BDR91 to Hive2 help please???

[Topsy11]

Hi,
I currently have a Baxi duotec combi boiler with a BDR91 receiver. I’ve actually got 2 as it has 2 zones.
I’m a little confused with the wiring and would appreciate any help please.
I’ve attached a photo of the current wiring if anyone could have a look and advise me please.
Thank you

You need two single channel Hive's one to replace each of the BDR's.

From the 3 core cable, the:

Blue wire in BDR N = Hive N
Brown wire in BDR L = Hive L
Black wire in BDR B = Hive 'Heating on' 3

Use one of the brown links to join Hive terminals L and 1 'Common' together

Repeat for the second BDR and second Hive.

Spot on, thanks

I’ve got 2 receivers and thermostats, so will give it a go tomorrow.
