Wiring terminals
TERMINAL OUTPUTS AND WIRING DIAGRAMS
Does wire color correspond to the thermostat terminals?
Wire color does not always correspond to the thermostat letters. A white wire may be attached to the “W”
terminal on the old thermostat, or it may be attached to a different terminal with a different letter. Be sure
to take a photo of the old thermostat that shows the wire colors and terminal letters before labeling and
removing any wires.
