摘要

The ventilation device (4) has a heat exchanger (3) for heat transfer between air exchange streams. An input device is provided, on which a user make requirements for the operation of the ventilation device. A control unit determines the carbon dioxide-content of the air in the building interior and regulates the operation of the ventilation device. An independent claim is also included for a control method for a ventilation device.
