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 outside 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 the outside of the thermostat cover

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. See Replacing
Wiring Labels table (below) on other side for old and new label identification.
4. After labeling wires, remove wires from wire terminals.
5. Remove existing thermostat base from wall.
6. Refer to the following section for instructions on how to install this thermostat.
ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing

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. Seal hole for wires behind thermostat with non-flammable insulation or putty.
13. Set the Gas/Electric switch to electric or gas/oil, and heat pump jumper to NON-HP or HP.
14. Set the temperature scale jumper to Fahrenheit or Celsius.
15. Replace cover on thermostat by snapping it in place.
