When autosizing the low speed air flow rate and low speed capacity a ratio of 1/3 is used. This is hard coded into the program and cannot be changed. This is not mentioned in the Input Output Reference document but I did find it in the sizing section of the Engineering Reference.
10.7.13 DX Coil Sizing
10.7.13.13 Rated Air Volume Flow Rate, low speed
The rated air volume flow rate, low speed, is set equal to 1/3 times the full rated air volume flow rate.
10.7.13.14 Rated Total Cooling Capacity, Low Speed
The rated total cooling capacity, low speed, is set equal to 1/3 times the full rated total cooling capacity.
