    Hey, I’ve a 3 zone Programmer except when I turn on zone 3 the boiler doesn’t fire. Works fine for zone 1 and 2. Button lites up, light on motorised valves lights up but boiler does nothing? Anyone experience this?

    Sounds like a faulty zone valve.

    If the valves are EPH then there is a manual opening lever that you can switch to test.

    Yeah valve is opening fine but nothing going to the boiler to make it fire up.

    If it the newer EPH detachable actuator with the plug-in cable, swap two of them around to see if the problem moves to the different zone.
    Auxiliary switching may not be working.
