Honeywell cm907 change to hive heating

Stephen smith · 21 Oct 2016

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
