Program Schedule
You can program four time periods each day, with different settings for
weekdays and weekends. We recommend the pre-sets (shown in the table
below), since they can reduce your heating/cooling expenses.
Wake - Set to the time you wake up and
the temperature you want during the
morning, until you leave for the day.
Away - Set to the time you leave home
and the temperature you want while
you are away (usually an energy-saving
level).
Home - 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).
