Abstract
A volumetric flow controller for air conditioning and ventilation systems for displacing a control flap that is adjustably supported in the interior of a flow channel includes a differential pressure sensor for measuring a pressure difference prevailing in the flow channel. A control unit displaces the control flap depending on the pressure measured by the pressure sensor for adjusting a target volumetric flow in the flow channel. A first operating element is for selecting one of a plurality of parameters, in particular of control and/or configuration parameters. A second operating element is for adjusting the value of the respective selected parameter. A display is for displaying the currently set value of the respective selected parameter. The first operating element is a push button, a touch-sensitive switch, a touch-sensitive control panel or a contactless operating element for advancing the respective parameter displayed in the display.
