Hi all,
Just a quick sense check if I can. I have a Heatrae sadia electromax with a tp5000 two wired programmable room thermostat. Im looking at the potential of moving to a wiser smart system and specifically wiring the wiser hub.
Am I correct in thinking I need to run new wire to connect ‘room stat L’ on my boiler to terminal 4 on the wiser backplate, ‘room stat R’ to terminal 3 and also a wire to boiler neutral and boiler permanent live (N and L on the wiser backplate)?
Any suggestions as to which N and L on the boiler end?
Currently boiler works as expected and is wired matching the wiring diagram.
Wiring diagrams attached below.
Thanks in advance
