Re: [EnergyPlus_Support] clarification

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

The restriction is probably better stated "Only one air loop terminal unit is 
allowed per zone."  Air terminal units are objects such as SINGLE 
DUCT:VAV:REHEAT and DIRECT AIR.  Some air terminal units connect directly to 
the zone splitter or supply plenum outlet, but some require an extra object 
called AIR DISTRIBUTION UNIT to complete the connection.  All of these types of 
objects apply to AIR PRIMARY LOOPs serving a zone.
