Auto Changeover is a feature used in cli-
mates where both air conditioning and heat-
ing are used on the same day. When the sys-
tem is set to Auto, the thermostat automati-
cally 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.
Press until screen
displays “Auto”
Note: The Auto system setting
may not appear, depending on
how your thermostat was installed.
