Abstract
Disclosed is an HVAC (heating, ventilation and air-conditioning) system which comprises a fluid flow duct (), a fluid flow valve () which is arranged therein and has a valve body () in the fluid flow duct () and a valve motor () which moves the valve body (), a control circuit for activating the valve motor, a sensor () in the fluid flow duct () and an evaluation module for evaluating signals of the sensor. To produce an automated functional control, the following procedure is adopted: a first actuation signal is preset for the valve motor by the control circuit, and the actuation signal corresponds to a first setpoint position of the valve body (), registration of a first signal of the sensor () by the evaluation module, and determination of a functional diagnosis of the fluid flow valve on the basis of the first signal of the sensor.
