Thermona Boilers - Troubleshooting

I have a Thermona therm 14 TCL double-circuit boiler. Recent times he began to supply too cold water to the hot water supply (heating is bad). Using the knob on the front panel, I regulate the water supply to the hot water supply to the maximum, but one or two LEDs light up, very rarely three. I tried to reduce the water pressure, but it did not help. This problem happens periodically (not always). If you switch the hot water tap several times to the on / off positions, the appliance starts to work as expected. I want to note right away that the degree of contamination of the heat exchanger is not high, since last summer I took it off and checked it. It was perfectly clean, and that's in 7 years of work. What to look for in the first place to solve this problem?

According to the passport data, this boiler is capable of heating water by 25C at a flow rate of 7-7.5 liters. If tap water coming to you, 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 up to 40C, and sometimes up to 50C. But it is important to take into account that if the flow rate is reduced to 3 liters per minute or less, the flow sensor in the DHW circuit may not work and the burner will be automatically turned off.

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

In my opinion, this malfunction can be 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.

A therm duo 50 gas boiler was installed and put into operation. The following problem has arisen. When starting up, a spark arises during ignition, which is fed to the burner and quickly extinguishes. The display shows an error E01. What to do?

Error E01 most likely means that the ignition electrode is dirty. You should carefully clean it 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). The flame sensor insulator may be broken or the control board has failed. You also need to make sure that it does not break through anywhere.

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

The three-way valve may have turned sour. To fix the problem, you must force it to open and close it several times. Possible breakdown of the boiler temperature sensor. If it works correctly, the three-way valve will not open until the temperature in the appliance exceeds the temperature in the boiler. The control board may also fail, since all the algorithms for the operation of the 3-way valve are written in it.

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

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

In operation Thermon 45. Yesterday there was such a problem: the device got up by mistake "heating water sensor failure". Do I now need to drain all the water from the system for repairs, and how can I fix the sensor itself?

Most likely, he got up by mistake E04 (breakdown of the heating temperature sensor). To replace it, the presence of water in heating system does not interfere. You just need to close the shut-off valves. But such 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 in the thermostat. Where is it located to replace the sensor?

Error E06, means that an emergency shutdown has 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 exactly this error. Check the filter, the correct operation of the pump and sensor.

Thermona TCL-28, when working, it often began to show an E2 error. In addition, his pump burned out. Now you need to flush the heating system, adjust and adjust the entire device. Why did this happen, and what is the best way to follow the above procedures?

E2 error indication is more often given by low water pressure in the OS. There may be several reasons for this: a broken expansion tank or some kind of water leaks in the system.

A 20 kW gas boiler was installed. When the hot water supply is turned on, it displays the 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, and thereby closes the system. As an option also: a weak current on the gas valve control coil. The thrust rollover sensor may also be broken. And, as the most likely option, the control board of the device itself does not work.

Installed a Thermon gas wall boiler. At start-up, the appearance of the start of work is created, but the water supply pump for heating does not start. After a while, he stops. What could happen to him?

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

We have a Termona Duo 50 boiler installed. Periodically, an E01 error occurs, which entails the shutdown of the device. You can start it only forcibly, or by enabling the restoration of the ignition system. After that, he works in standard mode (from 30 minutes a day, approximately). I checked the nozzles and ignition electrodes. They are not contaminated. I called the technicians from the service department, and they expressed their version - the processor is faulty. The representatives of the gas service have their own version. They are sure that the reason lies in airlock(my site is located at the very end of the gas pipeline, then there is a dead end). My neighbors do not have such problems. Tell me what is really going on with my device?

Your mistake is the most common with gas boilers. And there are a lot of reasons for its appearance. These can be "dips" in the mains voltage, problems with gas, breakdowns of the ignition and flame control electrodes, problems with the control board, oxidized contacts and much more.

Installed a Therm 50 boiler. Until recently, there were no complaints about its operation. However, recently it had to be turned off for 4 days. And now I cannot start it up. For 20-30 seconds, a spark is triggered, and then the emergency light flashes and it does not light up. The error is cleared, but the matter does not go beyond the spark. The machine is connected to the machine. Everything is outwardly in order, there is gas. What could it be?

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

Already long time There are three therm boilers in operation and successfully operating - two 28 TLX in a cascade and one 32 TCLN. The first pair of them 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 not necessary. But I can't handle 32 TCLNs. I can't even turn off the equithermal mode. It turned out to be turned on after disconnecting the sensor. I just don't pay attention to the error that occurs. How can I enter service menu this device?

