Frequent failures in the operation of heating equipment? Heating is blocked, and the Termet boiler displays an error on the display? Do not rush to call the master, we will tell you how to independently determine the cause of the breakdown. The table below shows all the decoding of symbols, as well as troubleshooting solutions.
Features of operation of gas boilers Termet
The traditional series is represented by the following models:
- Single-circuit. Are calculated on service of a heating contour. If a boiler is included in the piping, then heating will also be performed on the hot water supply circuit (DHW).
- Double-circuit. They heat the coolant for heating batteries and hot water. Heating is a priority, so hot water enters the system only when the faucet is opened. The rest of the time the room is heated.
- With open combustion chamber (ECO DP MINITERM ELEGANCE and ECO DP MAXITERM ELEGANCE). Support combustion due to the air from the room. To remove the smoke, a connection to the chimney shaft is required. Equipped with electronic control and a closed combustion chamber.
- With closed chamber (MINIMAX turbo, MINITERM turbo, uniCO turbo ELEGANCE). A coaxial chimney is connected to the sealed housing. Pipe-in-pipe design. Clean air enters through one tube to maintain the flame, and through the other, combustion products are removed. Modulating burner allows you to adjust the strength of the flame.
Condensing boilers should be singled out as a separate group: CRYSTAL and GOLD. The units have an additional heat exchanger that converts the energy of the waste products. Therefore, their efficiency reaches 100-110%.
Errors and malfunctions
Some codes block the operation of the boiler, others warn about the operation of one of the modes. There are cases when you can not do without the help of a master. But if you have repair skills, then you can fix the problem yourself. Check the instructions first to understand the location of the nodes.
Error Codes | What does | How to fix the problem yourself |
Error 01 (LED D4 flashes) | After three ignition attempts, there is no flame in the burner. | Turn off the gas supply valves to the end. Press the RESET key to restart the system. |
02 (diode D4 triggered) | Boiler overheating. The water temperature has reached a critical point of 95 degrees. |
|
Error 03 (D4) | The draft in the chimney is broken. |
|
04 (D4) | Heating NTC temperature sensor wiring is damaged. | Check the sensor, its wiring, contact tightness. |
06 (D4) | Malfunctions of the electrical part of the unit. | Contact the service center. |
07 (D4) | The gas unit modulator is out of order. | Repair the assembly, replace defective parts. |
08 (blinking red light) | The pressure converter in the heating system does not function. | Burner operation is automatically blocked, the pump continues to work for a while. Run transmitter diagnostics. It is recommended to contact the service center. |
09 | Incorrect pressure signal. | High pressure:
Low pressure:
|
10 | Hot water NTC temperature sensor connections damaged. | Check connections. Replace broken sensor. |
11 | Incorrect connection of power wires. | Reboot. Replace wires. |
l3 | Means reaching the heating temperature specified by the user. | |
E6 | Malfunction in the electronic unit. | Call the wizard for diagnostics. |
We have listed all the error codes of the Termet boilers. If you smell gas in the room, do not look for the cause of the leak yourself. Close the valves, open the window and call the gas service.
