shows the current temperature of the coolant and the indicator flickers on the right in the corner and that's it! What's this?
Answer: It is possible that the turbocharger manostat is stuck. If the atmospheric pressure is abnormally low, decrease the sensitivity.
Question: For a house S = 100 m2, which floor or wall boiler is better? taking into account the connection of a warm floor in two rooms S = 16 AND 18 M2 AND THREE points of water analysis. my choice fell on proterm but which one exactly I don't know tell me please?
Answer: Approximate power for your house is about 15 kW. More precisely you will be told in the design organization. As for the models - the main difference between wall-mounted and floor-standing boilers, of course, are the dimensions and installation options. They have different variants compatibility with thermostats. Mounted have more control options. It is also important to decide whether a double-circuit boiler or a combination of a single-circuit boiler + boiler.
Question: Proterm KLOM 40 boiler and turbo nozzle installed. I have been operating the boiler since December 2013 ... I controlled the operation of the boiler in the morning and evening. in March he moved into the house and noticed a feature. from time to time the boiler accelerates to 85 degrees at a set temperature of 60 degrees. moreover, when the boiler accelerates to 85 degrees, the lower right mark flashes on the screen and the circulation pump does not vibrate (I determine the operation of the pump connected to the boiler by placing my hand on it, otherwise you will not hear it). after heating the boiler to 85, the pump turns on and the boiler goes into normal mode ... it cools down to 55, warms up to 65. What could be?
Answer: the diode is blinking - the boiler is operating in the mode of heating water in the boiler. Everything is in order - this is the bacteria protection program in the boiler - short-term heating.
Question: how to determine the frequency of short-term heating? I read that when the water in the boiler is parsed in bursts, the boiler gives the command to stop the pump for heating and, as a priority, heats the water in the boiler (boiler for 200 liters) and after heating the water in the boiler to the nominal value, turns the pump back on to the batteries and since the boiler is in the error does not go away, which means that the boiler automation does not find violations. There are only two buttons on the boiler, and what a smart one it turned out to be.
Answer: This boiler does not have a bacteria protection function in the boiler. This heats up the boiler. Regardless of the analysis of water, when there is a request for heating water in the boiler, the boiler switches to heating the boiler at maximum power, which is why the temperature rises to 85. Heating
not active at the moment. As soon as the heating of the boiler is finished, the boiler switches to heating. DHW is a priority.
Question: What is the difference (except power) between the Cheetah 23 MTV and Panther 25 KTV boilers? The sellers said that there are more copper parts in the Panther (Cheetah is a cheaper Panther). So I want to understand what are the fundamental design differences in order to decide whether it is worth overpaying. What are their heat exchangers made of? in the event of a temporary shutdown of gas and / or electricity, both boilers turn on automatically?
Answer: Structurally - different expansion tanks of 5 and 7 liters. Plus, the difference in the design of the front panel. they are partly right, since the Panther is more powerful and has a larger heat exchanger. But in general, they are the same. in the event of a power cut / turn on - the boilers will turn on, if gas - both are in error, switching on after resetting the error.
Question: It is necessary to connect only BKN to the 30 KLOM outdoor speaker. This boiler will only work to load the boiler. Accordingly, the entire system consists of a boiler, BKN, a safety group, a membrane tank and a circulation pump. How to do it right? Is it just to connect a temperature sensor and a boiler loading pump to the block, or are there any nuances?
Answer: It is necessary to transfer the boiler to " summer mode"for heating, then it will only work for the boiler. There are no other nuances.
Question: Tell me, the boiler is installed Protherm Cheetah, at low burner power, error 28 or 29 pops up. And it still does not maintain the set temperature (it does not turn off after the set temperature is reached). Where to look, what to turn?
Answer: Your boiler probably has problems with the gas valve. Here I can only recommend an examination by a specialist.
Question: They installed a bear klz 40 boiler for me. It started normally, no one lives in the house yet, but left the boiler on. After 2 days I arrived, the boiler with the error F1 is standing. I reset the error, it starts, but at different intervals it throws f1 again. Could it be from
due to insufficient ventilation?
