Auto
Auto Changeover allows user to choose heat, cool, off
or auto. When set to Auto the thermostat will
automatically choose heat or cool based on room
temperature and heat/cool set points. Manual
changeover allows the user to manually toggle
between heat, cool and off.

Only shown if ISU300 = 0. The deadband indicates the
minimum number of degrees that are allowed between
the heat and cool settings when in auto changeover.
For example, if the deadband is set to 3°F and the cool
setpoint is 75°F the warmest heat setpoint allowed
would be 72°F.
