How to change Fan from VariableVolume to ConstantVolume?

Hi, I am trying to change my HVAC system (PAU with VRF) fan from Variable Volume to Constant Volume in exp.idf file but it did not work out well. What I did is copy all the obj from Fan:VariableVolume and pasted in Fan:ConstantVolume. From the Output:Variable, I generated hourly data of Air System Mixed Mass Flow Rate and the data are showing the system still operates as variable volume.

Does anyone experience the same thing as I did? Can anyone give me advice how to solve this problem? Thank you in advance.
