Abstract

A method of maintaining a position of an airflow-direction control element 16 of a HVAC system, comprising the steps of, a] determining a position of at least one movable member of an airflow-direction control mechanism of the HVAC system; and b] calculating whether the movable member is at a target position associated with a required position of the airflow-direction control element, and if not, activating an airflow-direction-controller actuator of the HVAC system to effect a change in the position of the movable member thereby bringing the airflow-direction control element to or towards the said required position. A HVAC system suitable for implementing such a method is also provided and capable of improving the overall efficiency of operation.
