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 by as much as 33%.
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.

Auto changeover (heat/cool)

Auto Changeover is a feature used in climates where both air conditioning and heating are used on the same day. When the system is set to Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature. Heat and cool settings must be at least 3 degrees apart. The thermostat will automatically adjust settings to maintain this 3-degree separation (called “deadband”). The 3-degree separation between heating and cooling set temperatures is fixed, and cannot be changed.

  1. Press system button until screen displays “Auto”.

Note : The Auto system setting may not appear, depending on how your thermostat was installed

Built-in compressor protection

Damage can occur if the compressor is restarted too soon after shutdown. This feature forces the compressor to wait for a few minutes before restarting. During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump). When the safe wait time has elapsed, the message stops flashing and the compressor turns on.
