Hi - I have a potterton EP which looks like the EP4002 but in brown. Last night (hottest of the year!) my central heating came on even though the slide was still switched to off. I fiddled with the switch and eventually resorted to pulling it out to check the contacts but the only way to get the heating off was at the boiler.
Before I go the expense of installing a new EP can anyone tell me if there is a way of diagnosing and fixing the problem? Could it be battery related?
My wife is going mental because I installed spotlights in the kitchen at the weekend and she is convinced the problem must be related so any help would be much appreciated!
