Installation of Drayton wiser smart thermostat

[will windell]

Hello all,

Looking for some advice. I currently have a Drayton digistat thermostat and I want to replace it with a Drayton wiser Smart thermostat kit 1 (combi boiler). The current setup is like this:

so the black wire is the 230V live and the brown wire is the C-wire.

the wiser kit one channel diagram is here:

Can someone please advise which wires I put where?

Thanks

You’ll need to confirm if that grey wire is a neutral wire before you start anything. Then if it’s confirmed, and providing the brown common is a permanent live, then place the grey wire in neutral, brown to live, link live to com and black to on.

Sorry, forgot to mention, that earth wire needs some green & yellow sleeving on it.