Or dig towards electricity? The voltage seems to be stable, but in any case I will
put ups. And the second question is which gsm module is better to put on my proterm to control the boiler via SMS? Is it possible to reset errors via SMS? The phases are observed, the hot water boiler is not filled and not turned on.
Answer: This error means blocking the automatic ignition and stopping the gas supply through the gas valve, i.e. loss of flame. Such a blockage can occur in cases where, being in the open gas valve mode, the automatic ignition does not receive a return signal about the presence of a flame from the ionization electrode.
This malfunction can also be caused by the operation of the emergency thermostat or the flue gas thermostat. Low inlet gas pressure, incorrect electrical connection (phase and zero reversed) can also cause flame loss. If the fault cannot be cleared with the RESET button, contact your service organization. Regarding GSM - Proterm does not have such modules.
Question: It turns out that the modulation should work and the boiler will maintain a stable temperature from a water flow of 3 l / min? We will observe in practice. Well, it is clear that with a clogged heat exchanger there will be no normal heat transfer and water flow. We are talking about how the new boiler should work and whether there are gas adjustments for hot water supply, that is, the ability to reduce the power of the hot water supply so that the boiler does not cycle with low pressure in the water supply.
Answer: After switching on, the modulation should maintain a stable temperature. There are no gas regulation for DHW. Automation itself regulates the operation of gas fittings.
Question: The SO10045 sensor for connecting a boiler is a thermal resistance. The thermostat performs a similar function. Why is a sensor needed to connect the boiler and boiler?
Answer: the principle of operation is similar, but when operating from a thermostat, the boiler does not receive information from the boiler about the water temperature, therefore it does not have the ability to modulate the heating power, but only turns on at full power and turns off, which is not economical. Plus, when using SO10045, the current temperature in the boiler is displayed on the boiler - conveniently and clearly.

Questions to Proterm representatives
Question: Gas floor boiler proterm. It is necessary to remake 85 clo with connecting the boiler through a three-way valve to connecting the boiler through a pump. I understand that replacing the board solves everything, but still?
Answer: Initially, the boiler must be connected to the 85th KLO through a pump. See wiring diagram. PLO is connected through the boiler.
Question: A floor double-circuit boiler Protherm Medved KLOM 40 and a turbo nozzle were installed. The instructions for the boiler indicate that when connecting the turbo nozzle, it is necessary to bridge the terminals of the flue gas thermostat. This thermostat, as I understand it, is installed under the chimney. How to bridge it and is it necessary to do it? The specialist launched the device, but he didn’t even remember for this sensor. Which room regulator should be connected? Any or there is some kind of trick. Is there a regulator this model with two pairs of contacts?
Question: Proterm Skat. There is a scheme for the operation of this boiler for hot water supply through a three-way and an NTS sensor. For example, I have a 9-12 kW electric boiler, I need only 6 kW for heating. I have it, of course, the soul from the settings panel to the required. But when switching to DHW heating, how much will it consume? Are the power settings for both DHW and heating saved? Is it possible to supply, for example, also 6 kW for DHW heating?
Answer: DHW power is not adjustable (always full power). Your DHW does not work all the time. And at higher power, the boiler will heat the water faster. What is more economical, longer to heat with a weak device or faster with a powerful one, you have to look.
Question: which burner is suitable for the Proterm Bizon 35 NL boiler to operate on liquefied gas, or how much does it cost to reconfigure regular gas. burners for LPG? And in general, what bad / good can you tell about this model, or recommend something else, since you decided to take a closer look at the floor cast iron boilers. It is necessary to reconfigure the BTG 3 burner for liquefied gas or put it in, let it down
pipeline from a gas tank or cylinder and does it work?
Answer: No. This burner must have a valve suitable sizes to obtain the correct ignition and smooth adjustment. The valves are sized for a supply pressure of approximately 300 mm HC. I recommend checking the burner gas pressure with a water pressure gauge.
Question: I launched the Skat electric boiler, I was just about to buy Instat-2, but it was removed, it turns out to be out of production. What do you recommend in return?
Answer: take a look at Termolink S and SD 2000.
