WIRING AND CONFIGURATION OF THE ECG
The AstroDIM dimming profi le can be confi gured with just
one or two dim levels.
Every night, the ECG-integrated timer measures the
operat ing time of the ECG (time between switch-on and
switch-off). Based on the measured operating times of
the previous nights, the AstroDIM algorithm calculates
the operating time of the coming night. Figure 26 shows
four exemplary dimming profi les, displaying how the
AstroDIM algorithm adapts the dimming to the actual
length of the night, centering the dimming profi le around
the half operating time.
For correct operation and special cases, please see
chapter 5.4. (FAQ).
