Yes, that warning is saying that the curves do not cover a broad enough range of temperatures for the actual operating conditions. This is a common problem with energy modeling because the annual operating ranges are often wider than that available in catalog data for design. Often need to just ignore this warning because the data are not available. But here with ice storage charging you are intentionally running the chiller much colder than usual for chilled water, so I think it would be better to develop or find curves known to be appropriate ice production.
