Auto Changeover
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.
Press until screen
displays “Auto”
Note:
The Auto system setting
may not appear, depending
on how your thermostat was
installed.
