• Press the or button until the desired temperature setpoint displays.
• The new temperature setpoint is automatically saved in memory.

Starting the thermostat

CAUTION! Do not use air conditioning when the outdoor temperature is below 50 degrees. This can damage your air conditioning system and cause personal injuries.

1. Move the Fan Auto/On switch to the Auto position. On position runs indoor fan continuously.
2. Move the Function switch to Cool or Heat, depending on the season.

Testing the thermostat

Once the thermostat is installed, it should be thoroughly tested.
CAUTION! Do not use air conditioning when the outdoor temperature is below 50 degrees. This can damage your air conditioning system and cause personal injuries.
Note: Before testing the thermostat, move the Fan Auto/On switch to the Auto position.
Cool Test

1. Slide Function switch to Cool position. Cool mode screen is displayed.
2. Adjust set temperature so it is 5 degrees below room temperature.
3. Air conditioning should come on within a few seconds.
4. Adjust the set temperature so it is 2 degrees above the room temperature and the A/C should turn off. Note: There is a 3-minute time delay and a 3 minute minimum run time for the compressor when it turns on/off. (On some models, the fan may also have a 3 minute minimum run time/off time delay.)

Heat Test

1. Slide Function switch to Heat position. Heat mode screen is displayed.
2. Adjust set temperature so it is 5 degrees above room temperature.
3. Heat should come on within a few seconds.
4. Adjust the set temperature so it is 2 degrees below the room temperature and the heat should turn off. Note: There is a 3 minute time delay and a 3 minute minimum run time for the compressor when it turns on/off. (On some models, the fan may also have a 3 minute minimum run time/off time delay).
   Note: “Quick Heat Recovery” is activated each time the thermostat is switched from Off or Cool modes to Heat mode. Electric heaters are energized until the thermostat set point is reached. Heat pump operation will resume at next call for heat (heat pump only).

Fan Test

1. Slide Fan Auto/On switch to On position.
2. Indoor fan turns on.
3. Slide Fan Auto/On switch to Auto position.
4. Indoor fan turns off.

5. Press the or button to set the current day of the week. Note: Sliding the Function switch to Cool or Heat positions will lock the values into memory. You may also press the Hold button to enter your programming schedule.

Programming

Program Overview
The programmable thermostat has four periods (MORN, DAY, EVE, NITE) that are customizable for each day of the week. Each period will have a set time, heat temperature and cool temperature. The thermostat monitors the day and time, while maintaining the specific conditions that you have chosen for each period in your program.
Note: Operation being set will blink in the display.

1. Place the Function switch in the Off position.
2. Press the Hold button in for 6 seconds.
3. Press the Hold button 3 times. DAY (01–07) and PROG is displayed.
4. Press the or button to change the day you want to program (01 = Monday, 02 = Tuesday, etc.).
5. Press the Hold button to advance to the next parameter.
   Note: You can always press the Mode button to return to the previous parameter.
   Period is displayed (MORN, DAY, EVE, NITE).
6. Press the or button to change period of day. The display should blink the period of the day.
7. Press the Hold button to advance to the next parameter.
   Set time is displayed.
8. Press the or button to adjust hours. Press the Hold button once, and then press the or buttons to adjust minutes.
9. Press the Hold button to advance to the next screen parameter. Note: Transitions required after 11:59 PM must be programmed in the next day’s MORN period.
   1. Heat temperature is displayed (60°F to 85°F)
10. Press the or button to adjust heat set temperature.
11. Press the Hold button to advance to the next screen.
    Cool temperature is displayed (60°F to 85°F)
12. Press the or button to adjust cool set temperature.
13. Press the Hold button to advance to the next screen.
    Repeat steps 1–13 to program each day of the week individually or follow the instructions below to program every day the same as Monday. When programming is complete, slide the Function switch to Heat or Cool to exit Programming Mode.

Repeat Programming
Once the entire Monday (Day 01) schedule is set, the following procedure can be used to copy the Monday schedule for every day of the week.
After the complete Monday schedule is set (see Programming, above), you will be at the “Day” screen:

1. Press the button once. Day 01 screen displays.
2. Press the button and hold for 2 seconds. The days of the week stop flashing, locking the settings into memory. Once the schedule is locked in, you can go through each day and make any required changes. This feature speeds up the programming of the standard weekday/weekend schedule.
3. Slide the Function switch to Heat or Cool to exit Programming Mode.

Factory preprogramming

The programmable thermostat comes preprogrammed with the following schedule:

Use the following personal program schedule to record your settings:

Low battery indicator

The programmable thermostats with battery backup have a low battery warning screen. Please note that the low battery warning will not display while in a programming mode or settings menu. The following are the only locations where the low battery warning may occur.

• Low battery warning, Off mode
  The thermostat will display a low battery indication. The display will toggle between the normal display and the low battery indication.
• Low battery warning, Cool mode
  The thermostat will display a low battery indication. The display will toggle between the normal Cool mode display or program Cool mode display and the low battery indication.
• Low battery warning, Heat mode
  The thermostat will display a low battery indication. The display will toggle between the normal Heat mode display or program Heat mode display and the low battery indication.

Combination failure (power failure & low battery)

The programmable thermostats with battery backup also will indicate a combination failure; that is, both a low battery condition as well as a power failure condition. After the power is restored, the following may be indicated:

• Combination failure, Off mode
  The thermostat will display a low battery indication, as well as a power failure indication (“12:00”). The display will toggle between the low battery screen and the “12:00” screen.
• Combination failure, Cool mode
  The thermostat will display a low battery indication, as well as a power failure indication (“12:00”). The display will toggle between the low battery screen and the “12:00” screen (Non-Program Cool Mode Shown).
• Combination failure, Heat mode
  The thermostat will display a low battery indication, as well as a power failure indication (“12:00”). The display will toggle between the low battery screen and the “12:00” screen (Non-Program Heat Mode Shown).

Troubleshooting tips

Problem	Solution
No Display	Check for 24 VAC; display is blank when 24 VAC is not 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.
