Only shown if ISU176 = 2 or for Heat Pump systems
with 2 stages of Auxiliary Heat.

Default varies based on types of heating.
If backlight is on continuously, it is low-intensity.
Light changes to full brightness after pressing any
key.
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.
Set to 0 in areas that do not follow daylight savings
time.
