5. Settings and functions

L In standard setting, an astronomical time switch switches
on during twilight and off during sunrise. Therefore, in
most applications, only one night switch-off (e.g. from
22:00 to 06:00) has to be programmed – and, if needed,
to be copied to all weekdays.
Astronomical time switches can be used for precise switching
of connected consumers based on sunrise and sunset. They
have an additional astro pulse, which can be used for roller
blinds and blinds control.
Furthermore, the astronomical time switched offer a twilight
range in three increments:
Sunset (civil twilight)
Twilight (nautical twilight)
Darkness (astronomical twilight)

ASTRO menu
In the ASTRO menu, astro times, total simulation, offset, astro
mode and position (locations) can be queried or changed.
Astro times
Display of the astro times (including the offset) for the
current day
Total simulation
Display of the switching response with a freely selectable
start date (the holiday program is not shown)
Offset
The offset (correction value) can be used to shift the
calculated astro times by +/– 120 min. This means that
the astro turn-on and turn-off times can be adapted to
local conditions (e.g. mountains, high buildings etc.) or to
personal requirements.
Astro mode
Evenings on, mornings off: At sunset it switches on, at
¾
sunrise it switches off (example: street lighting)

9:40
Twilight (nautical twilight):
¾
46
Twilight is when the centre of the sun is 6° below the
horizon
Darkness (astronomical twilight):
¾
The darkness setting, technically correct astronomical
twilight, is when the centre of the sun is 18° below
the horizon. Stars can be seen.
Location
Setting the location by selecting a town/city or via
¾
coordinates (latitude/longitude, time zone). By using
the Bluetooth OBELISK top3, up to 10 further towns/
cities (= favourites) can be added.
