To combine Astronomic and fixed events, only program one event in each ON/OFF event pair for both Astro and Fixed events. For
example, a combination Astro and fixed event schedule could be a Sunset ON and a Fixed event off for 10 P.M. It is recommended to
determine your facility schedules in advance and then program the time switch. If applicable, different combinations can be configured
for different loads.
Follow these guidelines to configure a combination Astro and Fixed Event schedule.
1. Program the Sunset ON or Sunup OFF events for the applicable loads as instructed in Setting Astro On/Off Events.
NOTE: After a Sunset or Sunup is configured, be sure to leave the other On or Off event blank.
2. Press MODE to scroll to SET FIXED ON/OFF.
3. Program the Fixed ON or Fixed OFF events for the applicable loads as instructed in Setting Fixed Timed Events.
NOTE: After a Fixed ON or OFF is configured, be sure to leave the other ON or OFF event blank.
4. When all the schedules are complete, press MODE to exit the fixed event screen.
Daily Operation

10. Press MODE to place the time switch in AUTO (Mode). This enables the time switch to automatically initiate configured
scheduled events.
NOTE: In AUTO Mode, the time switch follows the user-configured events, and the loads turn ON and OFF at the configured
time(s). In MANUAL mode, the time switch does not follow user-configured events and only activates loads when an ON/
OFF button is pressed. Press MODE again to return the controller to MANUAL mode.
NOTE: In Auto Mode, press an ON/OFF button temporarily overrides the current state of the load. The time switch returns to the
normal schedule at the next configured event.
