Key Features and Specifications
The Intermatic DT620 timer boasts several key features that make it a standout choice for automated timing needs. It operates on an input of 102-132 VAC at 60 Hz, consuming a maximum of 2.5W. The timer provides a 15A output, supporting up to 1800W for resistive loads and 12A for inductive loads.
Additionally, it handles 8.3A for tungsten loads (up to 1000W) and is suitable for 1/2 HP motors. The DT620 includes 7-day programmable settings, allowing users to customize schedules for each day of the week. It also features an astronomical clock and Daylight Saving Time (DST) adjustment for added convenience.
The timer offers multiple modes⁚ AUTO, MANUAL, and RANDOM. MANUAL mode allows direct control of plugged-in devices, while AUTO follows the programmed settings. The RANDOM mode varies the timer’s settings by approximately 5-minute increments. An output status indicator shows whether the connected device is currently ON or OFF.
Understanding the Timer’s Modes⁚ AUTO, MANUAL, and RANDOM
The Intermatic DT620 timer offers three distinct operational modes⁚ AUTO, MANUAL, and RANDOM, each catering to different user needs. The AUTO mode is designed to execute pre-programmed ON/OFF schedules precisely as set by the user. This mode is ideal for consistent, automated control of lights or appliances according to a defined routine.
In MANUAL mode, users can override the programmed settings and directly control the connected devices. This allows for immediate activation or deactivation of lights or appliances without altering the scheduled settings.
The RANDOM mode introduces variability to the programmed schedule. In this mode, the timer randomly adjusts the ON/OFF times by approximately 5-minute intervals. This feature is useful for creating a more natural, less predictable pattern, which can be beneficial for security purposes by giving the impression of occupancy even when the space is vacant. Understanding these modes ensures optimal use of the DT620’s capabilities.
Programming the Intermatic DT620⁚ A Step-by-Step Guide
To effectively program your Intermatic DT620, begin by ensuring the timer is in a normal operating mode. Navigate through the modes (MANual, AUTO, RANDom) using the MODE button. Next, initiate the programming sequence by pressing the PROG button. The screen will display “01,” indicating the first available event setting.
Use the appropriate buttons to set the desired ON time for the first event. After setting the ON time, confirm by pressing OK, then proceed to set the OFF time for the same event. Repeat this process for each event you wish to program, up to the timer’s capacity.
For each event, you can also select specific days of the week by using the SKIP button to customize the schedule. Once all events are programmed, return to the AUTO mode to enable the scheduled operations. This step-by-step approach ensures accurate and efficient programming of your Intermatic DT620 timer.
Setting the Clock and Date
To accurately set the clock and date on your Intermatic DT620 timer, first ensure the device is in CLOCK mode. If it’s not already displayed, press the MODE button until “CLOCK” appears on the screen. This ensures you’re in the correct setting for adjustments.
Next, use the designated buttons to adjust the current year. Once the year is correctly set, press the OK button to move to the month setting. Adjust the month accordingly, and again, press OK to proceed. Repeat this process for setting the day.
Finally, set the current time, paying attention to AM/PM if applicable. After setting both the hour and minutes, press OK to save the changes. Your Intermatic DT620 timer is now accurately set with the current date and time, ensuring proper scheduling and operation of your programmed events. Verifying these settings regularly ensures continued accuracy.
Creating ON/OFF Schedules
Creating ON/OFF schedules with your Intermatic DT620 timer enables automated control of connected devices. Start by pressing the PROG button from either MAN, AUTO, or RAND mode to enter programming mode. The display will show a flashing “01,” indicating the first event slot.
Use the arrow buttons to select the desired ON or OFF setting for the event. Press OK to confirm, and then set the desired time for the event to occur. You can select specific days or groups of days for the schedule. For example, you can set the timer to turn on lights every weekday at 6 PM and turn them off at 6 AM.
Once the schedule details are entered, press OK to save the settings. Repeat these steps for each additional event you wish to program. The DT620 allows for multiple ON/OFF events, providing extensive control over your devices. Confirm all scheduled times are correctly set to ensure proper functionality.
Daylight Saving Time (DST) Adjustment
Adjusting for Daylight Saving Time (DST) on your Intermatic DT620 is crucial for maintaining accurate schedules throughout the year. To enable or disable the DST function, navigate to the clock settings. After choosing AUTO or MANual, press the OK button. The timer’s starting date for DST will show in the display.
Typically, the DT620 has an automatic DST adjustment feature. You can usually find the DST setting within the clock or date setup menu. Follow the prompts to either turn DST on or off, depending on the current time of year.
When DST is enabled, the timer will automatically advance the clock by one hour in the spring and revert it back in the fall. This ensures your programmed schedules align with the actual time, preventing any disruptions in your automated tasks. Verify the DST setting biannually to guarantee its proper function.
Troubleshooting Common Issues
Encountering issues with your Intermatic DT620 timer can be frustrating, but many problems have simple solutions. Start by ensuring the timer is receiving power and the outlet is functional.
If the timer isn’t working as expected, verify that it is in the correct mode (AUTO, MANUAL, or RANDOM) for your desired operation. Double-check all programmed settings to confirm the on/off times are accurately set.
For display issues, a reset might be necessary. Press and hold the ON/OFF button, then press and release the reset button with a blunt object. If the timer still isn’t functioning, check the battery and replace it if needed. Always ensure the load connected to the timer does not exceed its maximum rating to prevent damage. Refer to the manual for detailed troubleshooting steps.
Timer Not Turning On/Off as Scheduled
If your Intermatic DT620 timer isn’t switching devices on or off as programmed, several factors could be at play. First, ensure the timer is set to AUTO mode; otherwise, it will not follow the programmed schedule. Verify the accuracy of your programmed on/off times, paying close attention to AM/PM settings.
Check if Daylight Saving Time (DST) adjustments are correctly configured. An incorrect DST setting can cause the timer to be off by an hour. Confirm that no conflicting manual overrides are active.
Another potential issue is the load exceeding the timer’s capacity, leading to overload protection activation. Ensure the connected device’s power requirements are within the timer’s specifications. If problems persist, try resetting the timer.
Display Problems and Error Messages
Encountering display issues or error messages on your Intermatic DT620 can be frustrating, but often resolvable. If the display is blank, first ensure the timer is receiving power from a properly grounded outlet. If it is, the internal battery might be depleted, requiring replacement.
Faint or flickering displays can also indicate low battery power. Error messages typically signal specific issues. Consult the manual for a detailed explanation of each error code and recommended solutions.
Sometimes, a simple reset can clear up minor glitches. Press and hold the ON/OFF button, then press and release the reset button using a blunt object. If the display remains problematic after these steps, consider contacting Intermatic support for further assistance.
Battery Installation and Replacement
The Intermatic DT620 relies on a battery to maintain its settings during power outages. When the display is dim or settings are lost, it’s time for a replacement. To replace the battery, first, unplug the timer from the power outlet for safety.
Locate the battery compartment, usually on the side or back of the unit, and open it using a small screwdriver if necessary. Remove the old battery, noting its orientation (+ and -). Install a new battery of the correct type, ensuring the correct polarity.
Carefully close the battery compartment. Plug the timer back into the outlet and allow it to charge. Reset the time and date as needed. Regular battery replacement ensures consistent performance.
