What are the density value being used for supply air mass flow rate and outdoor air mass flow rate, for Controller:OutdoorAir object? Is the density standard ==1.204 kg/m3, or is a function of temperature? I output standard density volume flow rate and current density volume flow rate, and found they are different.
