Hi there,
I have a Potterton Flamingo 40 boiler in an open CH system (Honeywell programmer, Grundfos Selectric pump, ACL 3 port valve, Drayton mechanical room stat).
Whenever I turn on the hot water it works fine, and the same goes for the CH if the water is on. But the CH will not fire up in the boiler if I just turn on the CH - although the light on the controller does come on. The switch in the valve does not move when the CH is turned on.
Could it be the valve motor is kaput - or more likely that the room stat is not working (temp is turned right the way up to try & make it fire)?
Help v.much appreciated!
