Honeywell PCB Saunier Duval Thema NOx F24 Ref. 0020076179
The Honeywell Saunier Duval Thema NOX F24 PCB (control board) Ref. 0020076179 is a component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, lock out, or behave erratically, displaying faults such as 13, which indicates a fault in the main printed circuit, or 11, which signals a lack of reception by the main board. This board is compatible with boilers from the Thema NOX range, such as the F 24 model, as well as with some models from the Supermaster and Supermicra ranges, among others. It is recommended to replace it upon detecting these symptoms or faults.

How to check if ref. 0020076179 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 0020076179. 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 0020076179 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 boiler does not turn on when the switch is pressed.
Cause: The PCB is unresponsive and does not allow the startup.
Check if there is power reaching the PCB before considering it faulty.
- 02
An intermittent fault code appears.
Cause: A fault in the PCB causes intermittent loss of communication with some component.
Check if the fault occurs with vibrations or knocks in the boiler, which could indicate a loose connector instead of a fault in the PCB.
- 03
The remote control or the panel do not respond, even though they are powered.
Cause: The PCB does not receive or process the signal from the remote control.
Check that the cable or bus between the panel and the PCB is properly connected.
- 04
The boiler turns off by itself during the cycle repeatedly.
Cause: The control electronics interrupt the supply due to erroneous readings from its circuits.
Note if the shutdown occurs at the same time; this helps to differentiate a PCB fault from a sensor fault.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 13 | Main PCB fault. | The main PCB is faulty or has defective internal/external connections; check the fuse and voltages of the PCB (230/5 V supplies) and connectors. If the issue persists with correct wiring and peripherals, replace the PCB. |
| 11 | No reception from the main PCB (MMI line). | Communication fault towards the PCB (receiver/MMI input of the PCB) or the cable between interface and PCB; check continuity of the MMI lead and 5 V on the interface. If the fault persists with a good cable/panel, the PCB is the cause. |
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.
