4. Installation
4.1 Mounting
The Dinuy IH AST MC0 is designed for DIN rail mounting (EN 60715). Ensure sufficient space in the electrical panel for proper ventilation and access to terminals.
- Ensure the main power supply to the electrical panel is disconnected.
- Hook the top edge of the device onto the DIN rail.
- Press the device downwards until it clicks securely onto the rail.
4.2 Wiring Diagram
Refer to the terminal markings on the device for correct wiring. The device requires a 230V~ power supply and provides a single switching contact.
| Terminal | Description |
|---|---|
| L | Phase (230V~) input |
| N | Neutral input |
| 1 | Common contact for switching output |
| 2 | Normally Closed (NC) contact |
| 3 | Normally Open (NO) contact |
Connect the load to terminals 1 and 3 for normally open operation (load turns ON when the timer activates) or 1 and 2 for normally closed operation (load turns OFF when the timer activates).
Warning: Incorrect wiring can damage the device or cause electrical hazards. Consult a professional if unsure.
5. Initial Setup
After successful installation and power-up, the device will require initial configuration.
5.1 Setting Date and Time
- Press the 'M' (Menu) button to enter the main menu.
- Navigate using the arrow buttons to find the 'Time/Date' setting.
- Press 'OK' to select.
- Adjust the year, month, day, hour, and minute using the arrow buttons and confirm each setting with 'OK'.
5.2 Setting Location for Astronomical Function
Accurate location data is crucial for the astronomical function to calculate sunrise and sunset times correctly.
- From the main menu, navigate to 'Location' or 'Astro Settings'.
- Select the method for entering location:
- Postal Code: Enter your local postal code. The device will automatically determine the coordinates.
- UTM Coordinates: Manually enter the Universal Transverse Mercator coordinates.
- GPS (via NFC): Use the smartphone app to transfer GPS coordinates directly (see Section 6).
- Confirm the selected location.
6. NFC Programming
The Dinuy IH AST MC0 can be easily programmed using a smartphone with NFC capabilities. This method offers a user-friendly interface for complex settings.
- Download App: Download the free Dinuy app from the Google Play Store (for Android devices).
- Enable NFC: Ensure NFC is enabled on your smartphone.
- Create Program: Open the app and create your desired switching programs, including astronomical settings, night ON/OFF, and any special functions. You can also input location via GPS using the app.
- Transfer Data: Hold your smartphone close to the NFC symbol on the timer (visible on the upper right of the display area). The app will indicate successful data transfer.
- Verify: Check the timer's display to confirm the new settings have been applied correctly.
Note: Programming via NFC can be done even when the device is not powered, as long as the internal battery has charge.
7. Operating Instructions
7.1 Manual Override
The 'OK/ON/OFF' button allows for temporary manual override of the programmed state.
- Pressing 'OK/ON/OFF' once will toggle the output state (ON to OFF, or OFF to ON) until the next programmed switching event.
- The display will indicate the manual override status.
7.2 Astronomical Function
Once the location is set, the timer automatically calculates sunrise and sunset times daily. You can configure programs to activate or deactivate loads relative to these times (e.g., ON at sunset, OFF at sunrise, or ON 30 minutes before sunset).
7.3 Night ON/OFF
The device supports up to 4 memory locations, allowing for specific ON/OFF times during the night, in addition to the astronomical function. This is useful for applications requiring lights to be off during specific late-night hours.
7.4 Security PIN
To prevent unauthorized access or manipulation, a security PIN can be set through the menu or NFC app. Once activated, the PIN must be entered to access programming or change settings.
7.5 Automatic Summer/Winter Time Change
The device automatically adjusts for daylight saving time changes (summer/winter time) based on the configured region, ensuring accurate scheduling without manual intervention.
8. Maintenance
8.1 Cleaning
Clean the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or liquids, as these can damage the casing or internal components.
8.2 Battery Replacement
The device contains an interchangeable CR2032 lithium battery for power reserve. This battery typically lasts up to 10 years. If the display shows a low battery indicator or settings are lost during power outages, the battery may need replacement.
- Disconnect the main power supply to the device.
- Locate the battery compartment (usually on the front or side, refer to device markings).
- Carefully remove the old CR2032 battery.
- Insert a new CR2032 battery with the correct polarity.
- Dispose of the old battery according to local regulations.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power supply; Faulty wiring; Dead internal battery (if no mains power) | Check mains power connection; Verify wiring; Replace CR2032 battery. |
| Load does not switch ON/OFF | Incorrect program; Incorrect wiring of load; Load fault; Manual override active | Review program settings; Check load wiring (terminals 1, 2, 3); Test the load independently; Deactivate manual override. |
| Astronomical times are inaccurate | Incorrect location set; Incorrect date/time | Verify and correct location settings (Postal Code/UTM/GPS); Ensure date and time are accurate. |
| NFC programming fails | NFC not enabled on phone; Phone not positioned correctly; App issue | Ensure NFC is active; Hold phone directly over the NFC symbol; Restart app/phone. |
| Settings are lost after power outage | Dead or low internal CR2032 battery | Replace the CR2032 battery. |
