EnergyPlus: enforcing user defined fan speed for air handler at each timestep

Hello all:

Does anyone know of a way to either input a schedule for fan speed or a way to create a custom fan object that allows a user to specify fan speed at each time-step?

For my current study it would be nice to look closely at behavior of VFD control sequences. I have looked at the idf fields for Fan:VariableVolume, Fan:ComponentModel, Fan:ConstantVolume, and Fan:OnOff, and it does not appear that this is possible.

I believe one way this could work is if it were possible to enter a schedule value for certain relevant fan only it does not appear that this is yet possible as these fields expect a number only. Does anyone have an idea for a work around or another possible solution? Your help would be much appreciated.

Best regards, Tyler Noble
