hi guys
I have a very weird fault on a system at clients property. I have suggested that wiring more than likely needs looking at.
So standard open vent system with ideal classic heat only installed hot water seems to be working fine.
however when the central heating is turned on at the programmer and the room stat is set at 10 degrees(the house is definitely above 10 degrees) the boiler is still firing and what it seems to be doing is shutting off when the boiler stat is satisfied and firing up again moments later to maintain this.
I have had the room stat off the wall and we have on switch live to earth- 240v, live to earth 240v and neutral to earth- 0v. obviously when the switch is not in place we are not supposed to be getting 240v from the switch live.
so I guess my question is other than the wiring being defective is there any other reason why I would be getting 240v on the switch live from the stat?
any help you can give would be greatfully received guys
Cheers
Pooly
