INTRODUCTION OVERVIEW
INSTALLATION INSTRUCTIONS
| WARNING |
|
 |
ELECTRICAL SHOCK HAZARD—Turn off the 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 REQUIREDPackage includes Thermostat on base, thermostat cover, 2 “AAA” batteries, wiring labels, screws, and wall anchors. Tools needed: Drill with 3/16 bit, hammer, screwdriver, and putty.
TO REMOVE THE EXISTING THERMOSTAT
- Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate circuit breaker.
- Remove the cover of the old thermostat. This should expose the wires.
- Label the existing wires with the enclosed wire labels before removing wires.
- After labeling wires, remove wires from wire terminals.
- Remove existing thermostat base from wall.
- Refer to the following section for instructions on how to install this thermostat.
TO INSTALL THERMOSTATIMPORTANT: 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.
- Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate circuit breaker.
- Move the Function switch on the thermostat to Off.
- Remove the cover by inserting and twisting a coin or screwdriver in the slots on the top of the thermostat.
- Put the 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.
- With the base level, mark the placement of the mounting holes.
- Set thermostat base and cover away from the working area.
- Using a 3/16 drill bit, drill holes in the locations you have marked for mounting.
- Use a hammer to tap supplied anchors in mounting holes.
- Align the thermostat base with mounting holes and feed the control wires through the wire opening.
- Seal holes for wires behind the thermostat with non-flammable insulation or putty, or use a wall plate obtainable from local hardware or home building store.
- Use supplied screws to mount the thermostat base to the wall.
- Insert stripped, labeled wires in matching wire terminals by pressing on the corresponding terminal contact. See the “Wiring Diagrams” section of this manual.
CAUTION Make sure the exposed portion of wires does not touch other wires. - Gently tug wire to be sure of the proper connection. Double-check that each wire is connected to the proper terminal.
- Insert two “AAA” batteries into the battery holder. Verify that they are oriented as shown on the battery holder.
- Replace the cover on the thermostat by snapping it in place.
- Plug the unit in or turn on the power to the system at the main service panel.
- Test thermostat operation as described in the “Testing the Thermostat” section.

Low battery indicator
The programmable thermostats with battery backup have a low battery warning screen.
Low battery warningThe thermostat will display a low battery indication. The low battery warning will beflashing until batteries are replaced.
Power failure Indicator
The programmable thermostats with battery backup also will indicate the main power failure when the 24 VAC power from the room air conditioner is not present.Power failureThe thermostat will display a power failure indication (“PF”) on the screen.
Note: If “PF” is displayed, it means the 24 VAC power to the thermostat is lost.
Notes
Troubleshooting tips
| Problem | Solution |
| No Display | Check for 24 VAC at the thermostat and- batteries; the display is blank when 24 VAC is not present and batteries are bad. |
| System fan does not come on properly | Verify that the wiring is correct. |
| All thermostat buttons are inoperative | Verify that 24 VAC is present; the unit will not operate when 24 VAC is not present. |
| A thermostat turns on and off too frequently | Adjust temperature differential (see Configuration Mode – Setting Temperature Differential, Stage 1 and Stage 2 sections). |
| Program schedule activates at the wrong time | Check time (AM/PM) set on thermostat (see Programming). |
| The thermostat does not follow the program | Verify that it is in Program mode; PROG displays solid; check the time (AM/PM); check if in Hold mode (PROG flashing) |
| PROG flashes (in Hold mode) | Press the Hold button to remove from Hold mode |
| Fan runs continuously | Check Fan Auto/On switch. If set to ON position, fan will run continuously. |
| The room temperature is not correct | Verify that the 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. |
| The 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. |
