[EnergyPlus_Support] Can Eplus process expression as input?

Hi all,

although in Input output reference I found that E+ can take an expressions instead of fixed values, I am not sure my variable fan model does that (what variable should I measure, since fan power consumption is 0 in my case). This is with numbers - I was trying to optimize it using genopt.

Fan:VariableVolume,
    DUPLA FASADA1 Supply Fan,!- Name
    HVACTemplate-Always 1 DSF,  !- Availability Schedule Name
    0.7,                     !- Fan Efficiency
    100,                     !- Pressure Rise {Pa}
    =15*(0-1)*40*8/3600,     !- Maximum Flow Rate {m3/s}
    Fraction,                !- Fan Power Minimum Flow Rate Input Method

Thanks in advance
