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 automati-
cally 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.
