WARNING
This thermostat is a line voltage control (120 Volts to
240 Volts.) Do not install it if you are not completely
familiar with house wiring. If handled improperly,
there can be risk of a 120 Volt to 240 Volt electric
shock hazard, which may cause serious injury or
death.
Carefully unpack your new thermostat. To avoid
damage to the sensing element, do NOT remove
the thermostat cover until wiring has been completed.
Save packages of screws, instructions, receipt and
proof-of-purchase.

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
3-1/4
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.
