BALANCING
Balancing Ducted Supply – Pressure Independent and Dependent Airflow Control
NOTE: If a ducted return or return mixing box is used, a PSC, ECM Constant Torque or ECM Constant Flow (preferred) can be used.
Step 1: If return mixing box is used, turn primary air off. If ducted return, proceed directly to Step 2.
Step 2: Set FFU to desired airflow. See Airflow Setpoint section to determine initial setpoint.
Step 3:
Confirm airflow using flow hood and adjust speed controller as required.
Step 4: Power up the primary airflow control device. (Ductwork should have been previously balanced).
Step 5: Measure airflow using flow hood and compare against scheduled flow. Adjust speed controller as necessary to achieve
design airflow.
