REMOVE OLD THERMOSTAT

WARNING
Begin by turning off power to the heating circuit at
the main service panel.
Remove cover of old thermostat—cover normally
snaps off when pulled firmly from the bottom. If it
resists, check for a screw that locks the cover.
Loosen screws holding thermostat base to outlet box
and lift away.
Disconnect wires from old thermostat. As you
disconnect each wire, tape the end and label it with
the letter of the terminal designation to make reconnection
to new thermostat easier.
Check the old insulation for cracks, nicks or fraying,
and apply high quality plastic tape where necessary
for adequate insulation.
Retain the old thermostat for reference purposes
and until your new thermostat is functioning
smoothly.
