Hi all,
I recently bought a new digital room thermostat to replace the old one that was in my hall. The new one (Drayton Digistat 3) says that it replaces most standard room thermostats but I'm having problems with the wiring.
The wiring schematic for the new thermostat has -
1. Common
2. Heating satisfied
3. Call for heat
It also says that if the old thermostat used a neutral and/or earth supply, these should not be connected and should be safely isolated. The old one had a red wire(live), blue wire(neutral?) and yellow wire(switched live?) Does this mean I should only connect the live wire? If so does anyone know where I should connect it (common, heating satisfied or call for heat)?
My old thermostat was a honeywell. The red wire was connected to 1, blue to 2 and yellow to 3. I have checked and there is permanent live in the red wire and the yellow wire has some current running through but not as much as the red wire.