Question: I choose a double-circuit boiler. I settled on Panther 25 KTV or turboTEC pro VUW (mini version). Questions arose: As far as I understand, the DHW COMFORT function in Panther is an analogue of a hot start in Plus. But if the Plus has two additional sensors for hot water, then the Panther does not have them. How is the temperature maintained in the secondary heat exchanger of this unit?
Answer: Hot start function. Principle of operation: The burner turns on when the temperature in the primary circuit drops by 30 °C below the set DHW temperature. The burner switches off when the temperature reaches a difference of 10 °C below the set DHW temperature. The ECO symbol will appear on the display when the set DHW temperature is below 50°C.
Question: I have a double-circuit wall-mounted gas boiler Proterm Pantera with a bottled gas burner. On cold start there is a strong hum. As the antifreeze warms up, the buzz goes away completely. What could be the reason?
Answer: Cold and hot antifreeze have different characteristics. Thus, while the antifreeze is cold, a buzz can be observed.
Question: could you tell me - I have a PROTHERM B200S boiler with a magnesium electrode, they started installing it, a question arose. At the very top of the tank there is a valve with a diameter, if I'm not mistaken, 3/4 plastic with a thread, about 5 cm long, marked as RC (recirculation) in the instructions. What is it for, what is connected to it?
Answer: This branch pipe is connected to the DHW line - DHW recirculation.
Question: what is the specifics of connecting the Proterm B100S boiler to the non-volatile boiler TLO bear? The water in the boiler coil, apparently, moves forcibly, and the heating system is implied with the EC, are these completely independent cycles?
Answer: if you connect the boiler according to the scheme with a feed pump, the boiler ceases to be non-volatile, the board changes, pumps are added. If through a 3-way valve - one pump will be needed, again, the system ceases to be non-volatile.
Question: The Proterm Rys gas boiler has been operating since 2008. What is the service life of such a unit and is it possible to connect an indirect heating boiler to it?
Answer: Under the operating conditions indicated by the manufacturer - about 10 years (again, the manufacturer indicates). Protherm does not provide for the possibility of connecting the BKN to the Lynx. If you decide to try - at your own risk.
Question: what is the difference between wall-mounted boilers Proterm Gepard 23 MTV, Panther 25 KTV, Tiger 24 KTZ?
Answer: The Panther is a little more powerful than the Cheetah (both in terms of heating and hot water supply) + it has a different control panel. The tiger has a built-in 45 liter storage boiler, which increases maximum flow DHW.
Question: I am faced with the choice of a gas boiler. You need heating and hot water. The house is about 165 squares. Tell me by proterm what suits me? And another question - are there boilers with a side discharge, that is, you don’t need to make a huge chimney and the discharge occurs immediately sideways through the wall? Do you have any? Another question - do I need to install a boiler? What does he give? And another point - it happens that they turn off the electricity - will all this work without it, or does everyone need electricity?
Answer: In terms of power and water intake, gas, wall-mounted, double-circuit (heating + hot water supply), electrically dependent, with a closed combustion chamber are suitable for you (it is possible to remove combustion components to the side through the wall). Boilers Gepard 23 MTV, Panther 25 KTV, Tiger 24 KTZ, gas, floor-standing, with combustion, a boiler is additionally required for hot water. Bear 30 TLO - electrically independent. Bears 30 PLO/KLOM/KLZ -
electrically dependent, it is possible to install (additionally) the "Semi-turbo" extension, which will make it possible to divert the combustion components to the side through the wall, but it is powered by electricity.
Question: Boiler KLZ 30 Proterm Medved. Strange work from an outdoor temperature sensor. T - 55 gr. C, curve - E5, the lower the air temperature, the hotter it becomes at home, and vice versa, the closer to zero, the colder. So the temperature in the house jumps (with one setting mode) from 22 gr. C to 30. You have to constantly "play" with the temperature or the curve. Is it possible to transfer this boiler to home wireless sensors?
Answer: In the equithermal regulation mode, the temperature of the heat carrier in the boiler is regulated depending on the change in the outside air temperature. Therefore, you can only "play" here with a curve. According to sensors - there are no wireless controllers in the Russian Protherm catalog.
Question: the KLZ 30 Medved boiler was installed in March last year, it worked well, now when the air temperature drops, the temperature is added to 80 degrees, the boiler goes out. gives error F1. works normally up to 70 gr, and when t increases, it goes out. I've tried turning the throttle dial, but it doesn't help.
