Label Description
Outside Air Control Fault
If the saved Control Mode is OA FLOW CTRL (see Controlling Outside Air Flow on
page 10), FAULT will display if Outside Air Flow is more than 15% off from the Outside
Air Flow Setpoint for longer than the Stroke Time (Seconds) (found under Configure >
Damper). This indicates that the damper is not moving properly.
Mixed Air Flow Fault
If the saved Control Mode is MAT CTRL (see Controlling Mixed Air Temperature on
page 10), FAULT will display if Mixed Air Temp is more than 15°F off from the Mixed
Air Temp Setpoint for longer than the Stroke Time (Seconds) (found under Configure >
Damper). This indicates that the damper is not moving properly.
Outside Air Flow Fault
FAULT = The calculation of the airflow based on the damper characterization data (see
Accessing the Damper Characterization Table on page 14) has differed from the
calculation using the current temperatures by more than the tolerance (20% difference
default) for longer than 10 minutes. Ensure that the equipment is in the same physical
condition as it was when Learning Mode was run. Learning Mode may need to be run
again and/or sensors re-calibrated.
Mixed Air Temp Low Limit
Control
ACTIVE = The damper is modulating toward closed to prevent freezing of the equipment
because the Mixed Air Temp is lower than the Low Temp Limit (found under Configure
> General).
INACTIVE = Either the Mixed Air Temp is higher than the Low Temp Limit, or Enable
Low Limit is set to OFF.
See the related low limit information in
Setting AFMS Parameters on page 4.
