Installing your thermostat
3 Label the wires.
Use the supplied sticky tags to label
each wire as you disconnect it. Label
wires according to the old thermostat
terminal designations, not by wire color.
Note:
If no tag matches a terminal
designation, write the appropriate
letter on a blank sticky tag.