Answer: Try using the RESET button to reset the error, if the problem remains, you need to call the service, since you need to look for a problem in the operation of the ionization electrode, gas valve, etc.
Question: what is the reason for the limitation on the volume of coolant in the heating system when using a wall-mounted gas boiler Protherm Lynx (70 liters)? If the system is assembled from steel pipes and cast-iron radiators (works flawlessly for several years) on an area of 180 sq. m., obviously with an excess of the maximum volume of the coolant, then what problems should we expect?
Answer: This is due to the capacity of the expansion tank in the boiler (5 liters).
Question: what kind of regulator can be connected to the Panther 25 KTO, the problem is that the boiler heats CO + warm floors (connected through a thermostat with a separate pump), now I took Protherm Instat Plus for testing, when it turns off the boiler, the pump drives over the warm floors cold water. I want the temperature of the coolant in the boiler to drop by 5 degrees at night, the temperature in the house will drop and the warm floor will not cool down.
Answer: Protherm Instat Plus will do the job for you. (Programmable controller with weekly and daily program allows you to set up to 6 different time intervals during one day. In these time intervals you can set any temperature from the allowable temperature range). Thermolink Lux will also be able to adjust by day of the week and time periods.
Question: I need to not turn off the boiler, but reduce the temperature of the coolant in the boiler: example: from 65 to 61 at night, Thermolink Lux can do this, or as simply as Protherm Instat Plus off. boiler at the set temperature in the room?
Answer: Thermolink Lux is connected via eBus, it will regulate the power of the boiler.
Question: In the operating manual for an indirect heating boiler, it is indicated that the tap water in it is heated by heating water. How can it be used to prepare hot water this boiler in the summer, when the heating will be turned off? Where it is necessary to place such a boiler: in the boiler room (five meters of the DHW route) or in the immediate vicinity of the water points (toilet) so that there is no
DHW interruption? Is the second option technically possible?
Answer: If everything is correctly designed and installed, the water will be heated in the summer without heating. it does not matter where to install, in any case, there are options to organize the supply of hot water without interruption.
Question: In the passport for the Panther double-circuit boiler, the maximum temperature in the heating circuit is 85 g, but only 75 g is set on the boiler. what is the reason? How to raise it lo 85 gr, and then when it's cold outside, then the temperature in the house is above 18 gr. does not rise.
Answer: Panther has a maximum temperature of 80 gr. Set by parameter d. 71.
Question: Thermostat contacts are dry contacts? According to the documentation, the thermostat is 3-pin, i.e. can be used as NO and NC contacts?
Answer: Yes, you can.
Question: It is not clear about connecting the boiler to the network to ensure corrosion protection. In the description in Fig. 2, which shows the contacts of the thermostat?
Answer: You just need to connect the boiler to the network, there is a board inside, an anode is connected to it.
Question: The manual mentions a magnesium anode. As I understand it, it needs to be changed at some point. How it's done? Is there a minimum distance between the ceiling and the boiler when mounting on the wall?
Answer: The power anode does not need to be changed. The distance between the ceiling and the boiler is not regulated.
Question: Tell me what determines the value of the minimum gas pressure on the nozzles of 1.1 mbar. on a gas boiler panther 25 ktv 19v? Why is it not recommended to set a lower value?
Answer: At a pressure of 1.1 mbar, the boiler will give out the passport value of the minimum power, therefore, nowhere lower.
Question: tell me the Protherm 30 KLOM gas boiler is phase-independent?
Answer: The boiler is designed to be connected to a single-phase three-wire electrical network 220 V 50 Hz with a protective conductor in accordance with the current PUE. It is not allowed to interchange the wires "phase" (L - brown wire) and "zero" (N - blue wire). Connecting the boiler to the electrical network is an intervention in the internal structure of the apparatus. This work should only be carried out by a specialist.
Question: I have Proterm 30 KLOM. Tell me, how critical is the loss of voltage in the network for his brain? Are there sensors at the boiler that will turn it off in the absence of mains voltage? How does overheating protection work? If critical, how is it customary to fight?
