It’s easy to program your system for maximum energy savings. You can program four
time periods each day, with different settings for each day.
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 next page to adjust times and temperatures of each time period.)

Special features
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.
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.
Flashing message: Reminder to replace filter or UV lamp. After replacement, press
RESET to reactivate the alert timer.
Southern Away Dehumidification: Your system may be programmed to control
humidity while your house is vacant during the humid season. Before you leave the
house, press the HOLD button three times to activate this feature. This will control
temperature and humidity to help protect your house and possessions while you are
away. (If this feature does not work, contact your installer.)
