Replace EP4002 with nest - advice

Andrew Whitehurst · 20 Oct 2021

Can anybody please advise me on where the wires I currently have would go on a Nest Heat Link. Mainly the grey wire which I believe is the signal wire to the combi boiler for central heating, the red and yellow wires are from the battery powered thermostat.

Are you sure it’s not grey and yellow for the room stat? If you’re unsure, I think it’s just a parking terminal, so linking them up in a connector block in the Nest would do exactly the same.
