Call a qualified electrician.
m
Disconnect wirea from old thermostat or
sub-
U base. As you disconnect each wire, use mask-
ing tape to label it with the old terminal designation.
If there are only two wires, they don’t need to be
3
labeled. Keep the wires from falling back into the
wall by wrapping them around a pencil, as shown
Two extra wires?
If
you are replacing a Honeywell
Chronotherm
thermostat, you may find two wires that go to the
clock terminals on the
Chronotherm thermostat
wiring
wallplate. Disconnect the wires, and wrap
them separately, using electrical tape. Do not wrap
them together. Place the wires where they will not
interfere with the operation of the new thermostat.
Record the colors and terminal designation labels
of the rest of the wires.
