Setting Sunup and Sunset Offset Times from Astronomic Sunup and Sunset Times
Normally, the time switch's sunup and sunset times match the actual occurrence of sunup and sunset (astronomic sunup and sunset
times). In some cases it is desirable to change the time switch's sunrise and sunset times so the circuit turns on or off either before
or after an actual sunup or sunset. For example, a user can set the lights in a parking lot to turn on 30 minutes before the normal
sunset time by changing the time switch's sunset time to 30 minutes (a 30 minute offset) before the normal sunset time.
Follow this procedure to adjust sunup and sunset times or press MODE to skip this procedure.
Press MODE to advance to the Offset mode selection if this selection is not already active. The SET and SUNUP icons appear
1.
at the top of the display. The default sunup time is displayed.
2.
Press + or - to adjust the time for sunup and press ENTER/NEXT. OFFSET briefly appears on the display, and then the offset
time (in minutes) is displayed.
NOTE: Offsets can be set to a maximum of 2 hours (120 minutes) before or after a sunup or sunset time. A minus sign (-)
appears before the digit to indicate minutes before a sunup or sunset time.
3.
If needed, press + or - to adjust the offset time value and press ENTER/NEXT to save the value.
4.
The updated sunup time is displayed.
Press MODE to save settings. The time switch displays SET and SUNSET icons at the top of the display. The default sunset
5.
time is displayed.
6.
Press MODE to save.
