Note: The Auto system setting

Auto Changeover is a feature used in
climates where both air conditioning
Auto
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
MCR29531
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.
