Programming
Programming the Intermatic DT620 Series Digital Timer is a straightforward process that allows you to customize your lighting and appliance schedules with ease. The timer’s digital display and intuitive controls make it user-friendly, even for those unfamiliar with programmable timers. Here’s a step-by-step guide to programming your DT620⁚
- Set the Time and Date⁚ After plugging in the timer, press and hold the ON/OFF button, then press and hold the RESET button for five seconds to clear any existing settings. Press MODE to display CLOCK, then press OK. Adjust the hours, minutes, month, date, and year using the up and down arrows.
- Set Your Location⁚ Press MODE to cycle through the options until you reach LOC. Press OK to adjust the latitude and longitude settings. This information is used by the timer to calculate sunrise and sunset times for the astronomical clock feature.
- Program Events⁚ Press PROG to access the programming menu. The screen displays a flashing 01, indicating the first event. Use the up and down arrows to select the desired day of the week and the hour and minute for the ON and OFF events.
- Select Operational Mode⁚ Choose between MANual, AUTO, or RANDom mode. MANual allows for manual operation, AUTO uses the exact timer settings, and RANDom uses the timer settings varied by random 5-minute increments.
- Confirm Settings⁚ Once you’ve programmed all your events, review them thoroughly to ensure accuracy. You can adjust or delete events as needed.
By following these simple steps, you can easily program your DT620 to meet your specific time control needs.
Modes of Operation
The Intermatic DT620 Series Digital Timer offers three distinct modes of operation, allowing you to tailor its functionality to your specific needs. Each mode provides different levels of control and automation, enabling you to choose the best option for your situation.
- MANual Mode⁚ In this mode, the timer operates like a standard on/off switch. You can manually turn the plugged-in device on or off using the timer’s ON/OFF button. This mode bypasses the programmed schedule, providing immediate control over the connected appliance.
- AUTO Mode⁚ This mode utilizes the programmed schedule you’ve set up. The timer will automatically turn the connected device on and off according to the specified times and days of the week. This is ideal for maintaining consistent schedules for lights, appliances, or other devices.
- RANDom Mode⁚ This mode adds an element of randomness to the programmed schedule. While it still follows the basic on/off times you’ve set, it introduces variations of up to 30 minutes, giving the impression that someone is home even when you’re away. This can be useful for deterring potential intruders or creating a more natural lighting pattern.
By understanding the different modes of operation, you can leverage the DT620’s versatility to achieve your desired level of automation and control over your indoor environment.
