[QUOTE="Jimboc, post: 394949, member: 26407"] Thanks for your help, I think I have sussed it. What I did originally was wire the live to the programmer and thermostat direct from the mains. The "switch" from the valves to activate the boiler, ie when they are calling for heat, was then working from that direct mains feed too. What the instructions say, and what I had ignored, was that any external controls must be wired from terminal three in the boiler and then switched back to terminal four in the boiler, this then turns it on when heat is called for. Obviously the boiler has permanent electrical feed from elsewhere to cater for the overrun. Quite why I was getting a live feed from terminal four without terminal three being connected I don't know, I suspect my previous mess up had made it throw a wobbly. Thanks again for your help, maybe this saga will help someone else. [/QUOTE]
