• Freeze Protection Feature: Protects pipes from freezing! If the room temperature drops to 40 ° F, the thermostat
automatically turns on the heat; the thermostat must be in the Heat position; works even if the batteries are dead
• Built-in Compressor Protection for Air Conditioners: To protect the A/C's compressor, there is a 5-minute
delay between the system turning off and the A/C starting
• System Customization: Choose Fahrenheit or Celsius display; three available temperature differential
settings
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.
6. Refer to the following section for instructions on how to install this thermostat.
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.
Replacing Wiring Labels
Replace the old labels with the enclosed new labels:
Old New
F, G G Fan control relay
O O Cool active reversing valve
B B Heat active reversing valve
Y, Y6 Y Cooling control
H, W, 4 W Heating control
C Transformer, common side
M, 4, RH, RS, R R Transformer, hot side
If the C terminal is the cooling control, connect to Y terminal; if it is the
C Y or C
common side of the transformer, connect to C terminal
