Method for driving operating parameter of fan, particularly seat ventilation device of seating system of motor car by serial protocol, involves controlling control unit of fan by serial protocol

摘要

The method involves controlling a control unit (5) of a fan (7) by a serial protocol, where the serial protocol is transmitted by a supply line (3) of the fan. The operating parameter includes a speed or direction of rotation, where the operating parameters of the fan are changed according to a predetermined function profile. An independent claim is also included for a ventilation device, particularly a seat ventilation device of a seating system of a motor vehicle with supply voltage.
