Hi guys,
I'm replacing my old room thermostat with a digital one and i'm not to sure about wiring it up.
I've removed the old one and i now have 4 wires sticking from the wall,
RED
BLUE
YELLOW
and EARTH.
They are all dead until the heating comes on and then the RED wire is live.
The new thermostat only as 3 terminals marked,
NO
COM
NC
Can anybody please tell me how to wire it up,i'm totally stumped.
Thanks for all replies,madsey
