INSTALLATION INSTRUCTIONS

WARNING

ELECTRICAL SHOCK HAZARD — Turn off power by unplugging the unit or by removing the fuse or switching the appropriate circuit breaker to the OFF position before removing the existing thermostat. Failure to do so could result in risk of electric shock.

PACKAGE CONTENTS/TOOLS REQUIRED:

Package includes:

• Thermostat base
• Thermostat cover
• Wiring labels
• Screws
• Wall anchors

Tools needed:

• Drill with 3/16″ bit
• Hammer
• Screwdriver
• Putty

TO REMOVE EXISTING THERMOSTAT

1. Turn off power to 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

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.

2. Remove the cover by inserting and twisting a coin or screwdriver in the slots on the top of the thermostat.

3. Put thermostat base against the wall where you plan to mount it. Make sure wires will feed through the wire opening in the base of the thermostat.

4. With the base level, mark the placement of the mounting holes.

5. Set thermostat base and cover away from working area.

6. Using a 3/16″ drill bit, drill holes in the locations you have marked for mounting.

7. Use a hammer to tap supplied anchors in mounting holes.

8. Align thermostat base with mounting holes and feed the control wires through the wire opening.

9. Seal hole for wires behind thermostat with nonflammable insulation or putty, or use a wall plate obtainable from a local hardware or home building store.

10. Use supplied screws to mount thermostat base to wall.

11. Insert stripped, labeled wires in matching wire terminals by pressing on the corresponding terminal contact. See the “Wiring Diagrams” section of this manual.
    NOTICE
    Make sure exposed portion of wires do not touch other wires.

12. Gently tug wire to be sure of proper connection. Double check that each wire is connected to the proper terminal.

13. Replace cover on thermostat by snapping it in place.

14. Plug the unit in or turn on power to the system at the main service panel.

15. Test thermostat operation.

TROUBLESHOOTING TIPS

present
System fan does not come on properly| Verify that wiring is correct.
All thermostat buttons are inoperative| Verify that 24 VAC is present; unit will not operate when 24 VAC is not present.
Thermostat turns on and off too frequently| Adjust temperature differential (see Configuration Mode – Setting Temperature Differential, Stage 1, Stage 2, and Stage 3 section).
Fan runs continuously| Check fan selection. If set to ON, fan will run.
Room temperature is not correct| Verify that wall hole is plugged with putty or insulation to prevent airflow from the wall cavity. Adjust Temperature Offset (see Configuration Mode – Room temperature offset section).
Compressor doesn’t run or turn off immediately when changing function or setting| There is a 3 minute time delay and a 3 minute minimum run time for the compressor when it turns on/off.
Fan doesn’t run or turn off immediately when changing function or setting| This is normal. On some models, the fan may have a minimum run time/off time delay.
Problem not listed above| Press the Reset button once to reset the thermostat microprocessor.
