Issue:
He has a Tracker 12 / CCP III setup and he is getting alarms from the VAVs for "Flow sensor fail". When will VAV UCM give a diagnostic of flow sensor fail?
Resolution:
The VAV UCM will fail its flow sensor if the flow goes below 5% or above 110% of the nominal rating of the box. This is an auto-reset diagnostic and will disappear if the flow value comes back into the correct range.
