Hello All,
After trying WB website and two local heating engineers (both failed) i'm hoping someone here has heard of this before?
Problem... Boiler seems to work fine on/off etc but.... If my CH and HW are on, the CH will only fire if I switch the HW off, now just to explain further…. if they are both off and I turn the CH on, it wont work until I turn the HW on then off again, it's as though the switching off of the HW triggers the pump for the CH. I've been told the programmer ( WB twin channel) is fitted and wired properly.
I hope I've been clear enough, like I said, seems to be an unusual problem?
TIA
Mike
