Question / Problem

How do I set up, change, and review holiday schedules on my ET70000 Series timer?

Common Application / Operating Conditions

Holiday programming allows you to override the regular ON/OFF schedule on specific dates. When a holiday is programmed, the normal schedule is omitted for that day. You can also add specific ON and OFF events that apply only during the designated holiday period.

Programming Holidays (Factory Reset)

Note: This procedure clears all existing events. After you create your holiday events, you must reprogram your regular ON/OFF schedules.

  1. Enable all circuits that you plan to program.
  2. Move the RUN/SET switch to the SET position.
  3. Press and hold the CLEAR button.
  4. While holding CLEAR, press and release the RESET button (located in the upper left corner of the programming panel). It is recommended to use a paperclip or similar tool for this step.
  5. When the display reads RESET, release the CLEAR button.

Note: If your timer has an older firmware version, you may need to enter the day and time before entering the date.

  1. Enter the current date in MM-DD-YY format.
  2. Press OK to confirm the date.
  3. Enter the current time in HH-MM format, then select AM or PM as appropriate.
  4. Press OK to confirm the time.
  5. Select the correct time zone.
  6. Press OK to confirm the time zone.
  7. Confirm that the sunrise time is correct. If it is not, press CLEAR, enter the correct time in HH-MM format, and press OK.
  8. Confirm that the sunset time is correct. If it is not, press CLEAR, enter the correct time in HH-MM format, and press OK.
  9. Enter the holiday reference number (01 to 99).
  10. Press OK to confirm the reference number.
  11. Enter the start date for the holiday in MM-DD format.
  12. Press OK to confirm the start date.
  13. If the holiday spans multiple days, enter the end date in MM-DD format. For a single day holiday, use the same end date as the start date.
  14. Press OK to confirm the end date.
  15. Repeat steps 14 through 19 for each holiday that you want to program.
  16. Move the RUN/SET switch to the RUN position to save the setup.
  17. Move the RUN/SET switch to the SET position.
  18. Press the PROG button to begin programming holiday events.
  19. Press the HLDY button to access holiday settings.
  20. Enter the holiday number you want to configure.
  21. Press OK to confirm your selection.
  22. Enter the holiday ON time in HH-MM format and select AM or PM.
  23. Press OK to confirm the ON time.
  24. Enter the holiday OFF time in HH-MM format and select AM or PM.
  25. Press OK to confirm the OFF time.
  26. Repeat steps 23 through 28 for each holiday as needed.
  27. Move the RUN/SET switch to the RUN position when programming is complete.

  10. Move the RUN/SET switch to the RUN position when all changes are complete.

Review Holiday Switching Times

Tips / Additional Notes

  • Each holiday must use a unique reference number between 01 and 99.
  • Holiday programs temporarily replace normal circuit schedules on the programmed dates.
  • Always ensure the RUN/SET switch is in the RUN position after completing setup, changes, or programming.
  • On some older firmware versions, you may need to enter the day and time before entering the date when programming the clock.
