boiler fires up when the programmer is off
when the boiler was running i checked the 2 2 ports and both are shut down,these are drayton valves, are these know for the micro switch to stick?
both room and cylinder stats are working,i tested these when i turned the programmer on
only thing i can think of now is pcb
anyone confirm this?
basically when powered on at fused spur with programmer off the boiler fires up and overheats as the zone valves are not open and the pump runs
