Hi
We got a Camray 5 Oil Boiler with a timer and I like to replace it with a remote room thermostat. I know the boiler needs to be on water and heating at the same time, so I just link my heating wire and hot water wire together, they are no 3 and 4 then I have left on the time on number 2 live and on number 1 neutral, as I only got an in at one end I assume for my heating on and hot water on of my receiver of the wireless thermostat and what do I put on the other one live or neutral?
Any info appreciated

Thermostat will go between wiring going to 4 and the terminal 4. Leave 3 where it is.

However can't find that thermostat, so not sure if it needs 230 volt power or not.

Thanks, of course, I was just stupid, sometimes I can not see what is in front of my eyes, this is a wireless thermostat and the picture is for the receiver which has its own adapter power supply.
