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.

Reconditioned electronic board Junkers ZWE 24-2ADE 23. Green main board with a display and red connectors. Visible marking on the module: 24V. Check the board code, revision and connectors; the same boiler model alone 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.
