If you forgot to label the wires off your old thermostat or if the labels you have don't match a name on the common list, we need to determine what wires you have.

For labels not on the common list consult the detailed list of wire name s and their function.

For missing lables it will be necessary for you to consult the detailed sysytem schematics provided, and to trace the witres you have back to the HVAC unit and find their labels there.
