In that case I humbly apologise. Many thanks for the advice, it really is much appreciated.

Sorry to sort of hijack this thread but I have a similar problem. I currently have a Honeywell ST9400C which has wires to L, N, 3 & 4. I want to upgrade to a Hive V3, is it just a case of swapping like for like. I don't currently have any thermostats just TRV's on all the radiators.
