DESCRIPTION
1.3. AstroDIM – autonomous dimming without
external control
AstroDIM is designed for dimming without any external
control wiring. Therefore, AstroDIM helps to save energy
and reduce light pollution, even if only a power line is
available. In AstroDIM operation, the ECG executes a
preset dimming profi le, which can be reconfi gured via the
3DIM Tool. The autonomous dimming is regulated by an
integrated timer (no real-time clock), which adjusts the
dimming profi le according to the previous night (operation
from switch-on to switch-off). With the 3DIM Tool, it is
possible to activate two independent dim levels.
