5% of the time my Suprima boiler won't fire up when the programmer enters the timed start.
I have an open vented system in a 3 bed terrace, the programmer and roomstat are both Salus (new), I replaced the honeywell 2 port valve on the CH circuit and put a new PCB in the boiler. The programmer is calling, the roomstat is calling and the boiler just hangs there fast asleep!
To get it to work, I switch off the supply to the wiring centre (I then hear the valve being wound back to it's rest position). When I switch back on and wait a few seconds the boiler does exactly what it's supposed to do n fires up.............what d'ya think experts?
