Hi Piglet, I crumbled tonight and put heating on, however the clock is two hours slow. I don't know how to reset it. I've scoured on line for a manual (the one I have is rubbish) without success, well there's manuals but I can't find one that gives simple instructions to reset the clock.
I've always managed to get someone else to do it for me but I'm home alone right now. It's a Suprima HE boiler. :(
I have to nip out, will be back soon.
