Claim Text:
1. A control unit for a functional device of a motor vehicle, comprising: a holding element; a rotary adjuster that is mounted in a rotatable manner on the holding element, to rotate in a direction of rotation, the rotary adjuster comprising three encoding elements; a latching device to produce a plurality of latching positions for the rotary adjuster along the direction of rotation; and a detecting device to produce a digital output signal for two of the three encoding elements, to produce an analog output signal for a third of the three encoding elements, to detect a current latching position of the rotary adjuster and to detect an absolute angle of rotation between the rotary adjuster and the holding element, the absolute angle of rotation being an absolute angle of rotation between at least two of the latching positions, the current latching position and the absolute angle of rotation being detected based on an encoding of the encoding elements.
