Wiring Drayton Wiser

[Suzy!!!]

Hi, has anyone got a photo of a wired up backplate for a Drayton Wiser one channel thermostat. I am trying to replace an old salus which has a non standard backplate.

Probably better posting photos of your existing setup, we can tell you which wires go where.

Old wiring

It’s unusual to see 2 wires in NO and nothing in the COM (Common). What type of system is it? Eg Combi boiler, zone valves?

That is what confused me. It is an ideal discovery + combi boiler.

It's probably knackered so someone has just joined the wires together to get the heating working.
On your new controller:-
Blue to N
Brown to L
Black to 1
Grey to 3

Brilliant. That is working perfectly now. Ready for the cold weather when it arrives.
