The device and principle of operation of Proterm boilers
Let us consider in more detail the most popular models of the manufacturer Protherm.
Proterm Gepard 23 MTV (MTV)
This model of a wall-mounted double-circuit boiler belongs to the middle price segment. Equipped with the function of heating liquid for household needs, the power of the device is 23 kW. There are two modifications of the model on the market, natural (MOV) and forced (MTV) removal of the combustion product.
It is possible to control the operation of the boiler using a room thermostat or an outdoor temperature sensor. The design provides for a liquid crystal display, with the help of which the operation of the device is monitored.
Cheetah 23 MTV does not need to be connected to a chimney system, since it has a coaxial smoke exhaust system, which makes it possible to install it in a room without a chimney. The built-in heat exchanger is made of stainless steel, a sensor is provided that controls the pressure in the system.
Works in two modes winter/summer, power adjustment happens thanks to a modulating torch. Water reaches the set temperature after 3 seconds after opening the tap, the efficiency is 91%.
The function of protection against freezing and overheating of the system is provided. Of the benefits - it is very easy to operate, does not pollute the environment during operation, affordable price.
Proterm Lynx
The installation method is wall-mounted, the boiler is designed for space heating and hot liquid heating. Depending on the area of the room, there are two power options 24 kW and 28 kW. Due to the forced removal of combustion products, there is the possibility of installation in a room without an equipped chimney, or if it is not technically possible to equip it there.
Boiler Proterm Lynx
Despite the low cost, it has a good efficiency of 94%, while fuel consumption is low. It has two modes of operation: economical and comfortable. Thanks to the built-in electronics, automatic ignition occurs, and the burning of the flame is also controlled.
Water heating temperature control is carried out using an NTC sensor, which is installed at the outlet of the secondary heat exchanger. Equipped with a three-stage circulation pump, frost protection is provided when the temperature drops below 5 degrees.
Proterm Skat
Model range 6 kW, 9 kW, 12 kW, 18 kW, electric boiler, has the ability to step power adjustment, runs very quietly, suitable for heating small areas.
Boiler Proterm Skat
The device is single-circuit, designed for space heating, the efficiency is 98%, it is connected to a 220 V network. Due to the large number of functions, there is an excellent possibility of remote control.
Proterm Bear 40 KLOM
This is the most popular model in this line of cast iron gas boilers, just like the Proterm KLOM 20, 30,40,50 models. This model is often used together with a solid fuel boiler as an additional heating device.
Boiler Proterm Medved 40 KLOM
A definite plus is ease of use, high efficiency of 92%. Also in the Medved series there is a Proterm 40 KLZ line, which is equipped with a built-in 90 l boiler, it is possible to replace individual cast-iron sections, which significantly reduces the costs associated with repairs.
Proterm Panther (Panthera)
Designed for heating offices, houses and providing hot water. Modifications with an open combustion chamber or sealed are possible. The throughput of hot water is 13-15 liters, the maximum heated area of \u200b\u200bthe room is up to 260 square meters.
It can work with low pressure, the presence of frost protection of the heating system, has a high degree of safety. Thanks to the display, it is possible to monitor the operation of the boiler.
Boiler Proterm Panther
The design provides for two heat exchangers, one for providing heat in the heating system, the other for hot water. Suitable for systems where it is necessary to maintain a minimum temperature, there is a “comfort” mode, when it is turned on, hot liquid flows from the tap after 2 seconds. There is a self-diagnosis system.
Proterm Jaguar
It belongs to the most inexpensive models of wall-mounted gas boilers, designed for an apartment or residential building. There are two options for power 11 and 24 kW, throughput 10 liters per minute, automatic flame modulation, independent operation of two circuits.

Basic error codes
f1
Error F1 (f1). Loss of flame, ignition blocked and gas supply to the gas valve cut off. This happens when the board does not receive a signal about the presence of a flame from the ionization electrode, while the gas valve is open, the protective mechanism is activated and the boiler is turned off.
It could also be due to insufficient gas pressure. To eliminate, press the restart button, and check if the gas valve is open, and it will be useful to check the plug in the socket, turn it over, changing the polarity.
