Is there a way to model a fan powered box with a Fan:VariableVolume
in EnergyPlus? The input/output guide for AirTerminal:SingleDuct:ParallelPIU:Reheat
shows it is currently only possible in EnergyPlus 9.0 to use Fan:ConstantVolume
or Fan:SystemModel
. FPBs commonly use VFDs such as the Price FDV5.
