The Standard Display
The Standard Display is the default display that
appears if no other display function is selected.
The Standard Display shows the box temperature
and setpoint. The box temperature is that
measured by the controlling sensor, usually the
return air sensor. The box temperature in Figure
55 is 35.8 F with a 35 F setpoint.

cooling. If the unit was heating the arrow would
