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 Junkers ZWE 24-3 MFAD reconditioned. Circuit with two digit display, red light indicators and orange relay. Contrast 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.
