Hmm I'm just a lowly electrician but I find programmers that go faulty regularly, switching on when they're not set. I changed one on Saturday, that was Danfos. And I witnessed the fault when I went to look initially, the heating and hot water where both on, the hot water is always set to off, and the heating wasn't within its set demand time. The Y plan valve was operating correctly, I checked that, after switching the FCU on and off it sorted itself out. So I fitted a new programmer, sorted.
And there was another just a few weeks ago where the heating would come on outside its set time and not during the demand time. I didn't change that one I left it to someone who knows more as it was a complicated system at a village hall, but the guy who deals with the heating only changed the programmer. I thought this was common?
