18. Automatic darkness function
The automatic darkness function causes the roller shutters to
close automatically. It is possible to select between two different
automatic darkness functions using:
◆
the "astro" program
◆
the connected light sensor
Both functions can be linked to a timer periods. This is then
interpreted by the controller as "at the latest xx:xx hours", see
page 24.
Automatic darkness
function with "Astro"
program
The twilight time is recalculated every day based on the
geographical location and the current date (defined by the
configured postcode).
The calculated time can then be customised to personal
preferences by means of an offset between
-60
and
+60
minutes.
This means that it is not necessary to continuously readjust the
closing time throughout the year.
a light sensor is not used for this function.
