Dear All,
I have a heating system that wont switch on. No power to boiler but programmer powered up and lit up fine . Boiler is an oil fired Wrocester 20/25 Danesmoor and the tank is a Megaflo 210. I have two Honeywell motorised valves one is a V4043H1056 and the other at the bottom of the tank is a Honeywell 272848. The boiler wont switch on and there's no power or reset light. When I manually opne EITHER of the motorised valves the boiler fires up for a second or two then swtiches off as the arm moves back slightly even when recessed in the manual detent.
Is it the motorised valves or something else?
Thanks for any pointers and best wishes for 2011
Jim
