Operating Instructions

The DAT100 timer offers flexible programming for various applications.

1. Understanding the Display: The large LCD screen shows the current time, day, and active program status. A low battery indicator may also appear here.
2. Programming On/Off Cycles (Up to 28 Settings):
   • Press the PROG button to enter programming mode.
   • The display will show "PROG 1 ON". Use the rotary dial or buttons to set the desired ON time for the first program.
   • Press OK to confirm. Then set the days of the week for this program (e.g., Mon-Fri, daily, specific days).
   • Repeat for "PROG 1 OFF" time.
   • Continue this process for up to 28 distinct ON/OFF programs.
   • Press MODE to exit programming mode.
3. Dusk-to-Dawn Feature: This timer can automatically adjust its ON/OFF times based on local sunrise and sunset. Refer to the specific instructions for enabling and configuring this feature, which typically involves selecting a "Dusk-to-Dawn" or "Astronomical" mode.
4. Manual Override: The ON/OFF button allows for manual control, overriding the current program. Pressing it will toggle the connected appliance between ON and OFF states. The timer will resume its programmed schedule at the next scheduled event.
5. Connecting Appliances: Plug your appliance(s) into the two grounded receptacles on the timer. Ensure the total load does not exceed the timer's maximum rating (15A/1800W).

Maintenance

• Battery Replacement: If the low battery indicator appears on the display, replace the internal battery promptly to ensure program retention during power outages. Refer to the timer's casing for battery type and replacement instructions. Typically, this involves opening a small compartment and inserting a new battery of the specified type.
• Cleaning Instructions: Disconnect the timer from the power outlet before cleaning. Wipe the exterior with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as these can damage the unit.

Troubleshooting

• Display is Blank:
  • Ensure the timer is securely plugged into a live outlet.
  • Check if the internal battery needs replacement.
• Programs Not Running:
  • Verify that the current time and day are set correctly.
  • Confirm that the programs are enabled and set for the correct days.
  • Check if the manual override is active.
• Appliance Not Turning On/Off:
  • Ensure the appliance is properly plugged into the timer and is functional.
  • Check the timer's current status (ON/OFF) and programmed schedule.
• Resetting the Timer: If the timer behaves erratically, a full reset may be necessary. Locate the small reset button (often recessed) and press it with a pointed object (e.g., a paperclip). This will clear all settings, requiring you to reprogram the unit.
