ideal eco esprit 24: replacing boss therm br1 with Hive

[OrangeRoad]

Hello all,

I have a Boss Therm BR1 receiver with a BRTRF wireless thermostat, and it is currently working fine with my Ideal Eco Esprit 24 boiler.

Assuming the existing wiring is correct (since it functions properly), would it be correct to say that the only rewiring work I need to do to switch to Hive would be on the receiver only? Asking this because I am not very skilled and I am assessing the difficulty of doing this all by myself.

I have yet to open the faceplate of BR1 but I assume it'd be very similar/ identical to what it's shown here: https://www.diynot.com/diy/threads/boss-br1-to-hive-active-heating-wiring.569055/ - although I am not 100% sure on their wiring in the picture?

Regards

Wiring can vary.
If you're not confident, show us a picture of the wiring behind the BR1, and we should be able to give some clearer guidance.

Looking at the instructions, it seems it is on/off control, but looking at the diagrams it is not clear as to what voltage. The old thermostat seems to be volt free

, the link you show it was not wired as volt free, so you need a picture of yours, not some random picture.

Don’t assume anything

Apologies - life has been really busy and I just didn’t have any time to work on the house.

These are the pictures of the wiring.

I’ve uploaded the pictures above - sorry for the late response!

That's ok!

As it is, your assumptions were correct!
The wiring (to the single channel Hive) does exactly match that which is shown in the linked thread.

The only difference - the link wire would be red in your case (modified above!).

However, current regs don't allow the use of a green/yellow wire for a switched live (as you have). At the minimum, the green/yellow wire should be oversleeved in brown, to denote it as a switched live.

@RandomGrinch is correct, wire colours are no longer permitted, don't think they ever were? Not since 2008 at least, can't remember 2004 book.

As to if it needs correcting, unlikely, but do want to at least put brown tape around it.
