Wiring smart thermostat

Jeff212

Anyone know the correct way to wire from my old thermostat to the smart set up?

Isolate the mains and confirm with a tester

Ditch the short Brown jumper

Brown L to common

Blue N to P1 (or P2 or P3)

Yellow/Green to NO This should have a brown sleeve on it to indicate (switched) live

Martin666

Yes, but tidy up the ends so that you cannot see any exposed conductor

Jeff212

Like so? Excluding the brown sleeve currently.

Many thanks! All working fine.
