Hi
i had an engineer come out to diagnose a fault with my boiler which we thought was the 3 port valve not working, but was diagnosed to be the room stat not calling for the heating. on the advice of engineer he said change the stat as its cheap than them doing it at a cost of £140
I just wanted to know if i have wired it in correct as its still not calling for heating.
It is a Center EHE0200155 room stat
Earth to Earth Terminal
live goes in No1
neutral No3
and the other in No2
WHAT IS THE 3RD WIRE?
I tried swapping No2/No3 over but it trips electrics, so i guess above is correct.
on the diagram it shows between 1&4 that there is some kind of connection, Is this why its not calling for boiler??
I have enclosed some pics for reference, if someone can help that would be great.
Many Thanks
