Bdr91 to single channel hive

[Sanjay29]

I have attached the pic of the wiring
I am about to connect hive soon Fingers crossed
i have removed the bridging wire between the 2 live terminals...as advised previously. Thanks
I have not connected the hive yet
The system is all working fine at the moment
question is....when i do make the change on to hive and if things go wrong can i reconnect my bdr91 back in and turn the boiler on and off by connecting the A and B wires..?.just need a safety net in this cold weather ....
Thanks

Probably not. To replicate what you have now A is also linked to L. So you would need to connect A&B and also L. Sorry I can't be more specific without knowing what the other end of each of the wires is connected to.

If you wire it up properly then there's no reason why the Hive won't work. If it doesn't, then simply reinstate the BDR exactly as it is, and continue as you are now.
