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.
