Step 5. Label Old Thermostat Wires
1.
As you disconnect each wire, use the enclosed wire
labels to wrap a wire label around each wire that
matches the letter designation. Do not allow the
wires to fall into the wall opening after the wires
are disconnected.
2.
Remove any remaining parts of the old thermostat
from the wall.
When connecting the wires to the new
thermostat, refer to the wire labels. Do not
connect wires to your new thermostat based
on the color of the wire.