Also, often the error F01 indicates an overheating of the thermostat, to eliminate it, try pressing the restart button on it. This problem very often occurs in the Proterm KLOM model.
f2
Error f2 (f2). The temperature sensor of the heating circuit has failed, or the temperature of the coolant has dropped below 3 degrees. The appliance is locked out because ice may form. Often this indicates a failure of the sensor, check it and, if necessary, replace it with a new one.
Heating circuit temperature sensor
However, this situation can be caused by starting the device in the winter season, when there is really insufficient temperature in the system. To start the system, raise the temperature in the system.
f3
Error f3 (f3). This error indicates that the boiler has overheated and means that the permissible critical maximum of 95 degrees has been reached, the protection is activated and the boiler automatically turns off.
Wait until the temperature drops below this indicator, the boiler will start on its own. If this situation occurs again, reset the thermal fuse.
f4
Error f4. The DHW sensor is out of order, when this breakdown occurs, the boiler normally works to heat the heating circuit, and the heating of the liquid for domestic needs stops. Often, such a breakdown indicates either that the sensor is out of order and needs to be replaced, or the contacts are oxidized, clean and inspect them.
f5
Error f5. Damage to the external temperature sensor. With such a malfunction, the device works, but the temperature control is carried out by the boiler temperature sensor. To eliminate, check if there is a mechanical break in the boiler-sensor circuit, if there is no break, it needs to be replaced.
Boiler temperature sensor Proterm
f6
Error f6 (f6). Indicates a break in the exhaust gas sensor. Ring the connecting wires between the sensor and the board. Perhaps the board is out of order, take it to a service center for diagnostics, or the sensor itself is faulty. This breakdown can be caused by a faulty ignition transformer, check it.
f7
Error f7. The instructions describe the error as a disconnect. This gap can be anywhere, and means that when connected to the controller, a signal does not come from one of the elements, or there is not enough voltage at the terminal on the control board.
It is necessary to visually inspect all the wires, ring them for a break, check all the connectors. It is also possible that the board itself has failed and needs to be repaired. If nothing can be found, seek qualified help from a specialist.
f8
Error f8 Indicates the opening of the NTC sensor circuit and the grounding of the DHW boiler. Ring this chain of connections, disconnect and reconnect these elements, as the contacts may have come off. If these manipulations do not work, replace the sensor.
f10
Error f10. Indicates a short circuit of the NTC temperature sensor on the supply line.
This fault appears on the display if:
- Happened short circuit in NTC device installed at the input of the OF. In this situation, it needs a complete replacement.
- Also possible if the voltage level in the circuit has decreased up to 0.40 V.
- A short circuit has occurred in the device plug. What to do in this situation? Only its complete replacement, it is not subject to repair.
f15
Error f15. Short circuit of the reverse thrust sensor. The combustion products controller is located at the top of the boiler, it is connected to the fan pipes.
It is necessary to disassemble, clean all the terminals, remove deposited formations from the tube. If this procedure does not bring results, a replacement with a new device will be required.
f20
Error f20 (f20). The safety temperature limiter has tripped. It is possible that the supply line temperature sensor is connected incorrectly, because of this the temperature has risen above the permissible norm (95 degrees) or an open circuit has occurred.
Temperature limiter for gas boiler
Call her, if you do not find a malfunction, try reconnecting it. Check if the pump is working, bleed air. If you have not been able to solve this problem yourself, seek help from a specialist.
f22
Error 22. This problem indicates a low fluid pressure in the heating circuit of less than 0.3 bar.
Possible reasons for this:
- Fluid pressure sensor failure. Need to be replaced.
- Malfunction or blockage of the pump, or its work is not adjusted. Clean it out and check for proper operation.
Add fluid to the system. Check all elements for leaks, as pressure may drop due to a leak, if it is found, eliminate it.
f23
Error f23. Exceeding the permissible level of the temperature difference between the supply and return lines.

f24
Error f24. Low liquid level in the heating circuit, the temperature rises very rapidly.
Perhaps this happened due to:
- Pump interlocks, or its insufficient performance.
- Happened system airing, and, as a result, the pressure has decreased, blow it out.
