Hi folks I'm about to change my Honeywell cm907 thermostat to a hive heating thermostat,I have a Worcester combi boiler. In the Honeywell receiver beside the boiler,there live and neutral which I'm fine with,there are also two other wires,one goes into "A" and one into "B" which connections in the in the hive receiver do I connect these two....it says 4 is unused so that leaves 1,2 and 3 Any help would be appreciated
CM907 is a programmable thermostat and only has 3 terminals A, B and C. A = Live supply B = Live Return (switched) there is no neutral?
Thanks for replying Looking in the receiver it has,a neutral and live connection which I'm assuming is permanent then a block marked ABC with wires in A and B. I need to know which terminals in the hive receiver do existing A and B go to Thanks
Yeah sorry I should have said that,it is BDR91,just need to figure out the A and B connection from it to the corresponding on the hive Thanks again for the help
This is the wiring for a single channel Hive: I take it only needs L, N, common (1), and Heating On (3) connected? Just leave out the Heating off (2)?
