ABSTRACT:
In an air conditioning economizer system outdoor air intake is reduced automatically by a control device based on a shut-off control setting for a measured outdoor air quality. A geographical location associated with the air conditioning economizer system is received (S2) in the control device. The control device defines automatically (S3) the shut-off control setting based on the geographical location. Thus, the air conditioning economizer system is adapted specifically for a geographic location and its climate zone, without the requirement for installing or operating personnel to determine a shut-off control setting for a specific climate zone and/or select a corresponding operating range.