- Highway overlap. See if all taps in the system are open.
f25
Error f25. The protection system against the penetration of carbon monoxide into the room has been triggered. Why does the boiler turn off? When this malfunction occurs, the relay contacts open due to a violation of the air flow circulation.
The reason may be:

It will also be useful to clean the entire ignition group, including the burners.
f29
Error f29 (f29). Extinction of the flame during the operation of the boiler.
Consider the possible reasons:
- No gas supply to the boiler. Perhaps there is no gas in the line, you need to contact the gas service.
- Check grounding devices, phase, zero.
- The reason may also be burner clogging, to do this, remove the casing from the boiler by unscrewing the two bolts. Next, view the condition of the burner, if necessary, clean it.
f33
Error f33 (f33). The antifreeze protection system in the fan is activated. The contact in the relay does not close.

- Maybe, faulty control board and it needs to be replaced.
f62
Error f62. Gas valve defective.
What should be done.
Answers from specialists in the repair of the boiler Proterm Leopard
Question:
We have a leopard proterm boiler and this is the reason the sensor does not switch to hot water, when the temperature rises for heating, a knock appears in the boiler, if you open the hot water tap and drain the water, everything calms down. We don’t understand what the reason is, the master says it is necessary to clean the heat exchanger. I ask for advice.
If you have a heating filter, check it first, the three-way valve probably has nothing to do with it, because. as I understand you have hot water. Second - check if your circulation pump is working.
If the pump is running and the filter is clean (if it is in the system), then most likely the master made the right conclusion, but keep this in mind only if, when the heating temperature rises, there is a knock in the boiler and the temperature rises quickly. By the way, there may also be a problem in the three-way valve - sometimes the gaskets are erased, and it does not switch to the end.
Wall-mounted boiler Leopard 24 does not start. The piezo clicks but does not start. Writes an error F7. What does this mean?
The error is called "disconnection", that is, somewhere the signal from some sensor or the low voltage on the board does not pass. Try to pull the plug out of the socket yourself, and turn it over, because the phase-zero can be simply mixed up. The coolant pressure in the system may also decrease, and this must be checked.
The Protherm Leopard boiler broke down: there was a high temperature, and the emergency lamp lit up. No longer ignites. How to be?
It seems that due to overheating, the thermal fuse of the STB boiler has tripped and the boiler is blocked. If your boiler is equipped with an atmospheric burner, you can unblock and start it yourself. On the left side of the boiler, find the black cap and unscrew it, under it there will be a button that should be pressed. After that, the boiler should start.
Please tell me what is the maximum temperature in the pipes that can be set on the boiler Proterm Leopard 24 btv / bov house area 100 sq.m
The maximum temperature is 75 degrees C.
Proterm leopard 24 BOV up to 50 gr. heating, everything works fine, if you add it, it turns off after a minute and gives an F6 error, what is it?
Air monostat or fan failure.
Protherm Leopard 24 gives error F6 on first connection. Could you tell me what could be the problem, could it be a problem with the installation?
Error F6 - fan monostat malfunction.
Cauldron leopard 24 BOV 17 series. I have an F8 error on what does this malfunction mean, and how can I fix it?
The gas valve may be defective.
The Proterm Leopard unit stopped. Shows error F8. What can I do to make it work again?
Error F8 - gas valve malfunction. Perhaps it is out of order and needs to be replaced with a new one.
Hot water pressure drops. Those. wash and take a contrast shower - one and the same thing. We did not find specialists. How to deal with it?
Most likely you have a well. It was the same on this and another boiler. Everything was solved simply. First you need to check the pressure in the accumulator (blue or red tank), it should be about 1.5 bar, if less, then pump up. If water runs out when you press the valve, then you need to change the inner membrane. After all this has been checked, we check whether the pressure also drops. If yes, then the relay
pressure, you need to set the pump shutdown threshold to a higher pressure.
Tell me, at the proterm of the leopard, water flows from the air blower, which is behind the pump, what to do.
If the valve is leaking, then it is most likely stuck, look, there should be a cap on the air duct, screw it all the way.
