Version and connections
The PCB's shape alone is not enough to confirm that it is a suitable replacement. The service part number and installed variant complete the identification; programming or pinout cannot be inferred from a photo.

PCB Saunier Duval 8/411026 · Alimentación reconditioned. PCB power supply with mounted grey Transformer, blue Capacitor and Fuse. The label values correspond to the Transformer of the Circuit. Primary Transformer (label): 220 V · 50 Hz. Transformer (label): 24 V · 13 VA. Contrasts the PCB code, its revision and connectors; sharing Boiler model is not enough to confirm equivalence.
To identify the PCB, compare its labels and the layout of the connectors, relays and mounting points. A boiler family may include variants that need to be checked.
Compare the views from the same angle and check the complete identification of the removed part.
Choose a photo of your part to view it beside this unit. Compare the labels, connectors and mounting points from the same angle.

We repair boilers in Madrid and the surrounding areas. Installation is arranged separately from the purchase of the part.
PCB power supply with Transformer grey mounted, Capacitor blue and Fuse. The label values correspond to the Transformer of the Circuit. Compare these details with the withdrawn Part and their complete identification.
Transformer Marking Mounted: Saunier Duval 8/411026; Transformer Primary (label): 220 V · 50 Hz; Transformer Secondary (label): 24 V · 13 VA. They are readings of the unit photographed and not an equivalent list of references.
This tab identifies the Saunier Duval 8/411026 cataloged application. It does not credit equivalences with other versions; to expand them, it requires service documentation that relates the Part to the specific model.
