Organizing Your Schedule
Your thermostat can be set for four time periods (Wake, Leave, Return, and Sleep) for the
weekday schedule (Monday through Friday), and four time periods for the weekend schedule
(Saturday and Sunday). Without additional programming, your thermostat follows the same
preprogrammed schedule for both weekdays and weekends (see Table 1).
WAKE
Choose the time you want your heating or cooling system to start to
reach your comfort temperature after the SLEEP period.
How? Consider the time required to reach your comfort level. Adjust the
Wake time to earlier when you know it will take the system longer to
reach your comfort temperature.
LEAVE
Choose the time you want your heating or cooling system to start an
energy-saving mode while you are away at work or school.
How? Set the Leave temperature lower during heating season, and
higher during cooling season.

Minimum Off-Timing
CAUTION
Your thermostat comes equipped with a
minimum off-timer. At certain times during
cooling, the system will not start up again for
at least five minutes after it turns off (compressor is off and can’t be heard). This occurs
when you change the SYSTEM switch
position while the compressor is off or when
you change the temperature setting, causing
the compressor to turn off. The minimum offtimer is also triggered during power interruption and power restoration. You will know the
minimum off time is in effect by a flashing
or
on the display.
Equipment Damage Hazard.
Can cause permanent damage to
the compressor or other equipment.
To avoid possible equipment damage,
do not operate cooling when outside
temperature is below 50°F (10°C).
See equipment manufacturer instructions. To avoid possible compressor
damage, allow the compressor to
remain off for five minutes before
restarting.
