The group object is enabled if the Send sun azimuth and elevation parameter is set to On request or On request and
automatically/cyclically in the GPS coordinates and sun data – GPS sun data parameter window.
The object is used to send the current sun elevation on the KNX bus.
The azimuth can also be sent as a 4-byte value via object 13 if the receiving device can process it.
15
The group object is enabled if the Send sun azimuth and elevation parameter is set to On request or On request and
automatically/cyclically in the GPS coordinates and sun data – GPS sun data parameter window.
The object is used to trigger sending of the sun azimuth and elevation on the bus.
16
The group object is enabled if the Send sunrise and sunset times parameter is set to On request or On request and
automatically/cyclically in the GPS coordinates and sun data – GPS sun data parameter window.
The object is used to send the current sunrise time on the KNX bus.
17
The group object is enabled if the Send sunrise and sunset times parameter is set to On request or On request and
automatically/cyclically in the GPS coordinates and sun data – GPS sun data parameter window.
The object is used to send the current sunset time on the KNX bus.

Note
During polar nights or polar days, the sun angle values in the polar regions are fixed as follows:
 Elevation/zenith = 0°
 Azimuth = south azimuth in the northern hemisphere/north azimuth in the southern hemisphere
