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 Ferroli Bluehelix S 27C reconditioned. Contrast PCB code, its revision and connectors; sharing Boiler model is not enough to confirm equivalence. PCB square green with black Transformer, relays and connectors grouped at the edges.
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.

Application listed in the catalogue: Ferroli Bluehelix S 27C. The variant and configuration must match the installed equipment; this does not establish compatibility with other models.
No models are documented for that search.
Application taken from the catalogue, pending comparison with the installed variant. This does not constitute compatibility certified against an exploded diagram.
