its also been a hash how it was wired up,the boiler only gets a live feed one the port valve actuator has moved over so the pump is not fed from the boiler either.As no bypass was fitted it has to stay like that.
i have a suprima 50 that tries to start up then shows a constant red light when it first starts up when the programme calls for heat/hot water.
when i press the reset the boiler starts up and continues working for the rest of the programme duration.
i am a qualified sparks so looking for any...
