Astronomical coordinates setting menu
The setting of the geographical coordinates of the installation place allows DWA to calculate, for each day of the year, sunrise and sunset
times.
To simplify the procedure, in the DWA are stored the coordinates of the locations listed below; if your location is among them you can select
it from the menu , otherwise it’s necessary to enter the coordinates of latitude and longitude (menu ).
Note: the display on point shows “---------” if the coordinates have been entered.
Location stored in DWA: Major cities of France, Germany, Italy, Russia, Spain, United Kingdom
and some other major cities in the rest of the world
The correction of sunrise and sunset times is useful for applications that require the turning on of lights in particular localities. It’s possible, in
fact, that the presence of disturbing elements, such as the mountains, can influence actual times of sunrise and sunset, making it necessary
to advance or delay of a few minutes the calculated times.
The twilight is the time interval before sunrise, or after sunset, characterized by the permanence of the light due to the spread by the atmo-
sphere of the Sun light. During these time intervals it’s possible to distinguish clearly objects and conduct outdoor activities without using
additional lighting. Therefore, in some applications it is more interesting to take as times of switching on and off the twilight (civil) in place
of sunrise and sunset. With DWA it’s possible to choose to turn on/off the loads depending on the times of sunrise and sunset or the civil
twilight. The calculated time correction also applies to the times of twilight. To view the calculated switching on time (sunset) and switching
off time (sunrise), from the main page press the key (see page 8).
