Question / Problem

How do I complete the initial time, date, location and Daylight Saving Time setup on an EI-501 Series timer?

Common Application / Operating Conditions

• The timer is installed and connected to power.
• The display is active.
• You know the current time, date, time zone and approximate Astronomic Zone.

Step-by-Step Resolution

1. Start the Initial Setup

   Open the timer door and locate the small, recessed Reset button near the bottom center of the control panel, between the Mode/Del and Home buttons. Use a toothpick, paper clip or pencil to press the Reset button. The display should begin flashing 12:00 AM. If the time is not flashing, press and hold Set until it flashes.

2. Set the Current Time

   Press + or - to set the time. Continue through the clock to change between AM and PM, then press Set.

3. Set the Date

   Use + or - to select the year and press Set. Repeat this process for the month and day.

4. Set the Time Zone

   Use + or - to select your time zone, then press Set.

5. Select the Astronomic Zone

   Use + or - to select CENTER, SOUTH, HAWAII, ALASKA or NORTH. Use the zone map in the EI-501 Series user guide to identify the correct zone. Press Set.

6. Adjust Daylight Saving Time Setting

   Use + or - to turn DST on or off based on whether your location observes Daylight Saving Time.

7. Finish Setup

   Press Set. The timer returns to the Home screen and saves the settings.

Tips / Additional Notes

• Press and hold + or - to scroll through time values faster.
• The date and Astronomic Zone determine the calculated dawn and dusk times.
• For later changes, press and hold Set from the Home screen instead of pressing Reset.
