Hi All,
I want to replace my wired Honeywell wired programmer ST9400c and dial thermostat T6360B to a Hive dual channel system and would be grateful if anyone can confirm a few things beforehand please? I have read multiple threads on this from here, but mine doesn't correspond
I have uploaded a few pictures of the wiring of the current Honeywell ST9400c and the T6360B as it is currently fitted. Looking at previous posts and STEM's really helpful advice and comments on these I was hoping it would be a simple cutover on the backplate from ST9400C to Hive dual controller using the N-L-1-2-3-4 as per previous answers supplied on here, but the current programmer backplate wiring looks different to other posts and can see the following from the picture supplied:
a. There are 3 x connections to the L (live), I was only expecting 1.
b. There is nothing in 1 (HW OFF) and 2 (CH OFF) and was expecting these to be there (or at least HW OFF in 1) like other ST9400C examples seen on here?
c. There are feeds and connections to HW ON (3) and HW OFF (4) as expected though and expect they just cut over like for like?
Do I just wire up like for like from the Honeywell ST9400c (1 x N, 3 x L, HW On (4) and CH ON (3) into the dual channel HIVE Controller and plug in and all will be ok? If so what happens to the lack/absence of HW Off (1)?
Also in terms of the T6360B Thermostat do I just remove/leave the dial thermostat off/on the wall and just terminate the wires as follows:
a. Connector 3 (Switched Live) and Connector 1 (CH ON) combine to not leave the Thermometer open circuit and allow the HIVE programmer to then do the temperature control thereafter?
b. Remove and isolate the Connector 2 (Neutral) into a chock block or leave as is if remaining on the wall?
I have looked at what should be the Honeywell 10 way block in the airing/tank cupboard labelled "Honeywell" and its a dogs dinner (See picture), so have avoided trying to trace the Thermometer from corridor to airing cupboard to disconnect the Thermostat from there, unless anyone can tell me from the picture which wires to remove (I was expecting to see a simple terminal block 4 and 5 to be removed and then a link strap inserted).
Any guidance is appreciated on this.
