Re: [EnergyPlus_Support] about the node error

["Michael J. Witte" <mjwitte@xxxxxxxx>]

The outside air inlet must be listed in an OUTSIDE AIR INLET NODE LIST object.  
We will change this error message to read:  

". . . Inlet node did not find an appropriate matching "outlet" node.  If this 
is an outside air inlet node, it must be listed in an OUTSIDE AIR INLET NODE 
LIST object."
