Hive dual channel (I'm confused?!)

[cold lwinteruk]

I'm looking to replace my existing Honeywell system with a dual channel hive mini.

Thanks

You have a Y plan system, the programmer (controller as you refer to it) is a straight swap, although someone has used the green/yellow as a live wire, instead of the usual earth - which is not permitted, but perhaps you can put some brown sleeving or brown insulation tape on it.

The Honeywell thermostat (dial) can either be set to maximum and the Hive will take over, or you can join the 2 wires that are in 1 and 3 and safely terminate 2 in a connector block inside the wiring center.

Thanks, I've uploaded a clearer picture of the wiring centre.

To confirm, I'd join the 2 brown wires in 1 with the earth cable in 3.
Then terminate the three blue wires into a terminal block?

Thanks

Nope, not what I said.

Join the 2 wires from the thermostat- the temperature dial on the wall together, there is no earth wire in there which I can see. The 3 wires you have are brown (live in) and blue and black, number 2 is neutral (so likely the blue wire) and black if in terminal 3 of the thermostat will join with the brown in terminal 1 of the thermostat.

DO NOT JOIN ANY LIVE CONDUCTORS UP WITH EARTH UNLESS YOU WANT TO START CAUSING ISSUES?

No, stick the grey wire from the controller into this terminal block (where the black is now - so it is connected to the white)..

And remove the cable to the thermostat completely.
Then as you say, the Hive back plate is (more or less) a straight swap.

Edit, didn't see @CBW post above - this is an alternative suggestion!

Thanks! I'll do that. Seems pretty straightforward

@RandomGrinch @CBW Thanks for your help! Everything seems to be working so far. Pairing was straight forward and the boiler is working. Appreciate it.

Well done, and thanks for letting us know the outcome

...but blimey, 25.5 degrees!
