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.
