Identify Wires
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 cannot 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.
