EnergyStar®settings for maximum cost savings
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 to use EnergyStar®program settings. We recom-
mend 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 RREESSEETTto 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 HHOOLLDDbutton three times to activate
this feature. This will control temperature and humidity to help protect your
house and possesions while you are away. (If this feature does not work,
contact your installer.)
