That would be OK, I'd probably throw it in there anyway. Please have a play though, would be good forum knowledge.
Good point, I’ll maybe do a separate thread which might be risky as I’ll just fiddle with things and see what happens only to be shot down shortly afterwards by someone with a working brain that’s capable of reading a manual and following actual instructions.
“Just” setting my central heating timer nearly ended up with it being detached from the wall with the biggest hammer I could find.
My father in law is one of those strange people that can do DIY successfully without major cardiac arrest. He always says “when you run into a problem just walk away and come back later with a clear mind”
Now to me that walking away would probably involve running out into the road shouting, screaming and tearing clumps of hair out.
Come to think of it my FIL has no hair...
