Manual - (Set Supply air VAV smoke ctrl.air flow setp. to the
desired airflow setpoint)
b.
Set Supply air VAV balancing command to Balancing. The airflow
setpoint is set to the appropriate value based on the Supply air VAV
balancing mode, the Supply air VAV balancing state is set to Balancing
and the control program will be overridden for balancing operation.
c.
Allow time to let airflows stabilize. The automation station will modulate
dampers to achieve the defined airflow setpoint.
d.
Measure airflow externally with a capture hood or other device.
e.
Set Supply air VAV air volume flow at hood with the value determined
from the previous step. The control program will calculate and update
Supply air VAV calc. flow coefficient.
f.
Set Supply air VAV balancing command to Calibrate. The value of
Supply air VAV calc. flow coefficient will be set to Supply air VAV flow
coefficient.
g.
(Optional) - Repeat parts d through f if the calculated airflow does not
meet the specified accuracy.
h.
Set Supply air VAV balancing command to Record. All Recorded
parameters will be updated.
i.
(Optional) - Set Supply air VAV balancing mode to a different mode and
repeat parts
b through h if required to confirm accuracy at a different
airflow setpoint.
j.
Set Supply air VAV balancing command to Balanced. The Supply air
VAV balancing state is set to Balanced and the control program will
return to normal operation.
