In the summer, as a preventative measure, I wanted to flush the heating system. I called a dozen companies and spent a week - either the price is high, or they don’t inspire confidence, or there are some other restrictions. Some said that they would wash it for 3 days, removing all the batteries in the house - they also announced 50 thousand.
. The next day they arrived and did everything in one day using some special compressor + chemicals. Fast,…

At the beginning of January 2017, it was very cold in the Moscow region and our gas boiler went out and we could not start it. Before this, he periodically “capped” and “clicked”, but we did not attach any importance to this. And then... New Year, the whole family is at the dacha, and the boiler is broken. It's good that the experts “Complex of Ideas” came and solved our problem. Almost froze :)

I recommend it to everyone! The masters' telephone number was written with a marker directly on the cauldron.

I would like to write a review about the work of an employee of the Complex of Ideas company. When the cold weather came, a problem arose with heating boiler in a country house - I wrote an error: I don’t remember what number. On the phone they found the first website on the Internet and called. They arrived, fixed it, and took very little money. Very prompt, polite and only stayed pleasant impressions. It seems the employee’s name was Vadim or Vlad - I don’t remember exactly =)

07.05.2016

I spent the whole weekend trying to connect the boiler at the dacha to heat water... I went to the market 3 times for additional parts, scoured the entire Internet - I just can’t seem to get it done. It doesn’t turn on, then it leaks, then something else. I found this site on the Internet, called - they came and did in 50 minutes what took me 2 days! I should have called right away. I would have rested better. Next time I'll do that!

16.03.2016

I express my gratitude to specialist Victor from "Complex of ideas"! He came, fixed our gas boiler, replaced something there - voila, everything worked. I couldn't have done it on my own.

Thermon boilers - Troubleshooting

I have a Thermona therm 14 TCL double-circuit boiler. Lately he has started supplying too cold water to the hot water supply (heating is not going well). Using the knob on the front panel, I regulate the water supply to the hot water supply to maximum, but one or two LEDs light up, very rarely three. I tried reducing the water pressure, but it didn't help. This problem happens periodically (not always). If you switch the hot water tap several times in the on/off positions, the device starts to work as expected. I would like to note right away that the degree of contamination of the heat exchanger is not high, since last summer I removed and checked it. It was perfectly clean, and this was after 7 years of work. What should you pay attention to first to solve this problem?

According to the passport data, this boiler is capable of heating water at 25C with a flow rate of 7-7.5 liters. If tap water, coming to you, is about 5-10 degrees, then the maximum possible heating will be no more than 30C (only one electrode will burn on the panel). By adjusting the flow rate, you can increase the temperature of the supplied water to 40C, and sometimes up to 50C. But it is important to consider that if you reduce the flow rate to 3 liters per minute or less, the flow sensor in the DHW circuit may not work and the burner will automatically turn off.

After installing the Thermon gas wall-mounted boiler, the hot water supply stopped working. We implement it quite simply: water is supplied to the tap through a single heat exchanger. Heating circuit works, turns on and heats up three times. If you open the DHW tap, error F1 appears on the display. That is, in his opinion, there is a flow, but there is no ignition. Despite the fact that with heating everything is fine. I will also note that if the tap is opened, then when it works for heating, it turns off. This means that there is still a flow, otherwise the unit would not react like that. For me, this situation is not clear: there is ignition, there is also flow, but the device does not work correctly. Tried unplugging
I did a reboot, even turned the plug over. Did not help. Although the device is supplied good food, since it is connected through a stabilizer.

In my opinion, this malfunction can occur in two cases: In the heat exchanger operating on the DHW circuit, some deposits have appeared that interfere with the normal flow in the system. The temperature sensor installed on the DHW circuit does not work correctly, namely, it greatly overestimates its value. Although, it is possible that there are two problems at the same time.

We installed and put into operation a therm duo 50 gas boiler. The following problem arose. When starting up, a spark appears during ignition, which is supplied to the burner and quickly goes out. The display shows error E01. What to do?

