BDR91 to Hive Switch

[tomludlow]

Hi all,

Hope you can help,

Trying to change an old BDR91 to a Hive Mini system on a Logic Combi 35 Boiler. The wiring diagram doesn't seem to help. Currently the N and first L are going to a fused switch below the boiler. The Second L, A (Gray) and B (Black) are going up to the boiler.

I assume N and L1 go in N and L on the next, but can't work out the rest. Is L2 for slot 1, A for 3 and B for 4?

Thanks in advance for any help!

Tom

'N' on BDR91 to the 'N' terminal on the Hive Mini backplate

Both 'L' s on the BDR91, to the one 'L' terminal on Hve.

Grey 'A' wire on BDR91, to the '1 - Common' terminal on Hive.

Black 'B' wire on BDR91, to the '3 - Heating On' terminal on Hive.

I am sure I seen another post somewhere about how to wire up a Hive

I really appreciate your help, its working perfectly!
