I am trying to replace the hard wired t stat in the house. The old one is wired using 4 ply wiring, green and yellow(obvious) conected to earth, yellow not used, red goes to terminal '1', blue to terminal '3'. Problem i have is new thermostat is marked OFF (heat satisfied, call for cooling). ON (call for heat). COM (common/switched live from time control) and N (not required)
My question is, which colour wire goes to which terminal or what does terminal 1 and 3 relate to??
Cheers, Jon
PS, the Thermostat im trying to fit is a Drayton digistat 30002
