Sun protection and twilight function
Info: The delays of 2 respectively 15 minutes are necessary to prevent premature
movements of the blind/shutter in the event of short-time variations in brightness.
The sun protection function can be deactivated by depressing the
key briefly.
The twilight function
The twilight function lowers the blind/shutter automatically when it gets dark. As soon as
the brightness falls below the preset value, the moon symbol starts flashing. 4 minutes
later, the blind/shutter is lowered down the limit stop.
The twilight function is activated 2 hours before the Astro sunset time only to prevent the
blind/shutter from being moved down inadvertently during the day when the sensor is
covered up.
If the twilight function is to be executed in conjunction with switching times, these must
be programmed with Astro values.
In this case, the twilight function replaces the Astro sunset time.
Switching times without Astro component are executed at the programmed time inde-
pendent of brightness.
