Danfoss controller has blown, this was after a series of blown fuses [3 amp]in the supply to the controller, not sure if there is a problem with wiring or the contoller itself was faulty, have replaced with a spare unit but now when selecting heating or hot water the three port valve opens and the pump runs but the boiler does not fire up.[pilot light is lit]There is a live supply to the boiler [potterton kingfisher floor standing model] even when no hotwater/heating is selected.Is this correct?
