A bus system is disclosed which comprises a plurality of electrical and/or electronic components coupled to one another in terms of signaling via at least one bus line, said components including at least one master component and at least two slave components. At least one of the slave components functions as a master for one or a plurality of the further slave components for at least one operating parameter. There is additionally disclosed a method for controlling such a bus system comprising a plurality of electrical or electronic components coupled to one another in terms of signalling via at least one bus line, wherein at least one of the slave components operates as a master for one or a plurality of the further slave components for at least one operating parameter.

Bus system comprising a master component and a slave component that functions as master, and a method for controlling the same

A climate control device () with a heater (), a ventilation device (), and with an operating device (). The operating device includes an operating element () that can be switched to at least three different operating states. The operating element () has a first and a second electrical resistance device (), the first of which is associated with the heater () and the second of which is associated with the ventilation device. The electrical resistance of the two resistance devices () can be changed simultaneously by actuating the operating element ().

Air-conditioner comprising an operating device

A control circuit for a vehicle seat having at least one heating element and at least one fan is provided. The control circuit includes a two-pole switch having two synchronously actuated switch elements. The switch elements are operatively connected to the heating element and the fan to operate the heating element and the fan in a first operating mode wherein only the heating element is active, and a second operating mode wherein both the heating element and the fan are active. When two heating elements are employed, the two heating elements are connected in parallel by the switch elements in the first operating mode and are connected in series by the switch elements in the second operating mode.
