Re: [EnergyPlus_Support] Invalid AirLoop component



There are no HVAC systems that use a Fan:OnOff on a branch, only 
Fan:ConstantVolume or Fan:VariableVolume. The only way to use a 
Fan:OnOff object is to use it with a unitary HVAC system where the fan 
is part of the AC unit. See AirLoopHVAC:Unitary:HeatCool or 
AirLoopHVAC:UnitaryHeatPump:AirToAir for examples. 
FurnaceWithDXSystem.idf and HeatPump.idf example files show how to 
connect these types of HVAC systems.
