4.2.4.6.3 Astro and random function
Astro function
The astro function allows the control of a lighting or shading system depending on sunrise and
sunset and a limit time. The astro function can be activated separately for each switching time.
The panel calculates the time of the sunrise and sunset (astro time) automatically according to
the local geographic position (geographic co-ordinates). The setting of the co-ordinates is the
precondition for correct functioning and is carried out in the "Timer switch" parameter node in
the "Location data" parameter group and applies in the same way to all the timer switch channels.
A special dialog in the ETS plug-in simplifies the determination and configuration of the
geographic location co-ordinates.
When the astro function is activated, the time set in the ETS plug-in or directly on the panel as
the limit time. Whether the limit time affects sunrise or sunset is evaluated by the device according
to the set time. Times between 00:00 and 11:59 are evaluated as sunrise and times
between 12:00 and 23:59 as sunset.
An astro function usually affects lighting (e.g. exterior lighting) or shading (e.g. roller shutters).
The behaviour of the panel when processing the astro switching times varies according to these
applications. The parameter "Channel affects" in the parameter node of a timer switch channel
defines the astro behaviour - irrespective of the data format of the communication object of the
channel - as follows...
- "Lighting" setting:
Sunrise (switching times 0:00 - 11:59): if sunrise occurs before the set time (for example in
the summer months), then, at sunrise, the switching time command (e.g. external lighting
OFF) is sent to the bus. If sunrise occurs later (for example during the winter months), then
the switching time command is sent to the bus at the set time at the latest. When a switching
time is set, the appropriate time is overwritten with "At the latest" in the ETS plug-in.
Sunset (switching times 12:00 - 23:59): if sunset occurs after the set time (for example in
the summer months), then the switching time command (e.g. external lighting ON) is sent
to the bus at sunset. If sunset occurs earlier (for example during the winter months), then
the switching time command is sent to the bus at the set time at the latest. When a switching
time is set, the appropriate time is overwritten with "Not before" in the ETS plug-in.
- "Shading" setting:
Sunrise (switching times 00:00 - 11:59): if sunrise occurs after the set time (for example in
the winter months), then the switching time command (e.g. roller shutters UP) is only sent
to the bus at sunrise. If sunrise occurs earlier (for example during the summer months),
then the switching time command is sent to the bus at the set time at the latest. When a
switching time is set, the appropriate time is overwritten with "Not before" in the ETS plugin.
Sunset (switching times 12:00 - 23:59): if sunset occurs before the set time (for example in
the winter months), then the switching time command (e.g. roller shutter DOWN) is sent directly
to the bus at sunset. If sunset occurs later (for example during the summer months),
then the switching time command is sent to the bus at the set time at the latest. When a
switching time is set, the appropriate time is overwritten with "At the latest" in the ETS plugin.
i Depending on the geographic position of the location, the astro times for sunrise and sunset
will vary by several hours. If a switching time with an active astro function affects another
switching time of the timer switch channel, then the astro function is not executed.
Example: a switching time is set to 17:00, astro function active (seasonal sunset between
16:00 and 22:00), an additional switching time is set to 19:00 -> In this case, the second
time (19:00) would be affected by the astro function, meaning that it would be deactivated
for the affected switching time(s). The same would apply, if both switching times in the example
had the astro function active.
