Saunier Duval Themafast C 30 E Display Control Module Ref. S1062200
When you turn on the hot water tap or start the heating, the Saunier Duval Themafast C 30 E Control Display Module Ref. S1062200 is responsible for controlling the operation of the boiler. This control PCB regulates the ignition, burner modulation, pump, and system safety features. If it fails, the boiler may not start, become locked, or operate erratically, displaying fault codes such as F11, F17, or F19. It is compatible with models such as the C 23 E ALV, C 25 E, C 30 E, among others from the Themafast and Isotwin Condens ranges. It should be replaced when these operational issues occur.

How to check if the part number S1062200 is the piece 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 S1062200. 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 S1062200 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 front panel is off, with no indicators, but the boiler is still operating.
Cause: The module only controls the display and the controls; if it fails, the boiler can continue operating with the last command, but nothing can be seen or interacted with.
Check the connector and the cable that connects this module to the main PCB; a poor connection can cause the same issue.
- 02
The boiler is working, but the temperature and mode cannot be adjusted from the panel, although the buttons seem to be functioning.
Cause: The control module is not sending commands to the main PCB due to a fault in its electronics.
Disconnect and reconnect the flat communication cable to the PCB before replacing the module.
- 03
Letters or numbers appear on the display, either isolated, cut off, or continuously flashing.
Cause: A fault in the display module affects what is shown, even though the boiler operates correctly.
Perform a general reset and check if the fault reoccurs in the same location on the screen; if so, the problem is with the module.
- 04
The panel does not respond to any button presses, not even the power on/off button.
Cause: The membrane or the button circuit has lost continuity and does not send the command to the main PCB.
Make sure there is no moisture or dirt on the buttons before considering that the module is damaged.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F11 | No signal user interface | The interface/display PCB is not sending data to the main PCB (loss of communication). Check 5 V/power supply to the interface, eBUS harness/connectors between the interface and PCB; if the issue persists, replace the interface. |
| F17 | User interface fault | Fault in the interface/display board itself (microcontroller or circuitry), preventing its correct operation. Check power supply and communication; if replacing the interface resolves the issue, confirm the defect of the part. |
| F19 | Software interface incompatible with IRIS software | The version/firmware of the interface/display board is not compatible with the IRIS electronics of the boiler. Verify product/version code and install the correct interface or reprogram according to specification. |
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.
