Replacing Honeywell wireless receiver with a Hive

[oxfordmark]

Hi all

I have a combo boiler. A Nest controls our radiators and the Honeywell our Underfloor heating. So the cabling is spurred from the boiler already.

I want to replace the Honeywell wireless receiver for a Hive.

This is the current wiring for the Honeywell. Is it a straight forward change?

Would be great full of some guidance.

Yes, it is straightforward (assuming a single channel Hive).

The Blue wire in N on the Honeywell, would move to N on the Hive receiver backplate.
The Brown wire in L to L.
The Black wire in B to terminal 3.
The short Brown link wire would connect L and terminal 1.
The Green/Yellow wire would ideally park in the Hives earth terminal.

Although, out of interest, do you mind if I ask why you chose to go with a Hive, instead of another Nest and keep the controls unified under one app?

The cost, was cheaper getting the Hive. Mainly use Alex to control all our house smart things.

When you say single channel, do you mean only heating button on the receiver?

Yep, also known as Hive for combi.

Thanks, that's interesting to know. Some consider Hive to be a rather basic stat compared to Nest i.e. not supporting opentherm, but it does have a few functions that Nest doesn't.
And I guess having both thermostats controlled by one app, isn't everything

Yes the receiver only has a fire button.

I have a smart meter so get gas usage via them various apps

Thanks for your help, will let you know how it goes.
