Honeywell T4 Pro 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).
NOTE: To temporarily or permanently override any of the above program schedules, see page 4.
