Figure4. Main Status Screen
The Main Status screen displays current operating
information. This screen includes:
•
Header Line: The header line alternates between the
job name and unit tag. If there are active alarms, the
number of active alarms is displayed instead of the
job information.

Unit Status Line: System startup information and unit
operation status appears here.
•
Four Quadrants: These quadrants have information
that may change every three (3) seconds, depending
on options and sensors installed:
•
Upper Left Quadrant: Displays the current value of
the primary control variable. For example, this could
be supply air temperature, room air temperature,
return air temperature, or coil leaving temperature
•
Upper Right Quadrant: Displays all temperature and
humidity values that pertain to the air handler
•
Lower Left Quadrant: Displays the set-point that
corresponds to the primary control variable in the
upper left quadrant and may rotate through other set-
points
