AUTO CHANGEOVER

Auto Changeover is a feature used in climates where both
air conditioning and heating are used on the same day.
The Auto setting appears only if the thermostat is set up
for Auto Changeover by your heating and air conditioning
dealer. In some installations, Auto may be the only system
selection.
The following pages in this Auto Changeover section
provide an example of how to change both the cool and
heat temperature settings when the system is set to Auto.
When you are adjusting the temperature setting, if
"Cool" or "Heat" appear in the display, the
temperature setting of the opposite mode is also being
adjusted. The thermostat automatically keeps the cool
and heat temperature settings three degrees apart (called
deadband). This three-degree deadband is not adjustable.
