The thermostat in the hall is set at 10° but the radiators are on. The radiators can be on whether the boiler is on or not. There doesn't seem to be any errors on the board so I'm unsure as to what's happening. I looked at the bm2000 the other day and the time clock was all noughts so I have reprogrammed. But the radiators seem to come on of their own accord. Any idea's? ?

BM 2000.
Tried checking the fault codes on the ACB ?
If you can't or the display does not move.
Then ACB has failed / crashed.
If fitting a new one.
Would suggest fitting surge protection & lightening protection to the house electric supply.
