With control inputs for light sensor and light switches For protection of lamps, the switching is done in zero point with soft on and soft off. In addition to the minimum brightness, even dimming can be adjusted, whereby at the same time, the duration of soft on and soft off changes. The adjusted values for minimum brightness are softened and ultimately switched off with the snooze function. With the children's rooms feature there is a slow brightening up to the set brightness level. Short control commands switch on / off, permanent control changes the brightness up to the maximum value. Suitable for ohmic, inductive and electronic loads which are automatically detected If the energy saving lamps is to be dimmed, then the function rotary switch must be set on ESL. This observes the special conditions associated with dimmable energy saving lamps. For example, the power up process is optimized and the dimming speed changes logarithmically and the switching of children's room is not possible.
