• Protection Functions: The integrated protection functions (e.g., overload, phase protection) are designed to safeguard the system. If these functions activate frequently, investigate the underlying cause rather than bypassing them.

6. Troubleshooting

If you encounter issues with your ECB-2030W control panel, refer to the following basic troubleshooting steps:

• No Power: Check the main power supply to the unit and ensure all circuit breakers are in the 'ON' position. Verify all power connections are secure.
• Incorrect Temperature Reading: Inspect the temperature sensors. Ensure they are correctly installed, clean, and not damaged. Verify sensor wiring.
• System Not Cooling/Defrosting: Check the operational mode. Verify that the compressor, fan, and defrost heaters are receiving power and are functioning correctly. Look for any active protection alarms on the display.
• Communication Issues (RS485/App): Ensure the RS485 wiring is correct and secure. Verify network connectivity for the remote monitoring device (PC/mobile).
• Error Codes: If an error code is displayed, consult the full product manual for a detailed explanation of the code and recommended corrective actions.

For complex issues or if troubleshooting steps do not resolve the problem, contact qualified technical support.
