16.3 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 func-
tions:
◆
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 pro-
gramme
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.
The automatic dusk function via light sensor is only
executed once per day.
Mounting the light sensor
(see page 58, Automatic solar function)
The twilight time is recal-
culated every day based on
the geographical loca-
tion 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.
