This is likely caused by a discrepancy in the Coil:Cooling:Water object design temperature/humidity ratio, plant water temperature (Sizing:Plant), Sizing:System supply air temperature (assuming an air loop coil) or Sizing:Zone supply air temperature (assuming a zone coil) inputs. Feel free to ask more questions on this subject.
