Hi, hoping someone can help. This is a question already answered 7 years ago here ://www.diynot.com/diy/threads/honeywell-cmt927-wireless-thermostat-ideal-icos-he24.185434/ although struggling to reconcile that with the wiring diagrams I have.
As the title says, I have an ideal he24 combi boiler (just moved house, not the boiler I would choose) and want to fit a honeywell cm927.
Below is the he24 wiring diagram
And below is the bdr91 relay box wiring diagram :
Surely I want to connect L1 and L2 on the boiler to A and B on the bdr91 (and of course the N/L as per specified)?
Please advise
