The E-20 error code for the Haier MRV 5 Series VRF indoor unit indicates a "4-way valve reversing failure." This occurs when the 4-way valve, which switches between heating and cooling modes, encounters an issue.

The outdoor unit displays the error code 26-2 before stopping automatically because it detects that the number of connected indoor units is more than the set number for 300 seconds. This suggests a mismatch in the system configuration, leading to an automatic stop for protection.

The E-20 error code in the Haier MRV 5 Series indicates a compressor start failure. To resolve this issue, follow these steps:

1. Check the resistance between U, V, and W terminals of the compressor to ensure it is within standard values (e.g., 0.16Ω to 0.31Ω at 20°C).
2. Measure the resistance between each terminal (U, V, W) and ground. If any are not "OL" (open line), the compressor may be faulty.
3. If resistance values are incorrect, replace the compressor.
4. If resistance values are correct, replace the power module.
5. If the issue persists after replacing the power module, replace the compressor.
