[EnergyPlus_Support] Re: Regarding the problem of Cooling Coil sizing





I get this warning even if both the "gross rated total cooling capacity" and the "rated air flow rate" are autosized, e.g.:

    Air Loop Blocco principale:Area prep AHU/1 Unitary Cooling Coil DX Cooling Coil,  !- Name
    2,                       !- Availability Schedule Name