Error E01 most likely means the ignition electrode is dirty. You should clean it carefully with a cloth. The gas pressure may also be weak, and because of this the flame is very low (the device does not see that it is there). The flame sensor insulator may be broken or the control board may have failed. You also need to make sure that there is no leakage to ground anywhere.

We have a single-circuit gas boiler Thermon 14, operating in summer mode. To turn on the boiler, it repeatedly tries to start with high temperature in the boiler. How to deal with this?

The three-way valve may be stuck. To fix the problem, you need to force it to open and close several times. The boiler temperature sensor may be damaged. If it is operating correctly, the three-way valve will not open until the temperature in the device exceeds the temperature in the boiler. The control board may also malfunction, since all algorithms for the operation of the 3-way valve are written in it.

For some reason, the Thermona therm 35 gas boiler installed on the floor constantly goes out for no reason. The error can only be eliminated if a fan is directed at it. What is this connected with?

Most likely, in the room where it is installed there is not enough air for the flame to burn. Or the ionization sensor itself is clogged. I have listed the two most common reasons, but there may be something else at play here.

In operation Thermon 45. Yesterday the following problem occurred: the device stopped by mistake" sensor failure heating water"Do I now need to drain all the water from the system for repairs, and how can I repair the sensor itself?

Most likely, it got up due to error E04 (breakage temperature sensor heating). The presence of water in the heating system does not interfere with its replacement. You just need to block it shut-off valves. But the following malfunctions are also possible: short circuit in the circuit, dirty dirt filter, breakdown or incorrect operation of the pump. Because of this, the device overheated from the hot water circulating in the system.

In case of breakdown gas boiler Thermona 28 error E06 appears on the display. The instructions say that the problem is with the thermostat. Where is it located to replace the sensor?

Error E06 means that an emergency shutdown occurred due to overheating (emergency thermostat). Poor circulation in the heating system is also possible. If something happened to the hydraulics of the unit itself, it will also show this particular error. Check the filter, correct operation of the pump and sensor.

Thermona TCL-28, during operation, often began to show error E2. In addition, his pump burned out. Now it is necessary to flush the heating system, adjust and configure the entire device. Why did this happen, and what is the best way to perform the above procedures?

Error E2 is often indicated by low water pressure in the OS. There may be several reasons for this: a broken expansion tank or some kind of water leak in the system.

A 20 kW gas boiler is installed. When the hot water supply is turned on, it displays error E01. Then the scoreboard goes out and there are no signs of life. What could have broken?

It is possible that the ionization sensor touches the housing, thereby shorting the system. Another option: low current on the gas valve control coil. The tipping sensor may also be broken. And, as the most likely option, the control board of the device itself does not work.

We installed a Thermon gas wall-mounted boiler. When starting, it appears that work has begun, but the heating water supply pump does not start. After a while he stops. What could be wrong with him?

If we take the principle of operation of wall-mounted boilers, then they must be established that when not working circulation pump they don't even start. You need to somehow start the pump, then the unit will not stop in case of an emergency. On the back surface of the pump you need to open the plug with a screwdriver and slightly turn the armature. In this case, the device must be turned off. Perhaps the anchor is simply stuck to the surface and needs a little help.

We have a Thermon Duo 50 boiler installed. Error E01 occurs periodically, which entails turning off the device. You can only start it by force, or by turning on the restoration of the ignition system. After that, it works in standard mode (from 30 minutes a day, approximately). I checked the injectors and ignition electrodes. They are not contaminated. Called the masters from service department, and they expressed their version - the processor is faulty. Representatives of the gas service have their own version. They are sure that the reason lies in air lock(my site is located at the very end of the gas pipeline, then there is a dead end). My neighbors don't have these problems. Tell me, what's really going on with my device?

