Hi all
I have a Worcester Danesmooor 15/19 oil boiler and a Drayton LP522 programmer in the airing cupboard. This is all wired in to a junction box and works fine until the timer clicks off and the boiler stays on. The red light on the boiler will not go out and I have to cut the power at the junction box to stop the heating at night, otherwise the pump hums away merrily all night.
There are two mid position valves one of which appears to move OK when the heating is switched on to HW and CH.
I was considering changing the Drayton programmer but will take advice if anyone believes they can help in this issue.
