This message says that the Cooling Capacity Ratio Modifier Function of Temperature Curve does not output a 1.0 at the rating conditions of 19.44 C indoor wet-bulb temperature and 35 C outdoor dry-bulb temperature. The correction is to check this performance curve as to why the cooling capacity modifier is not 1.0 at these conditions. It may be that the curve is correct, but likely there is an issue since input data (capacity, airflow, etc.) is usually at the rating point. The curve output = 1.136, does the cooling capacity input data multiplied by 1.136 equal the rated capacity of the unit at these rating conditions?
