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

Press until screen 
displays “Auto”

Note: 

The Auto system setting 

may not appear, depending on 
how your thermostat was installed.