Answer: The overheating protection function turns on the heating pump when the temperature of the water in the heating system exceeds the value set by the user or if the temperature of the heating medium in the boiler exceeds 85°C. If the temperature of the heat carrier in the boiler exceeds 90°C (fault F3), the boiler switches off automatically. In the event of a power outage, the machine will turn off. When the power supply is restored, the boiler will automatically turn on, without losing the set operating parameters. If a fault message appears on the appliance display after the power supply is restored, unblock the boiler using the RESET button. The blocking of the boiler can occur due to its overheating as a result of stopping the pump after.
Question: The Proterm boiler has been in operation since October 2013. The installation of the boiler, heating and water supply systems was carried out by local specialists. The heating system consists of 5 (40 sections) and a PVC pipe d = 25mm with a length of approximately 40 m. I will try to describe the heating system: the boiler is installed on the 1st floor, a horizontal section of the pipe is laid from it to the second floor, from this "riser" two horizontal sections are divorced: on the 1st and 2nd floors, on the 1st floor there are 2 radiators of 8 sections, on the 2nd floor there are 3 radiators of 6, 8 and 10 sections.
The water supply system consists of:
Pumping station - supplies water from a well (pressure on / off, respectively, 1 / 3.5 atm.);
- coarse filter;
- pvc pipe d \u003d 25 mm divorced around the house (length about 10 m).
Problems with heating appeared 2 months after the start of the system, during this time the boiler heated both heating and water. (if it was installed at 60 degrees, it warmed up to 65-68 degrees and turned off, turned on at 52-56 degrees, and now it is set to 75 degrees, and the temperature does not rise above 62 degrees; with water interruption - it will heat up, and after it gets cold for a while). After installing those service has not yet taken place.
Answer: You need to look towards the hydraulics of the system, gas supply. And these things require a specialist.
Question: And how do the brains of the Proterm boiler react to a temporary power outage?
Answer: It shouldn't, it just turns on and that's it. May show an error - RESET is reset. If, in addition to turning off, there are also jumps (without a stabilizer), then the board may be damaged.
Question: The boiler does not work according to the timer. And how does the DHW saving mode turn on on the timer?
Answer: It is necessary to check whether the DHW temperature sensor is installed correctly and works correctly. Check resistance. Replace sensor if necessary. In addition, check the functioning of the electronic board, DHW pump, etc.
Question: tell me, wall-mounted boiler cheetah 23 turbo, underfloor heating system, area 80 squares, plus one cast iron radiator(5 sections) in the boiler room. The temperature on the boiler is set to 60 degrees. Everything was fine. But a week ago, he stopped heating up to the set temperature - 54-55 and that's it. I sinned for a temperature of 30 on the street, but today it was 20 in the afternoon, and he never caught up to 60. Plus, the hot water supply began to work, somehow it’s not right - hot flows for 5 minutes, and then warm, although the device is working. What happened?
Answer: Perhaps there was a drop in the inlet gas pressure and the unit stopped working out the passport characteristics. It is necessary to check the boiler settings, the condition of the hydraulics, etc. Such phenomena must be diagnosed on the spot.
Question: I have a Proterm Medved 40 KLOM boiler, the heating pump is connected directly to the electrical network, is this correct? and can I connect it directly to the boiler and what will it give me?
Answer: Connecting the heating pump to a separate machine may be due to local circumstances and the hydraulic circuit of the furnace. It would be more correct to connect the pump to the boiler so that the circulation of the coolant through the heat exchanger is controlled by the automatics of the boiler and the device does not go into overheating.
If it is not possible to connect to the gas network, and solid fuel heating is not available, then an electric boiler becomes an alternative way to provide heat to the house. This article will introduce readers to the Proterm Skat electric boilers, as well as instruct them on how to launch them.
Electric boilers Proterm Skat
This single-circuit equipment is made in a wall-mounted variation. It is possible to connect a water heater. Most models three-phase mains connection required, but models with a power of 6 kW and 9 kW can be operated from a 220 V network. The choice of the required level of temperature for hot water and heating occurs using the display, which, when adjusted, helps to control the operation of the equipment. Also, control is carried out using a thermostat or an outside temperature sensor.
