That warning means the DX cooling coil has an air volume flow rate about 2 times higher than expected.

The volume to capacity ratio for DX coils is DX coil volume air flow/DX coil cooling capacity.

The expected range is around 0.00004 - 0.00006 m3/s/W.0.00006.

The coil air flow is too high or the coil capacity is too low.
