Honeywell to hive

[Ritchiep33]

Hi

i am wanting to swap the current honey will system attached to my combi boiler with a new hive one

whilst I am not an expert, I am competent so believe I can swap this the same as I would a light switch or plug fitting - am I right that in the images attached, the wires would line up like that?

Honeywell being the one attached to a wall, hive being held with:

N- blue
L- brown
1- black
3- grey
Earth to the right

wanted to ask and double check!

Yes, pretty much it. Although, depending on the boiler, might need to swap black and grey wires.

Thanks Chris - how would I know about the swapping of the grey and black? Is there an easy way to check this? Or I guess, what is the risk of them being round the wrong way??? (As in what is the potential worst case for black and grey being round the wrong way and we turn on the boiler? Is it boiler breaking territory or switch it off and swap them and all will be fine?)

Yes, pretty much it. Although, depending on the boiler, might need to swap black and grey wires.

If you’re worried, just wire it the same as Honeywell, which is swapping black and grey.

Understood - thank you!
