- Overvoltage Protection: 220-265V adjustable
- Undervoltage Protection: 76-240V adjustable
- Temperature Protection: 40-150°C adjustable
- Power-on Response: Configure the device's state after a power outage and subsequent restoration. It can be set to restore its previous state, or to be always ON or always OFF.
6. Maintenance
The EAWCBT-P is designed for minimal maintenance. Periodically inspect the wiring connections for tightness and ensure the device is free from dust and debris. Do not attempt to open or repair the device yourself; contact qualified service personnel.
7. Troubleshooting
- Device not powering on: Check main power supply and wiring connections. Ensure Live and Neutral are correctly connected.
- No Wi-Fi connection: Verify your Wi-Fi network is 2.4GHz. Ensure the device is within range of your router.
- Device trips frequently: Check the current, voltage, power, and temperature thresholds set in the app. Reduce the load or adjust thresholds if necessary, ensuring they are within safe operating limits.