Your mistake is the most common with gas boilers. And there are a huge number of reasons for its appearance. These could be “dips” in the power supply voltage, problems with gas, breakdowns of the ignition and flame control electrodes, problems with the control board, oxidized contacts and much more.

I installed a Therm 50 boiler. Until recently, there were no complaints about its performance. However, recently it had to be turned off for 4 days. And now I can't get it to work. A spark fires for 20-30 seconds, and then the emergency light flashes and it never lights up. The error resets, but it doesn't go beyond a spark. The device is connected to the machine. Everything looks fine, there is gas. What could it be?

According to the PUE standards, a plug must be mounted so that visible disconnection of contacts can be made. You have installed a unit that depends on the phase. Try swapping phase and zero.

Already for a long time Three therm boilers are in operation and are successfully operating - two 28 TLX in cascade and one 32 TCLN. Their first pair in 5 years of work did not create a single problem. Maintenance (disassembly and cleaning, as well as adjustment) is carried out by me approximately once a year. More often there is no need. But I can’t cope with 32 TCLN. I can't even turn off the equithermal mode. It was possible to put it back into operation after disconnecting the sensor. I simply don’t pay attention to the error that occurs. How can I log in service menu this device?

To enter the service menu, you need to set all knobs to 7 o’clock, and then turn off the power to the unit itself. When turned on again, it will automatically start the self-diagnosis mode, and then display “CC” on the display for a couple of seconds. If this happens, then everything worked out and the weather-compensated mode is disabled. After this, by turning the knobs you can adjust it as required. Next, unplug it from the outlet.
Disconnect the sensor from the automation board by disconnecting the valve. You set the knobs on the control panel and return the power supply. Within 30 seconds the automation will perform a self-diagnosis.

The pressure gauge on the front panel of Thermon 14 began to show very large numbers. However, his work has not changed - everything is as usual. What could be causing this and is it necessary to make repairs?

This pressure gauge has nothing to do with the operation of the device. It only records the water pressure in it. The readings from this thermometer can be compared with any other pressure gauge in the system (if available).

When I start the Thermona 45 gas boiler, the following happens: the piez starts to work, but when I switch to the start mode, it goes out. What could it be?

Most likely, the flame generator has failed. This is the most common reason. But it is also worth checking the draft in the chimney, as well as the ignition nozzles for cleanliness.

I want to install Therm 28 LX control on the boiler three way valve to DHW using its board. Tell me if this connection and operation will be the same as in the description for LXZ. Or will the coolant stop when switching?

The algorithm is the same.

I use a 28 LXZ turbocharged gas boiler. Lately, two errors have been appearing: E01 - constantly, E08 - much less often. When I reset the errors, its operation is restored for a while. The device itself has been serviced quite often. Can I eliminate this problem yourself, or will you need specialists?

The fan and chimney need to be cleaned. If this does not help, you will need to replace the monostat.

My device worked perfectly, the service was always carried out on time. And recently, error E01 began to appear. And yesterday E07 was added to it. What happened to him?

Judging by the errors, there are problems with its ignition, with the chimney, or a breakdown of the monostat. Perhaps your supply ventilation is installed incorrectly or your chimney is frozen.

For some reason my boiler suddenly stopped due to error E06. How to fix it?

Error E06 corresponds to emergency overheating of the coolant. You need to check the dirt filter first, because if it is heavily clogged with dirt, the circulation of water in the system is disrupted. Look for the filter on the return pipe between the two valves. Take it apart and clean it.

This error indicates that when water is heated, it overheats. One of possible reasons There may be a breakdown of the temperature sensor responsible for heating the water. The heat exchanger may also be “clogged” with scale.

Please tell me how you can regulate the temperature of hot water in model 28 LXZ 10. The knob located on the control panel does not work, and when the master made the settings, he did something inside under the lid. I needed to change the settings, but I don't remember how to do it.

Remove the front cover of the device. On the bar below it you need to find a hole in which the slot of the DHW thermostat is visible.