To create a certain level of warmth, the parameters are adjusted individually. Power supply is controlled remotely from the tariff meter. For domestic needs, you can install units of 24 kW and 28 kW in a cascade.
Protherm Skat has:
- double-sided pump;
- expansion tank;
- safety valve;
Also, the Protherm boiler can be connected through a voltage stabilizer. Electric boiler in action has a slow start, that is, for two minutes it "accelerates" and its power is minimal. Heating elements are protected from overload, their work is uniform, this is achieved by the possibility of setting the rhythm (1.2 or 2.3 kW).
Protherm Skat electric boilers are distinguished by their low weight (only 34 kg) and convenient dimensions, which makes it possible to install on almost any area. The operation of the boiler is reliably protected by several functions:
- pump blocking protection;
- a pressure sensor that monitors the level of water pressure;
- frost protection;
- protection against valve blocking and freezing of the water heater (when connecting a boiler).
If errors occur in the operation of the boiler, automatic diagnostics occur, ending with the display of the results in the form of a code. The deciphering of the codes is given in the instruction manual for the product.
Advantages and disadvantages of Protherm Skat electric boilers
Proterm Skat has a number of advantages over other types of heating:
- does not carry out harmful emissions into the atmosphere, since has no combustion products, so this type of heating can be called environmentally friendly;
- an electric boiler is an affordable type of heating. It is used where it is not possible to connect to the mains gas or can become an alternative form of heating;
- does not need systematic maintenance, unlike, for example, gas or solid fuel models;
- silent operation;
- there is a heat level regulator;
- able to adapt to domestic water of poor quality;
- resistant to voltage drops;
- equipped with several types of protection.
Along with the advantages, there are some disadvantages:
- electric boiler Protherm Skat needs to be connected through a stabilizer;
- not able to perform its work when the mains power is turned off.
Consumer reviews
Consumers note that Protherm Skat provided an opportunity where it was problematic or even impossible to connect gas. With the stable operation of the power grid, many refuse to connect gas, saving considerable amounts of money. In addition, the electric boiler is used in parallel with the gas unit, connecting them to a single heating system. This find allows significant savings on resources, alternating them with each other during the heating season.
If you connect a water heater to Protherm Skat, consumers will have the prospect of using hot water. Many note the perfectly designed design of the boiler, which fits well into any interior of the room. You can successfully install it in living rooms, thanks to silent operation, it will not cause increased attention to itself.
The disadvantages are that when using only a boiler powered by electricity, when it is turned off, there is no alternatives heating. Therefore, before making a purchase of a Protherm electric boiler, you should make sure that there are no problems with electricity. Experts recommend use a voltage stabilizer, to ensure the normal operation of the Protherm Skat boiler.
In addition, increased energy consumption by the electric boiler causes negative emotions the population, as the payment of bills hits the pocket. If we compare the costs of gas and electric heating, then the Protherm electric boiler costs a little more, with identical heating parameters. From the foregoing, we can conclude that this electrical equipment is chosen by those who do not have the ability to connect to the network gas, as well as those who care about the environment and see it as a source of environmental consumption.
How to put the Protherm Skat boiler into action?
To start the boiler, follow the instructions below.
When the pressure is reduced, the “bar” light starts flashing on the display. To correct the situation, water should be added to the system. If in this case the pressure decreases, then you need to contact a specialist.
If you want to stop the operation of the Protherm boiler for a long time, then you need to disconnect it from the power supply and turn off the taps. If you need a stop at winter period, then water must be drained from the system to prevent freezing.
How to take care of the Protherm electric boiler? Do not use abrasive or chemical substances. Better surface wipe the housings with a damp cloth, then dry the surface.
Any malfunctions are shown on the display with an error code. Code numbers are located and deciphered in the product passport.
If serious problems occur, such as the heat exchanger is frozen or water is dripping from it, it is forbidden to turn on the electric boiler to the power supply. It is necessary to wait for a specialist who will diagnose and make a quality repair. Parts can only be replaced with original spare parts.
So, dear readers, you have met alternative view heating Protherm Skat. When gas and solid fuels are out of reach or you are an adherent of cleanliness, an electric boiler can be a good help.
