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 until Set Schedule is displayed.
2. Press to set your weekday Wake time (Mon-Fri), then press SET.
3. Press to set the temperature for this time period, then press SET.
4. Set time and temperature for the next time period (Leave). Repeat steps 2 and 3 for each weekday time period.
5. press SET to set weekend time periods (Sat-Sun), then press RUN to save & exit.
   Note: Make sure the thermostat is set to the system you want to program (Heat or Cool).
   Note: To cancel an unwanted time period (except Wake), press and hold + HOLD for 4 seconds while in the Set Schedule mode.

Program schedule override (temporary)

Press 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.

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 to cancel “Hold” and resume the program schedule.

Built-in compressor protection

This feature helps prevent damage to the compressor in the air conditioning or heat pump system.
Damage can occur if the compressor is restarted too soon after shutdown.This feature forces the compressor to wait for a few minutes before restarting.
During the wait time, the message Cool On (or Heat On if you have a heat pump) will flash on the display. 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 BATT 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 1 minute, the time and day will not have to be reset. All other settings are permanently stored in memory,and do not require battery power.
