VAV Box cooling air K factor used to calculate the flow value.
Refer to Appendix K for specific values
0 < range ≤ 10000
K = Airflow / (Pv)
1/2
Pv: differential flow press (InWc)
Airflow: airflow (CFM)
Notes:
The K factor must be configured before starting the optional two
point airflow balancing procedure.
The K factor is obtained from the terminal box manufacturer.
Do not change the K value after the VAV box has been balanced
using the two point method.
Never set the K value to invalid or zero.

Occupancy sensor operation
1: UnoccupiedCleaningCrew, When scheduled to be unoccupied
and the occupancy sensor is active, switch to standby for the
comfort of the cleaning crew.
2: ConferenceRoom, When scheduled to be unoccupied stay
unoccupied independent of the occupancy sensor activity. During
scheduled occupancy, occupancy sensor changes mode between
standby and occupied.
3: UnoccupiedTenant, When scheduled to be unoccupied and the
occupancy sensor is active, switch to occupied for the comfort of
the tenant.
Notes
If an occupancy sensor is configured and the space is scheduled
for occupied and the occupancy sensor is inactive, the mode
switches to standby.
Manual override commands have priority over the schedule and
the occupancy sensor.
Occupancy Sensor Behavior
1 – No occupancy detected (inactive)
0 – Occupancy detected (active)
Standby mode occupancy interpretation.
0: Standby considered unoccupied for Fan operation and auxiliary
output.
1: Standby considered occupied for Fan operation and auxiliary
output.
