I ran your V9.6 file in the lastest EnergyPlus code and found a bug in the program. If there are multiple AirLoopHVAC:DedicatedOutdoorAirSystem objects then only the first objects find the correct outdoor air conditions used for sizing. I posted a new issue at https://github.com/NREL/EnergyPlus/issues/9325. This model uses the SizingPeriod:DesignDay conditions to find the outdoor weather.

In the fan model the Electric Power Minimum Flow Rate Fraction = 0.2. At flow fractions below 0.2 the fan power will remain constant. At 0 flow the power will go to 0.