To enter the service menu, you must set all the 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-test mode, and then will display "CC" for a couple of seconds. If this happened, then everything worked out and the weather-dependent mode is disabled. After that, 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. Extend the knobs on the control panel and turn on the power supply. Within 30 seconds, the automatics will make a self-test.

The pressure gauge on the front of Thermon 14 began to show very large numbers. However, his work has not changed - everything is as usual. What can this be connected with 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 reading of this thermometer can be compared to any other pressure gauge in the system (if any).

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

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

I would like to install on the Therm 28 LX boiler the control of a three-way valve for 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. Recently, two errors have appeared: E01 - constantly, E08 - much less often. When I reset the errors, its work is restored for a while. The device itself was serviced quite often. Can I fix this problem myself, or will I need specialists?

It is required to clean the fan and chimney. If this does not help, then you will need to replace the monostat.

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

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

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

Error E06 corresponds to emergency overheating of the coolant. First of all, you need to check the mud filter, since if it is heavily clogged with dirt, the circulation of water in the system is disturbed. Look for the filter on the return pipe between the two valves. Disassemble and clean.

This error indicates that when the water is heated, it overheats. One of possible reasons there may be a breakdown of the temperature sensor responsible for heating the water. And also the heat exchanger can 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 the wizard, when making the settings, did something inside under the lid. I needed to change the settings, and I do not remember how to do it.

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

Thermona 23 tcl worked for five bodies without breakdowns and any comments. A couple of weeks ago, the pressure on the gauge rose to 2.5, and the explosive 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 found out that a heat exchanger made by the Italian company MUT is installed in my unit. And as I read, there are very bad reviews about her. With a heat exchanger, what good and proven company can I replace?

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

I have a 14 TCL boiler installed. When it is turned on, for some reason the fan does not start up, but it stops itself due to an accident. Inspection of the device did not reveal any visible wire breaks. The vacuum relay has recently been changed. What else could be the cause of this problem?

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

Thermon 28 boiler is connected. Recently, a problem has arisen at startup. If it was turned off for a long time, then at startup it works for exactly 10 seconds and then turns off.

You have a natural draft machine installed. It is very important for their correct operation that the chimney is in good condition. Perhaps your thrust rollover sensor is triggered, and that is why it stops in an accident. Further, after it cools down, it becomes possible to start again. Check the chimney for leakage and provide a better air supply to the boiler room.

Thermon 14 boiler is faulty. When looking for a possible breakdown, I checked everything I could, but did not find the cause of the damage. He was the only one who noted that the flame of the burner was somehow yellow. Maybe the problem is the quality of the gas?

Check the inlet gas supply pressure (probably insufficient) or you have a problem with the air supply. Once again, you need to check the device for breakdowns.

The thermon double-circuit boiler (28 kW) has broken down. Does not heat water. What could have broken in him? And how much might the repair cost?

Unexpected interruption 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 indicates that the pressure in the tank is too high. But on batteries, in the heating system, with pressure, everything is normal. Is it possible that the pressure gauge itself is dirty? Can it be changed in the event of a breakdown?

If the pressure in the apparatus really exceeded allowable norms, its emergency stop would work. The pressure gauge can be checked as follows: release all pressure from the device and look at the readings. Its arrow should point to 0. We also advise you to check the mud filter, since it is its purity 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 the water will have to be drained from it.

Thermon cauldron 50, has stopped dispensing hot water... And cold water comes in, but there is nothing at all at the exit. What to do?

If water enters the hot water supply, but does not come out, the heat exchanger should definitely be checked. It is also possible that the water supply is mechanically shut off somewhere. Perhaps the gasket has squeezed out, and it clogged the passages in the heat exchanger. Try to feed the water in the opposite direction.

The wall mounted Thermon 14 boiler was installed in operation. When you try to start it, it stops after three seconds. Previously, mechanical shock to the device helped. Now that 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 in some other place. Check the electrical, clean and fix all the contacts on the board.

Model 28 tlxz keeps the burner at maximum power at all times and does not try to operate it. Maybe you should check 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 is operating at maximum, then everything is normal with it. There is a possibility of the valve sticking open, but it is very small. Check the fee.

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

Check flow sensor or secondary heat exchanger for flow.
