Anstoss Electronic control board FBW01-80 07050462

The Anstoss FBW01-80 07050462 PCB is an electronic control board for wall-hung boilers. It manages the ignition and safety sequence, receiving heat demand signals from the thermostat, starting the fan, reading the air pressure switch, energising the ignition transformer, opening the gas valve, and monitoring the flame via an ionisation electrode. It enforces pre-purge, safety time, and lockout if flame is not proven. This board is designed for the Anstoss FBW01-80 model.

Parts of this type are selected by matching the exact boiler model and original control series. The board's supply voltage, safety times, and connector pattern are set by the manufacturer, so swapping across models or series is not recommended. Before ordering, verify the original part number and boiler model to ensure compatibility.

When control boards of this kind fail, the boiler may not start, lockout after safety time, or fail to prove flame. Symptoms include fan not running, gas valve not opening, or no ignition spark. Check for correct power supply, wiring connections, and flame signal.
