Identify Wires
3
If any wires are not attached to your old thermostat or are
attached to a terminal marked C or C1, they will not be
connected to your new thermostat. Wrap the bare metal
end of each of these wires with electrical tape, so it can-
not touch and short other wires.
Do not use non-connected
wires.
Do not use C or C1 wires.
Identify and label each wire.
IGNORE WIRE COLORS:
Use terminal screw
designations to identify
wires.

Disconnect wires and remove the old wallplate only after
all wires are labeled. Wrap the wires around a pencil to
prevent them from falling though the wall opening.
