Hi All,

I'm having trouble wiring up my Hive receiver to my Worcester Bosch 37CDi Combi. I'm replacing a Honeywell BDR91 wireless receiver which only had 4x wires going to it L, N, A & B.

I thought it would be simple enough to wire up the Hive receiver but I'm getting nowhere!

I've attached some photos to show the old BDR91 wiring and the diagram shown in the Hive instructions. If anyone could help I'd really appreciate it.

L and N are obvious and I believe A and B simply Go to 1 and 3. The other terminals are left empty

obviously make sure you turn the power off to the stat wires before undoing them
