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.
Tip:
If no tag matches a
terminal designation, write the
appropriate letter on a blank
sticky tag.
4 Remove old wallplate.
Remove the old wallplate from
the wall after all wires have been
labeled and disconnected.
Tip: Wrap the wires around
a pencil to prevent them from
falling back into the wall.
