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

Press HOLD to permanently adjust
the temperature. This will override
the temperature settings for all time
periods.
The “Hold” feature turns off the program
schedule and allows you to adjust the
thermostat manually, as needed.
Whatever temperature you set will
be maintained 24 hours a day, until
you manually change it, or press RUN
SCHEDULE to cancel “Hold” and resume
the programmed schedule.
NOTE: Make sure the thermostat is set
to the system you want to control (heat,
cool or auto).
