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). |
This thermostat is pre-set with energy-saving program settings. We recommend these settings, since they can reduce your heating/cooling expenses by as much as 33%. (See below to adjust times and temperatures of each time period.)
Note: You can press CANCEL PERIOD to eliminate any unwanted time period.
Note: Press FAN to customize fan settings for any time period.
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 time you set. When the timer expires, the program schedule will resume and set the temperature to the level you've programmed for the current time period.
To cancel the temporary setting at any time, press CANCEL (or SCHED). The program schedule will resume.
Press HOLD to permanently adjust the temperature. This will turn off the program schedule.
Whatever temperature you set will be maintained 24 hours a day until you manually change it or press CANCEL (or SCHED) to cancel "Hold" and resume the program schedule.
This feature can suspend the program schedule for extended periods of time.
Press or to set the temperature you want, then press or to set the time of day you want the schedule to resume when you return.
Press HOLD twice, then press or to select the number of days.
Whatever temperature you set will be maintained 24 hours a day for the number of days you select. After this number of days have elapsed, the previously programmed schedule will resume at the time you set.
If you return earlier than expected, press CANCEL (or SCHED) to cancel "Hold" and resume the program schedule.
Auto Changeover: When set to Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature.
Adaptive Intelligent Recovery: This feature allows the thermostat to "learn" how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example: Set the Wake time to 6 am, and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6. The message "Recovery" is displayed when the system is activated before a scheduled time period.
Compressor Protection: This feature forces the compressor to wait a few minutes before restarting, to prevent equipment damage. During the wait time, the message "Wait" is displayed on screen.
To prevent tampering, the screen can be partially or fully locked.
When partially locked, the screen displays SCREEN LOCKED for several seconds if a locked key is pressed. To unlock the screen, press any unlocked key while SCREEN LOCKED appears on the screen.
When the screen is fully locked, no keys function. To lock or unlock the screen, see advanced function 0670.
Press SCREEN to lock the screen for cleaning.
The screen will remain locked for 30 seconds so you can clean the screen without changing any settings.
After 30 seconds, press DONE to resume normal operation, or press SCREEN again if you require more time for cleaning.
Note: Do not spray any liquid directly on the thermostat. Spray liquids onto a cloth, then use the damp cloth to clean the screen. Use water or household glass cleaner. Avoid abrasive cleansers.
Select models can display the current indoor humidity level.
(If an optional outdoor sensor is installed, the outdoor temperature is shown instead of the humidity level. Press MORE to display the humidity level.)
Select models allow you to decrease summer humidity.
The thermostat monitors humidity. When humidity increases, the thermostat runs the air conditioner longer to reduce humidity (up to 3°F below your cooling temperature setting).
Press MORE until the humidity screen is displayed, then press or to set the desired humidity level.
Press DONE to save and exit, or press CANCEL to exit without saving changes.
Batteries are optional (to provide backup power) if your thermostat was wired to run on AC power when installed.
