I have the honeywell BDR91 thermostat which isn’t well, so have bought a hive - .
Looking at how it’s wired by the previous owner/installer, I’ve assumed the following
N- Hive N
Brown L - hive L
Brown loop L - also hive L ?????
Brown loop A - hive 1??
Earth in b - hive 3??
I’ve tried the above and boiler fires up, but no actual control of when the boiler fires from new hive thermostat. All is synced up hive wise, as in the receiver is saying that it’s telling the boiler to fire - but nothing.
As it’s late and cold, reverted back to old Honeywell one, works fine.
I’m lost! Any help appriciated
