Auto changeover
This feature is 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.
Note: System setting function 0300
controls Auto changeover. See “Manual/
Auto Changeover” on page 56.