Tell me, please, what could be: When the heating is on, after using hot water, the pump makes a lot of noise, the temperature rises to 80 degrees. then slowly decreases. By time minutes 5. Depends on the time of using the DHW. It used to be like that. I cleaned the filter screen in the heating system, and everything became normal. Now the network is clean.
Noise in the pump may be associated with such a phenomenon as cavitation, which can be caused by air dissolved in the coolant. When DHW is withdrawn, the pump stops and at the same time air begins to be released in it, therefore, the longer the withdrawal, the more air is released.
After the DHW withdrawal is stopped, the pump turns on, cavitation appears, which leads to a decrease in pump performance and, as a result, to an increase in temperature. When cavitation stops, the pump returns to normal operation.
Boiler Leopard 24kW. In work 4 years. There were no problems. In this heating season, more than 60 degrees for heating does not give, although judging by the height of the flame during ignition, there is a margin of 30-40 percent. Also there was a knock in the boiler. The pump switched in 3 modes. Nothing changes. What could be the reason? Insufficient flow? Temperature sensor malfunction? Gas pressure?
The HW heat exchanger is clogged, when one of the tubes in the bithermic heat exchangers is clogged, boiling occurs in the hot water circuit, so the hot water sensor modulates the flame, because it is a priority in relation to the heating water sensor. It is easy to check, you pull off the hot water sensor, if the boiler reaches full power, then the heating water circuit is clogged.
I have a Leopard boiler, the problem is that the boiler does not produce the set temperature of 70 degrees. Gives out only 50 degrees. Help solve the problem.
I had to tinker with the settings, the minimum heating power was previously set in numbers 9, we caught up to 20, everything heats up perfectly. It is necessary to switch to the heating figures on the display and then hold down and hold the MODE button for a long time until something is displayed, then press it again until the number appears, in our case, as I already wrote, it was 9, the smallest power, pressing on plus caught up to 20 and then again on FASHION and that's it.

Heating equipment of the Czech brand is famous for its reliability. Practitioners say: if the Proterm boiler of the Leopard series malfunctions and error f1 appears on the display, the problem that caused it can often be eliminated on your own without calling the service wizard. The article explains in detail what should be done.
Wall-mounted boiler Protherm Leopard
- When any error is displayed, and not just the f1 code, you should not immediately look for the cause of the malfunction. The first thing to do is to restart the boiler (REZET switch). In 85% of cases, its performance is restored.
- If the fault code reappears, check the set parameters. Incorrectly "clogged" power Proterm Leopard often causes an error f1.
- During the initial start-up of the boiler, its cause may be a rephasing. The wall-mounted Proterm is connected to the 220/1f network, and if “0” and “F” are mixed up, its automation will give an alarm. It is necessary to pull the plug out of the socket, turn it over 180 0, insert and repeat the start.
Possible causes of error f1 Proterm Leopard
In the manufacturer's instructions, it is interpreted as the disappearance of the flame. There are several reasons for its attenuation (disappearance).
Problems with gas supply
- Check the supply of "blue fuel". To make sure that it is not blocked, you can check the stove in the kitchen. If it doesn’t “start”, for a private building it means one thing - the shut-off valve installed on the pipe has worked. You need to move its lever to its original position and try to restart the Proterm Leopard.
- Check the pressure in the supply line. With its value below the critical value for the boiler, the Leopard automation gives a ban on starting, but this will not particularly affect the gas stove; only the length of the flames will decrease somewhat. At facilities where cylinders are used for Proterm, the pressure is controlled by a pressure gauge on the reducer. When the “blue fuel” is depleted to the minimum allowable level, the tank must be replaced, and the f1 error will disappear when the Proterm boiler is restarted. If it is connected to the main pipe, this code may appear on the display due to contamination of the gas filter mesh.
Fan failure
Before removing the boiler casing, you need to clarify the expiration date of the warranty from the passport. The instructions for Proterm Leopard (clause 14 of the "Introduction" section) say under what conditions the manufacturer's obligations are canceled. This means that any maintenance, repairs will have to be paid.
![](https://i0.wp.com/fixbroken.ru/wp-content/uploads/2018/11/Shema-nastennogo-kotla-Protherm-Jaguar.jpg)
With the power off, the fan blades should spin easily. Breakage (burning of the winding, shaft deformation, bearing problem) is a rare case. As a rule, error f1 of the Leopard boiler appears due to a break in the power line of the fan motor, poor contact, or a temperature sensor.
