3. Automatic Reclosing Mode:
The Smart RCBO features an automatic reclosing function to restore power after a trip, provided the fault is temporary.

Imagen: Flowchart illustrating the automatic reclosing mode. It details the sequence of attempts (up to 3) with 30-second intervals after a trip, and the conditions for reclosing or remaining off, including leakage, overcurrent, overpower, overvoltage, y subvoltage.
- After a trip due to leakage, overcurrent, overpower, overvoltage, o subvoltage, the device will attempt to reclose up to three times.
- Each reclosing attempt is spaced by 30 seconds.
- If the fault persists after three attempts, the circuit breaker will remain open for 15 minutes before attempting to reclose again. If the fault is still present, the system will reset to OFF.
- Nota de seguridad: The device will NOT reclose automatically in case of a short-circuit or excessive temperature to ensure safety.
- You can manually rearm the breaker via the Tuya Smart app if automatic reclosing fails or is disabled.

Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| El dispositivo no se enciende. | No hay fuente de alimentación; cableado incorrecto. | Verifique el disyuntor principal; verifique las conexiones del cableado. |
| La conexión Wi-Fi falla o es inestable. | Incorrect Wi-Fi password; 5GHz network used; device too far from router; router issues. | Ensure correct 2.4GHz Wi-Fi password; move device closer to router; restart router; re-pair device. |
| Automatic reclosing does not work. | Feature disabled in app; persistent fault (short-circuit, high temperature); incorrect settings. | Enable "Automatic Closing Switch" in the app's Advanced Function settings. Check for persistent faults and resolve them. Manually rearm via app if necessary. |
| OLED display is blank or shows incorrect data. | Sin energía; mal funcionamiento del dispositivo. | Check power supply. If power is present and display is still blank, contact support. |
| App instructions do not match current app interface. | App updates have changed the interface. | Refer to the latest in-app help or online resources for updated instructions. The core functionality remains, but menu paths may differ. For example, auto-reclosing settings might be under "Param set" instead of "Advanced functions". |
