my boiler is firing up even when the water/heating are off on the programmer. It is not on the frost setting; is there any other reason that could be causing this? if not then I has a wireless thermostat fitted a few weeks ago that seems to be working fine but perhaps it could have been something to do with the way that was wired?
Ps it is a baxi solo boiler
Thanks
