Abstract

A control is functional to perform a method of determining a maximum desired airflow for each of a plurality of zones in a multi-zone HVAC system, and an expected airflow to those zones. In part, these determinations are based upon an algorithm that calculates the relative size of the ducts leading to each of the zones. The expected and maximum airflows are compared for each of the zones, and if any zone has an expected airflow that exceeds its maximum airflow, certain steps are taken to reduce airflow to that zone.
