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 sen-
sors 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.
