Select the fan setting

 

Press the FAN button to select Auto or On. In “Auto” mode (the most commonly used setting), the fan runs only when the heating or cooling system is on. If set to “On,” the fan runs continuously. Use this setting for improved air circulation, or for more efficient air cleaning.

Select the system setting

• Heat: The thermostat controls only the heating system.
• Cool: The thermostat controls only the cooling system.
•  Off: Heating and cooling systems are off.

CAUTION: EQUIPMENT DAMAGE HAZARD. To prevent possible compressor damage, do not operate the cooling system when the outdoor temperature is below 50°F (10°C).

Save money by setting program schedules

It’s easy to program your system for maximum energy savings. You can program four time periods each day, with different settings for weekdays and weekends

 

• Set to the time you awaken and the temperature you want during the morning, until you leave for the day.
• Set to the time you leave home and the temperature you want while you are away (usually an energy-saving level).
• Set to the time you return home and the temperature you want during the evening, until bedtime.
• Set to the time you go to bed and the temperature you want overnight (usually an energy-saving level)

EnergyStar® settings for maximum cost savings
This thermostat is pre-set to use EnergyStar® program settings. We recommend these settings since they can reduce your heating/cooling expenses by as much as 33%. (See next page to adjust times and temperatures of each time period.)

To adjust program schedules

1. Press SET CLOCK/DAY/SCHEDULE, then SET SCHEDULE.
2. Press or to set your weekday Wake time (Mon-Fri), then press NEXT.
3. Press or to set the temperature for this time period, then press NEXT.
4. Set time and temperature for the next time period (Leave). Repeat steps 2 and 3 for each weekday time period.
5. Press NEXT to set weekend time periods (Sat-Sun), then press DONE to save & exit.

Note: Make sure the thermostat is set to the system you want to program (Heat or Cool).
Note: You can press CANCEL PERIOD to eliminate unwanted time periods (except Wake).

Program schedule override (temporary)

 

Press or to immediately adjust the temperature. This will temporarily override the temperature setting for the current time period. The new temperature will be maintained only until the next programmed time period begins (see page 10). For example, if you want to turn up the heat early in the morning, it will automatically be lowered later, when you leave for the day. To cancel the temporary setting at any time, press RUN SCHEDULE

Program schedule override (permanent)

 

Press HOLD to permanently adjust the temperature. This will override the temperature settings for all time periods. The “Hold” feature turns off the program schedule and allows you to adjust the thermostat manually, as needed. Whatever temperature you set will be maintained 24 hours a day, until you manually change it, or press RUN SCHEDULE to cancel “Hold” and resume the programmed schedule.

Built-in compressor protection

This feature helps prevent damage to the compressor in your air conditioning or heat pump system. Damage can occur if the compressor is re-started too soon after shutdown. This feature forces the compressor to wait for a few minutes before restarting. During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump). When the safe wait time has elapsed, the message stops flashing and the compressor turns on.

Battery replacement

Install fresh batteries immediately when the REPLACE BATTERY warning begins flashing. The warning flashes about two months before the batteries are depleted. Even if the warning does not appear, you should replace batteries once a year, or before leaving home for more than a month. If batteries are inserted within two minutes, the time and day will not have to be reset. All other settings are permanently stored in memory and do not require battery power

In case of difficulty
If you have difficulty with your thermostat, please try the suggestions below. Most problems can be corrected quickly and easily. The display is blank • Make sure fresh AA alkaline batteries are correctly installed
(see page 15).

Temperature settings do not change

• Heat: 40° to 90°F (4.5° to 32°C).
• Cool: 50° to 99°F (10° to 37°C).

To restore Energy Star® default settings
Follow these steps to restore Energy Star default settings (see page 10):

1. Press SET CLOCK/DAY/SCHEDULE.
2. Press SET SCHEDULE.
3. Press DONE and NEXT at the same time for 4 seconds.