In the latter case, you need:
- check the position of the reset button: it is on the sensor body (located in the upper part of the boiler, under the casing). If, after pressing and restarting Proterm, error f1 reappears, then the problem is most likely in the chimney;
- evaluate traction. It is possible that the smoke exhaust channel is clogged with debris caused by a small bird: there are enough options for the Leopard boiler to give an error f1.
Ionization sensor not working
- Check the integrity of the signal line, the reliability of the wire connection.
- The cause of the error f1 Proterm Leopard may be a contaminated electrode. It's easy to clean.
- If there is excess humidity in the room, then the boiler cavity must be dried. It is impossible to use an open flame - only a hair dryer or something similar (fan heater, supercharged heater). The cause of the f1 error may be moisture on the electronic board or the sensitive element of the sensor.
Overheat
The operation of the thermostat of the heating circuit is explained by a sharp decrease in the circulation rate of the coolant. In this case, there are several reasons for the f1 error on the Proterm Leopard display:
- failure, incorrect operation of the pump - oxidation or deformation of the shaft, impeller;
- clogged filter or primary heat exchanger of the boiler;
- leakage in the system, heating radiators, expansion tank;
- problem with the signal line of the temperature sensor (short circuit) or its failure;
- lack of "visibility" between the thermostat and the control board (you need to check the reliability of connecting the connectors).
With the rest of the reasons - the failure of the ignition transformer, the breakdown of the gas fittings, the malfunction in the electronic module - you cannot cope on your own. If all of the above recommendations for fixing the error f1 Proterm Leopard did not give a positive result, you need to contact the service center.
The double-circuit gas boiler Leopard from Proterm is a device that can operate on both natural and liquefied gas, equipped with a bithermic heat exchanger. The capacity of the liquid from the tap is 8 liters per minute, heated to 35 degrees.
Power consumption 135 W. Equipped with a built-in processor, monitors the operation of the device by comparing sensor readings. If a malfunction is detected, the gas supply is stopped and a failure code is displayed on the display.
This device is easy to operate, the efficiency in the heating season is 90%. Depending on the modification, it can be with natural or forced removal of combustion products.

Check the following:
![](https://i1.wp.com/boilervdom.ru/wp-content/uploads/2017/05/00x375.jpg)
Other malfunctions
The boiler does not turn on due to:
- no power supply, check the serviceability of the connection to the network, the voltage in the network, if it is less than 220V, install a transformer;
- low pressure in the gas line, contact the gas industry;
- shut off gas supply, open the faucet;
- no draft, make sure that the chimney is not clogged, the fan is working properly;
- electrode incorrectly installed regarding the jets, adjust the value between the electrode and the jets;
- gas valve defective, change to a new one.
The boiler usually buzzes due to a large amount of plaque in the heat exchanger, flush the heat exchanger, air may enter the system, remove air, the fan or pump may be faulty, check their operation.
Scheme of the boiler Proterm
Insufficient water pressure in the hot tap, check and wash the filters, if they are deformed, torn, replace them.
The flame is orange, burns unevenly - this happens if the burner and jets are dirty, clean them of soot with a brush and rag, blow the jets with a hairdryer.
Of course, most readers are concerned about the issue of "technical treatment" of heating devices and how to fix the problem. Before covering this issue, you need to know the device, product characteristics and its capabilities.
The diagram shows the device of a gas boiler Proterm of a Czech manufacturer.
The main technical indicators include:
- Efficiency: 90-92%.
- Possibility of adjustment: "winter-summer".
- The function of heating water in boilers.
- Installed overheating protection.
- Ability to work in several directions: on main gas and liquefied coolant.
- The gas boiler is made on a cast-iron base.
This is the minimum set of technical characteristics for a simple layman that you need to know about. More detailed information is indicated in the technical data sheet attached to the purchase of the product.
Types of Czech gas-fired boilers
The manufacturer offers the domestic buyer to purchase equipment of its own production, which are divided into:
- by the number of circuits: a double-circuit version of the boiler or a single-circuit design;
- with installation orientation: wall or floor version.
