PCB With LCD Screen Saunier Duval/Hermann Thema Condens F25, Ref. 0010028087
The control PCB governs the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, lock out, or behave erratically, which can lead to faults such as F.63, F.64, or F.70. This PCB with an LCD screen is compatible with models from Saunier Duval and Hermann, including the Thema Condens F25, F25 A1, and AS 25 A, among others. The confirmed manufacturer reference is 0010028087. It is advisable to replace it when the mentioned symptoms occur.

How to check if ref. 0010028087 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 0010028087. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the PCB 0010028087 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The screen does not turn on and the boiler shows no signs of operation.
Cause: The display and the control electronics are integrated, so a fault can affect both.
Check if the boiler ignites the burner or operates the pump; if there are no signs, the fault is likely in the entire PCB.
- 02
The buttons or the remote control do not respond, even though the screen is on.
Cause: The circuit that processes the pulses has stopped working.
Reset the boiler by cutting the power for 30 seconds; if the buttons still do not respond when turning it back on, there is a fault in the PCB.
- 03
The fault codes do not appear on the screen when the boiler is locked.
Cause: The display is not receiving or processing the information from the control board correctly.
Note when the boiler locks, whether it is when turning on or when requesting hot water; this information helps to confirm if the fault is with the display or another part.
- 04
The temperature cannot be adjusted from the display, the changes are not saved.
Cause: The control circuit for the setpoint does not respond to the commands from the display.
Check if the temperature returns to the same default value after each change attempt; that indicates a fault in the PCB.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.63 | EEPROM fault. | The EEPROM memory of the main PCB is damaged/corrupted; if NTCs and wiring are correct, the cause is the PCB. Check voltages and, if it persists, reprogram/replace the PCB. |
| F.64 | Fault in the electronics / NTC. | If the NTC sensors and their wiring do not present shorts or inversion, the fault is in the PCB electronics (measurement/processing stage). Check NTCs and continuity; if okay, replace the PCB. |
| F.65 | Fault: electronics temperature. | The PCB detects overheating or its internal sensor/power stage is faulty. Check ventilation/temperature and dissipation; if everything is correct, the cause is the PCB. |
| F.67 | Fault: electronics/flame. | The flame detection/control circuit on the PCB is not plausible or defective. Check the ionisation signal and grounding; if they are correct, replace the PCB. |
| F.70 | Invalid product code (DSN). | After replacing the display and PCB without readjusting the DSN or with incorrect coding resistance, the PCB locks the equipment. Verify/adjust DSN and resistance; if not accepted, incorrect/defective PCB. |
| F.32 | Fault: fan. | When the motor and wiring are fine, the fault may be with the PCB (multiple connector on PCB, output/driver, or PWM control). Check the power/signal from the PCB to the fan; if there is no correct output, replace the PCB. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
