Hive Mini Wiring Help Please

[sutclifg]

Good evening,

I purchased a single channel Mini Hive to replace my Center wireless thermostat on my combi boiler, below is a photo of the current wiring and wiring diagram for the Center but I'm unsure which terminals on the Hive I should connect the grey and black wires currently in A & B

Many Thanks in advance

Why did you choose the hive?

I did look at the nest but don’t have access to power where I want to mount the thermostat, also got a decent deal on the hive with latest 20% off on eBay

The hive is just a dumb on/off control that can be remote controlled over the internet. It won't save you money like a modulating control will.

A to 1 and B to 3.
