3.3 Initial Power-up and Settings
Upon initial power-up, the device may require setting the current time and date. Refer to the display and use the navigation buttons (typically indicated by arrows and an 'Enter' or 'Return' symbol) to adjust these settings. The internal CR2032 battery ensures that settings are retained during power outages.
4. Operating Instructions
4.1 Programming ON/OFF Times
The Talento 371 Easy Plus allows for up to 20 ON/OFF program steps. To set a program:
- Enter programming mode (refer to the device's display for specific button presses, usually a 'P' or 'Menu' button).
- Select a program number (1-20).
- Set the desired ON time (hour and minute).
- Set the desired OFF time (hour and minute).
- Select the days of the week for which this program should be active (e.g., Monday-Friday, daily, or specific days).
- Confirm and save the program. Repeat for additional program steps.
4.2 Weekly and Holiday Programs
The device supports weekly programming, allowing different schedules for each day. Additionally, a holiday program feature enables you to define specific periods where the regular schedule is temporarily suspended, useful for extended absences.

4.3 Manual Override
A manual override function is available to temporarily switch the output ON or OFF, independent of the programmed schedule. This is typically accessed via a dedicated button or a combination of buttons. The device will return to its programmed schedule at the next scheduled switching event.
5. Maintenance
5.1 Battery Replacement
The device uses a CR2032 battery to maintain time and program settings during power outages. If the display becomes dim or settings are lost frequently, the battery may need replacement. To replace the battery:
- Disconnect all power to the device.
- Carefully open the battery compartment (refer to the device casing for location, usually on the side or back).
- Remove the old CR2032 battery.
- Insert a new CR2032 battery, ensuring correct polarity.
- Close the battery compartment and restore power.
5.2 Cleaning
Clean the exterior of the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.
6. Troubleshooting
- Device not powering on: Check the main power supply to the device. Ensure all wiring connections (L and N) are secure and correct.
- Programs not executing: Verify that the current time and date are set correctly. Check that the program steps are enabled for the desired days and times. Ensure the manual override is not active.
- Incorrect time display: The internal battery (CR2032) might be low or depleted. Replace the battery as described in Section 5.1.
- Display is dim or blank: This often indicates a low or dead CR2032 battery. Replace the battery.
If problems persist after following these steps, contact Grässlin customer support or a qualified electrician.
