18.3 Automatic dusk function; brief description

The automatic dusk function causes the roller shutters to
close automatically to the lower end point or configured
ventilation position.
You can choose between two automatic dusk
functions:
◆ Automatic dusk function with Astro programme
= switching time mode [ ASTRO ]
◆ Automatic dusk function with light sensor
= switching time mode [ SENSOR ]
Automatic dusk function with Astro
programme
The twilight time is recalcu-
lated every day based on the
geographical location and
the current date (defined by
the configured postcode).
Configure a custom offset period
An offset can be configured between -60 and +60 minutes
in order to customise the calculated dusk time to your
personal preferences. 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.
Automatic dusk function with connected
light sensor
At twilight, the roller shut-
ters will lower to the lower
end limit or configured
ventilation position after
approx. 10 seconds. The
roller shutters will open
again once the configured
opening time is reached
or in the event of a manual
command.
The required twilight limit is configurable.
NOTE
The automatic dusk function via light sensor is only
executed once per day.
