Commissioning of the KNX Function via DCA (from ETS5)
Lat. [dd.dd][+ = North, − = South]
■
Options:
The parameter is used to set the geographic latitude for the location of the device (90° North
to 90° South)
This setting is important for the astro function. The entry is made in decimal degrees, i.e.,
the angular minutes are specified as number of decimal places.
One degree corresponds to 60 minutes.
Example:
51° 14' 53" North (51 degrees, 14 minutes and 53 seconds North) = +51.25 decimal degrees
Example of calculation:
53' (seconds) divided by 60 = 0.88' (minutes)
14' (minutes) + 0.88' (minutes) = 14.88' (minutes)
14.88' (minutes) divided by 60 = 0.248' (degrees)
51° (degrees) + 0.248° (degrees) = 51.248° (degrees)
Entry:
1. Click in the input field.
2. Enter the coordinates according to the example.
Long. [ddd.dd][+ = East, − = West]
■
Options:
The parameter is used to set the geographic longitude for the location of the device (180°
East to 180° West)
This setting is important for the astro function. The entry is made in decimal degrees. The
minutes and seconds must be converted for the entry.
One degree corresponds to 60 minutes.
For example:
7°36' 13' East (7 degrees, 34 minutes 13 seconds East) = +7.60 decimal degrees
Example of calculation:
13' (seconds) divided by 60 = 0.22' (minutes)
36' (minutes) + 0.22' (minutes) = 36.22' (minutes)
36.22' (minutes) divided by 60 = 0.603' (degrees)
7° (degrees) + 0.603° (degrees) = 7.603° (degrees)
Entry:
1. Click in the input field.
2. Enter the coordinates according to the example.
