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.
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.
I have a Wiser Thermostat kit2 2 channel,and i try to change my old wifi room china thermostat with this Wiser kit2, but i don't know where I must to connect 2 (page 7 from pdf ) wire from my old thermostat to WiserHub ?My gas boiler is Arca Pixel 31FC. The pdf of my boiler i have attached !
My old thermostat this 2 wire is connected to the COM and NO (normally OPEN) pin.

I have the same scheme that on photo above.. L,N and COM and NO(normally OPEN)
