BDR91 Issue?
Posted: Wed Nov 01, 2023 1:12 pm
Hi all - my first post here and apologies if this is a well-worn question.
Our heating works some of the time just as it should - either on a timer set by the Honeywell digital display, or when I turn the valve on an individual rad. The water heating works perfectly too.
However, I've noticed that sometimes the heating doesn't come on - the screen is showing the right setting, and the BDR91 for the heating has a green light, but the boiler doesn't fire. Does this mean probably the BDR91 is playing up (or maybe the wiring between it and the boiler I guess?) as the fault seems intermittent. IF I fire the hot water up at the same time then suddenly the heating works, I presume as the boiler is now on.
I'll try and reset the BDR and pair it with the system again, but I can't see that being the issue as it seems to be receiving the command, just not always passing it on to the boiler!
