Airflow Setpoint BFC
Step 1: Determine if BFC will be controlled using local control, BAS analog voltage signal, or BACnet. The control mode can be
confirmed by observing the cycling status readout on the LCD.
NOTE: The control hierarchy is BACnet > BAS > Local. The control mode is based on the highest level of control provided.
Step 2: For Local or BACnet control, determine the setpoint from the appropriate airflow formula for your model in the tables below.
If BFC is being controlled by BAS analog voltage signal, refer to "ECMSC Airflow Setpoint" section for proper input voltage (Note
this will be 2X the VDC value shown in the tables).
Set-point (ECM%) ranges from 0% - 100%
