Measured (calibrated) airflow:
AV110 (R)
Range: 0 to 20000 CFM (0 to 9440 l/s).
Current active airflow setpoint.
AI350 (R) Airflow Setpoint is not displayed when Damper Override is Open or Closed.
Range: 0 to 10000 CFM (0 to 4720 l/s).
Force damper to selected position during balancing.
0 - None: No damper override. Damper under normal control.
1 - Minimum: Force damper to maintain minimum airflow setpoint.
2 - Max. cool: Force damper to maintain maximum cooling airflow setpoint.
MV172 (R/W)
3 - Close: Force damper closed.
4 - Reheat: Force damper to maintain maximum reheat airflow setpoint.
5 - Open: Force damper fully open.
Choices: None, Minimum, Max. cool, Close, Reheat and Open.
Measured value will be used to update calibration Offset and ensure mea-
sured Airflow level matches Balometer reading.
