The Intermatic DT620 offers three programming modes: MAN (Manual), AUTO, and RAND (Random). In MAN mode, you can manually override the timer for immediate control. AUTO mode follows the programmed schedule, ideal for consistent automation. RAND mode introduces randomness to your schedule, varying on/off times slightly to enhance security. Each mode provides flexibility, catering to different needs. Use MAN for temporary adjustments, AUTO for reliability, and RAND for added security. Understanding these modes ensures efficient use of the timer’s capabilities.
3.2 Setting Dusk and Dawn Timings
The Intermatic DT620 calculates dusk and dawn times using its astronomical clock, adjusting based on your location and date. For precise control, you can manually set minutes before sunset and after sunrise. Ensure your location and time zone are correctly programmed. Adjustments are made in the CLOCK mode, allowing fine-tuning to match your specific needs. Refer to the manual for step-by-step guidance on initializing these settings for accurate automation of your lighting schedule.
3.3 Creating Custom On/Off Events
The Intermatic DT620 allows you to create up to 28 custom on/off events per week. To program, enter the desired mode (MAN, AUTO, or RAND) and press PROG. Select the event number, set the time, and choose ON or OFF. Repeat for additional events. Use the +/- buttons to adjust timings. Save your settings to ensure they take effect. This feature offers flexibility for tailored lighting schedules, whether for security, energy efficiency, or convenience. Refer to the manual for detailed step-by-step instructions to maximize customization.