On the domestic market, you can purchase various modifications of Proterm heating equipment.
Types of gas boilers Proterm are the most interesting for the domestic market
On sale there are many modifications. The most common are gas two-chamber boilers with biometric heat exchangers: Leopard and Lynx.
The equipment is made at a high technological level and complies with EU standards. However, no matter how good the technique is, it tends to fail at the most inopportune moment.
Read below about malfunctions of heating devices and troubleshooting methods.
Gas boiler Proterm Leopard equipment malfunction.
There are certain error codes, thanks to which you can understand what happened to the equipment. The most common malfunctions of the boiler leopard 24.
F0
Signals to us about a decrease in the pressure of incoming water with values below 0.6 bar. If the heating water pressure is low, the system switches off automatically. This is signaled by a built-in diode (see the "Pointer" symbol).
In this case, it is necessary to increase the value of the incoming liquid to the level of 1.2-2 barrels. After stabilization of the pressure, the boiler will automatically resume operation in the planned mode.
F1
The flame is gone. The gas supply was interrupted and the wick went out. You need to pay attention to the emergency thermostat. Try to restart it.
Another reason may be a turned off draft sensor (we are talking about boilers and chimneys).
Another problem that affects the disappearance of the flame is the wires are reversed: phase and zero.
Loss of flame can be caused by a problem with the automatic ignition, gas valve and malfunctions in the control system.
F2
The heating water sensor has failed. In this case, the malfunction is due to a break in the above element. It is possible that t0 of the cooling water has crossed the mark below 3 0 С. The system is disabled. The resistance of the sensor needs to be checked. Pay attention to the cables running from the sensor to the control panel. Find out, t 0 RH, inspect the system for freezing.
F3
Often malfunctions of the gas boiler Leopard 24 associated with overheating. Cooling down, the system resumes its work. It is necessary to check the heating pump: it may be clogged.
Photo: Heat exchanger of the Leopard 24 gas boiler.
Check the condition of the heating filter and check the heating water heat exchanger. The reason is the same: clogging of the working elements.
On a note. In work, use the non-freezing mixture recommended by the manufacturer: "AlycolTermo".
F4
The water sensor is out of order. There was a short circuit of the sensor responsible for the t 0 mode of the tank. In this case, the operation of the boiler will continue in the mode: “Heating water heating”.
Heating of incoming water is switched off. The reason may lie in the resistance of the sensor.
Please note that when the circuit is broken, the error code is not displayed! The control unit will show that the storage tank and or the sensor are not connected.F5
External sensor failed operating in equithermal regulation mode. Attention should be paid to correct connection of the sensor and the element itself.
It is clear that this is an incomplete list of possible technical failures in the operation of Proterm gas boilers.
More detailed instructions and errors are indicated in the technical documentation. In addition, you can get knowledge on the Internet.
There are plenty of videos on the net that talk about problems and how to fix them.
For example, learn how and with what, at home, to clean the heat exchanger.
Without a doubt, some of the problems can be fixed on your own. But most breakdowns require the intervention of specialists.
In matters of safety and quality elimination of technical failures in the operation of gas-fired boilers, it is necessary to seek the help of specialists at a service center.
Gas boiler Proterm Leopard malfunction shows 104.Do not take risks and self-medicate. This can lead to serious problems. Therefore, you will have to shell out money from your pocket for unplanned re-repairs.When choosing a technical assistance center, pay attention to the availability of certificates and the duration of the center: how long the company has been providing this kind of service.
Speaking of quality, it makes no sense to use the workshops located near your home. Moreover, the masters go to you at the specified address.
Carry out regular preventive maintenance of the equipment. This is the key to the stable operation of the gas boiler.
Finally
No matter how manufacturers praise their products, problems still arise. Separate elements and blocks fail. This cannot be avoided.
This means that it is necessary to approach the issues of technical problems calmly and carefully.
High-quality repairs with a guarantee for the work performed can only be given by specialists of the service center. They use original parts and accessories.
If you are confident in your abilities, you can take on some of the work to eliminate deficiencies. But this is a risk: keep that in mind. Good luck to you!
