A multi-zoned HVAC system includes a control for independently determining the amount of airflow delivered to each zone within the HVAC system. The control determines nominal zone airflow and continuous fan airflow levels for each zone based upon a user selected fan airflow level and the relative size of each zone in the HVAC system. The control determines the desired system airflow for the entire system once the continuous fan airflow levels for each zone are determined. The HVAC system provides a continuous fan airflow to each zone independently of the continuous fan airflow delivered to any other zone and irrespective of the relative size difference of the zones.
