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 screen freezes, always displaying the same data without updating.
Cause: The display module does not update the information even though the boiler changes state.
Turn off and on the boiler from the main switch and wait a couple of minutes before ruling out the module.
- 02
When pressing the buttons, nothing happens, or it takes several presses for it to respond.
Cause: The module's keyboard loses sensitivity due to use or humidity.
Test each button separately and check if any of them fail more than the others before replacing it.
- 03
The screen backlight flickers or stays on without reason.
Cause: A fault in the electronics of the module affects the power supply to the display.
Check the connector that links the module to the boiler, ensuring that it is not loose or corroded, before replacing it.
- 04
The boiler is working, but there is no information displayed on the screen, as if it were disconnected.
Cause: The display and keyboard module has lost communication or power from the main PCB.
Check the wiring and the flat connector that links it to the boiler before declaring the module faulty.
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.
