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
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 to cancel temporary setting and resume program schedule Press to temporarily adjust temperature Note: Make sure the thermostat is set to the system you want to control (heat or cool). |
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 to permanently adjust temperature
Press to cancel “Hold” setting and resume program schedule Press to permanently adjust temperature Heat Note: Make sure the thermostat is set to the system you want to control (heat or cool). |
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
Press down and pull to remove
Insert fresh AA alkaline batteries, then reinstall battery holder
|
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. |
