Which terminal should the brown wire be connected to the RadioThermostat CT80? The original thermostat was wired as depicted:
The brown wire is connected to terminal E (not F).
As I understand it:
- BRN => ? Terminal CT80 Radio thermostat
- YEL => Y Terminal CT 80
- GRN => G Terminal CT 80
- WHT => W Terminal CT 80
- RED => R Terminal CT 80
- BLU => C Terminal CT 80
- ORANGE => O Terminal CT 80
As I understand it, the brown why controls the Emergency heat relay. Not one of the seven diagrams has an E-Wire.
- Is it possible to select one of the seven schemes based on the first photo?
- Where terminal should the brown 'E' be wired in the CT80?
