AstroGPS

AstroGPS calculates sunrise and sunset using geographic coordinates.

This function is used to naturally simulate the photoperiod of a place, even when the control unit is installed in a closed room.

MENU -> Usa il programma -> Prg: AstroGPS -> ENTER

Screens displayed:

Control unit location

Control location indicates where the device actually is.

The menu asks:

• Lat:
• Long:
• UTC:

This data allows the control unit to correctly place the day in the actual place of installation.

Latitude and longitude

Commands:

• LEFT and RIGHT move the cursor;
• UP increases the selected value;
• DOWN decreases the selected value;
• on the sign, UP or DOWN change North/South or East/West;
• ENTER confirms.

On the display, West longitude can be indicated with the letter O.

UTC

UTC: sets the real location's time difference from UTC.

Commands:

• LEFT increases by 1 hour;
• RIGHT decreases by 1 hour;
• UP increases by 15 minutes;
• DOWN decreases by 15 minutes;
• ENTER confirms.

Simulated location

Simul. location is the place whose photoperiod you want to reproduce.

The menu asks:

• Lat:
• Long:

Example: the control unit can be installed in Emilia, but simulate a place with a different season to gradually shift the light-dark cycle.

Twilight

The Twilight: screen allows you to enable or disable twilight management.

Values:

• Enabled
• Disabled

With dusk enabled, light begins and ends more gradually around sunrise and sunset events.

With dusk disabled, SOL-7000 uses sunrise and sunset as primary references.

Recommended checks

After configuring AstroGPS, check:

• date and time of the control unit;
• coordinates of the real place;
• coordinates of the simulated place;
• UTC value;
• status of Twilight:;
• consistency of times displayed on the main page.
