To resolve the E2 error on a Gree GMV-Pdm224W/NaB-M evaporator ducted system:

1. Understand the cause: E2 indicates indoor antifreezing protection. It occurs when the evaporator temperature (Tevaporator) stays below -2°C for 10 minutes.

2. Action taken by system: The indoor electronic expansion valve closes, and the system capacity is set to 0.

3. Steps to resolve:
- Check if the indoor unit is exposed to very low temperatures.
- Inspect the electronic expansion valve for proper operation.
- Ensure the temperature sensor on the evaporator is working correctly.
- Confirm proper airflow and that filters and coils are clean.
- Restore normal operating conditions and restart the system.

This should clear the E2 error if the issue is corrected.
