Description  

If the saved Control Mode is MAT CTRL (see Controlling Mixed Air Temperature on  

page 11), 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.  

Mixed Air Flow Fault  

FAULT = The calculation of the airflow based on the damper characterization data (see  

Accessing the Damper Characterization Table on page 15) 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.  

Outside Air Flow Fault  

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).  

Mixed Air Temp Low Limit  

Control  

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 5.
