Abstract
An operating control device for adjusting the power of a heating device has a rotary knob that has an off position in which said rotary knob is deactivated, and a working position into which said knob can be brought to adjust the power. The working position is predetermined by a lock-in position, and the rotary knob can be rotated over a working angle of a rotation range in at least one direction of rotation from the working position counter to a counterforce that rises as the angle of rotation increases. The operating control device can detect the angle of rotation and uses a control system of the operating control device for adjusting the power. The control system is configured in such a manner that the power is adjusted more rapidly as the angle of rotation increases.
