Description
The circuit is not running, and cannot run without intervention.
Description
The circuit has been shutdown on a latching diagnostic.
The circuit is manually locked out by Manual Override Control at the Front Panel.
Unlike other Manual Overrides these locks are not terminated when the Manual
Overrides Time expires, and are persisted through power cycles.They can only be
cleared at the Front Panel.
Description
The given circuit is currently being inhibited from starting (and running), but may
be allowed to start if the inhibiting or diagnostic condition is cleared.
All compressors on the circuit are currently locked out and unable to start.
The suction pressure dropped below a pressure threshold. See the IOM for more
details.
Compressors on the circuit are inhibited to remove frost on the coil.
Description
The circuit is not currently running but can be expected to start at any moment
given that the proper conditions are satisfied.
The EXVs are performing a calibration cycle. A calibration is performed whenever
the unit controller is power cycled, or when the unit controller is running, the
circuit is off, and it has been at least EXV Recalibration Time since the last EXV
Calibration was executed.

Night Purge and Occupancy Status = Occupied
Pre Cool Active = True
