Program Schedule

You can program four time periods each day, with different settings for
weekdays and weekends. We recommend the pre-set settings (shown in the
table below), since they can reduce your heating/cooling expenses.
Wake - Set to the time you
awaken and the temperature you
want during the morning, until
you leave for the day.
Leave - Set to the time you leave
home and the temperature you
want while you are away (usually
an energy-saving level).
Return - Set to the time you
return home and the temperature
you want during the evening,
until bedtime.
Sleep - Set to the time you go to bed and the temperature you want overnight
(usually an energy-saving level).
NOTE: Leave and Return periods can be canceled on weekends.
