6.4 Shifting Astro times for sunrise and sunset

The Astro times represent the varying sunrise and sunset times in the course of a
calendar year. The Astro shift function permits the individual adaptation of the factory-
computed sunrise and sunset times to your local conditions.
This shift is executed for all days throughout the year.
The maximum Astro time shift for the sunrise and sunset times is ± 1 hour and 59
minutes, in each case.
Info: This feature permits to accomodate 'brighter' and 'darker' installation sites.
Example 1:
The terrace of the house faces southwest where it will be light a little bit longer because
the sun sets in the west. The Astro sunset time can therefore be set a bit later (e.g. +
0:25 => the blind/shutter moves down 25 minutes later).
Example 2:
If the house is built on an east-facing slope, it will be dark there earlier than specified in
the Astro curve. The Astro sunset time can therefore be set a bit earlier (e.g. - 0:20 =>
the blind/shutter moves down 20 minutes earlier).
Example 3:
You want to watch the sunrise from your kitchen. To have the blind/shutter up by this
time, set the Astro sunrise time earlier (e.g. - 0:30=> the blind/shutter moves up 30
minutes earlier.
