Honeywell receiver to hive

[confused_penguin]

Hi

I currently have a Honeywell BDR91 receiver attached to my combi boiler, but no thermostat, so don't believe the receiver is doing anything - I just control the boiler directly using the front panel.

I have bought a Hive heating system, and am looking to install it myself.

I assume I can just replace the honeywell receiver with the hive receiver? Or will the fact I'm currently not using a thermostat mean that won't work?

How do I change the wires from one to the other?

Current wiring:

Instruction manual for hive:

I've looked at other posts (e.g. here) but can't work it out.

Any help appreciated!

How do I change the wires from one to the other?

The Blue wire in N on the BDR91 would connect to N on the single channel Hive backplate.
The Brown in L to L.
The Green/Yellow wire in B isn't an earth, it is a switched live to the boiler. This should be oversleeved in Brown and connected to terminal 3.
The short Brown link wire between L and A on the BDR91, would move to connect L and terminal 1 on the Hive.

But as you say...

Or will the fact I'm currently not using a thermostat mean that won't work?

It is possible that the old BDR91 is linked out somewhere else.
What boiler do you have, and how do you get it to start heating?

Thank you!

It's a vaillant ecoTEC plus 832 combi. I control it using the front panel on the boiler - I.e. either on, off, or timed, for timed I use the pins on the clock to set on/off times.

The white flex on the left of the bottom picture is the flex that goes to the box in the post above

Thanks.
Does the boiler still fire manually, if the BDR91 is removed from its backplate?
Take care if you try this, as there will likely be mains voltages on the partially exposed terminals.

Likely linked out at the boiler on 24v connection, unless the receiver uses the override