The Thermona 23 tcl worked for five days without any breakdowns or any comments. A couple of weeks ago the pressure on the pressure gauge rose to 2.5, and the explosion valve began to leak. How can I find out: I have a problem with the heat exchanger or with the make-up tap. Finding out the causes of the problem, I learned that my unit was equipped with a heat exchanger made by the Italian company MUT. And as I read, there are very bad reviews about it. Heat exchanger, what good and trusted company can I replace it with?

It is necessary to set the air pressure specified by the manufacturer to expansion tank. About 80-90% of boilers are manufactured without an integrated make-up line.

I have a 14 TCL boiler installed. When you turn it on, for some reason the fan does not start, but the fan itself stops due to an accident. An inspection of the device did not reveal any visible wire breaks. The vacuum relay was recently replaced. What else could be the cause of this problem?

Your model has a two-position vacuum relay. And it is this that commands the closing and opening of contacts (features of operation depend on the model itself). Since you have ruled out a problem with the relay, the breakdown is most likely in the control board.

Thermon boiler 28 is connected. Lately there has been a problem during startup. If it has been turned off for a long time, then upon startup it works for exactly 10 seconds and then turns off.

You have a device with natural draft installed. For their correct operation, it is very important that the chimney is in good condition. It's possible your traction rollover sensor is tripping and that's why it stops when it crashes. Then, after it cools down, it becomes possible to start again. Check the chimney for permeability and ensure better air supply to the boiler room.

Thermon boiler 14 is faulty. When looking for a possible breakdown, I checked everything I could, but did not find the cause of the damage. The only thing I noticed was that the burner flame was yellow for some reason. Could it be a gas quality problem?

Check the inlet gas supply pressure (it is probably insufficient), or you have problems with the air supply. Once again you need to check the device for damage.

The Thermon double-circuit boiler (28 kW) broke down. Doesn't heat water. What could be broken in it? And how much can repairs cost?

An unexpected stoppage of DHW operation indicates that the flow meter is broken or the heat exchanger is heavily contaminated. Check the operation of the flow sensor and, if necessary, install a new sensor.

The boiler pressure gauge shows that the pressure in the tank is too high. But everything is normal on the batteries, in the heating system, and the pressure. Is it possible that the pressure gauge itself is dirty? Can it be replaced if it breaks?

If the pressure in the apparatus really exceeded acceptable standards, would have worked emergency stop. The pressure gauge can be checked as follows: release all pressure from the device and look at the readings. Its arrow should show 0. We also advise you to check the dirt filter, since it is its cleanliness that directly affects the readings of the pressure gauge on the unit. If you need to change the pressure gauge itself, be prepared for the fact that you will have to drain the water from it.

Thermon boiler 50, stopped feeding hot water. Moreover cold water comes in, but nothing comes out at all. What to do?

If water enters the hot water supply but does not come out, you definitely need to check the heat exchanger. It is also possible that the water supply is mechanically cut off somewhere. Perhaps the gasket was squeezed out and clogged the passages in the heat exchanger. Try applying water in the opposite direction.

We installed a wall-mounted Thermon 14 boiler. When we try to start it, it stops after three seconds. Previously, a mechanical blow to the device helped. Now this doesn't work either. What is the reason for the breakdown?

If you believe your description, then there is a loose contact on the board or some other place. Check the electrical system, clean and correct all contacts on the board.

Model 28 tlxz, constantly keeps the burner on maximum power, and does not try to control it. Maybe it's worth checking the gas valve modulation coil? How to do it? How should the circuit be closed: maximum or minimum?

The coil cannot change its state; it is not a relay. Its main property is the presence of resistance. If the valve operates at maximum, then everything is fine. There is a possibility of the valve sticking open, but it is very small. Check the board.

The device constantly stops due to an emergency when the DHW circuit is running. What could be the problem?

Check the flow sensor or secondary heat exchanger for proper flow.
