[QUOTE="Lurch, post: 431402, member: 6967"] I think a drawing would be clearer as I am not convinced your description is totally correct (probably because mobile phones are a stupid idea for internetting IMO). You mention S plan but there is only 1 valve? Do you have a multimeter? Surely the first port of call should be the boiler control panel? Check for the correct voltages there and then if anything is on when it should be off or vice-versa then work out from there. [/QUOTE]
