Important Safety Information
• Always turn off the thermostat before installing, removing, cleaning, or servicing; turn off the power at the main
power source by unscrewing fuse or switching off circuit breaker
• Do not switch to “Cool” if room temperature is below 50°F (10°C); this could damage your A/C system and cause
injury
• Do not install on voltages higher than 30 VAC
• All wiring must conform to local and national building and electrical codes and ordinances
• While cleaning, do not get soap directly on thermostat switches or LCD readout; only use a damp cloth with a mild
soap to wipe outside of thermostat cover

To Remove Existing Thermostat
ELECTRICAL SHOCK HAZARD
– Turn off power at the main service panel by removing the fuse
or switching the appropriate circuit breaker to the OFF position before removing the existing
thermostat.
1. Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate circuit
breaker.
2. Remove cover of old thermostat. This should expose the wires.
3. Label the existing wires with the enclosed wire labels before removing wires.
4. After labeling wires, remove wires from wire terminals.
5. Remove existing thermostat base from wall.

To Install Thermostat
ELECTRICAL SHOCK HAZARD
– Turn off power at the main service panel by removing the fuse
or switching the appropriate circuit breaker to the OFF position before removing the existing
thermostat.
IMPORTANT:
Thermostat installation must conform to local and national building and electrical codes and
ordinances.
Note:
Mount the thermostat about five feet above the floor. Do not mount the thermostat on an outside
wall, in direct sunlight, behind a door, or in an area affected by a vent or duct.
1. Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate circuit
breaker. Move the
Cool/OFF/Heat
switch to
OFF
.
2. Move the
FAN AUTO/ON
switch to
AUTO
.
3. To remove cover, insert and twist a coin or screwdriver in the slots on the top of the thermostat.
4. Put thermostat base against the wall where you plan to mount it (Be sure wires will feed through the wire opening
in the base of the thermostat).
5. Mark the placement of the mounting holes.
6. Set thermostat base and cover away from working area.
7. Using a 3/16” drill bit, drill holes in the places you have marked for mounting.
8. Use a hammer to tap supplied anchors into mounting holes.
9. Align thermostat base with mounting holes and feed the control wires through wire opening.
10. Use supplied screws to mount thermostat base to wall.
CAUTION!
:
Be sure exposed portion of wires does not touch other wires.
11. Tighten screws on terminal block. Gently tug wire to be sure of proper connection. Double check that each wire
is connected to the proper terminal.
12. Set the
fan jumper
to
electric
or
gas/oil
, and heat pump jumper to
NON-HP
or
HP
.
13. Replace cover on thermostat by snapping it in place.
14. Turn on power to the system at the main service panel.
