RoomAir:Node:AirflowNetwork:HVACEquipment does not work with air terminal units

[mjwitte]

Issue overview

When RoomAir:Node:AirflowNetwork:HVACEquipment is used with an air terminal unit, such as AirTerminal:SingleDuct:ConstantVolume:NoReheat, the simulation fails with a fatal error.

   ** Severe  ** GetRoomAirflowNetworkData: The equipment listed in ZoneEquipList is not found in the lsit of RoomAir:Node:AirflowNetwork:HVACEquipment objects =
   **   ~~~   ** NORTH_ZONE PTAC ADU. Please check inputs of both objects.

The room air model is checking if every item on the ZoneHVAC:EquipmentList has a corresponding RoomAir:Node:AirflowNetwork:HVACEquipment object, but air terminal units do not appear directly on the equipment list, they are inside a ZoneHVAC:DistributionUnit object.

Prior to v9.3, AirTerminal:SingleDuct:Uncontrolled ran ok, because that type of terminal unit did go directly on the zone equipment list. But that object was transitioned to AirTerminal:SingleDuct:ConstantVolume:NoReheat which does live inside an air distribution unit, so now it's broken.

RoomAir:Node:AirflowNetwork:HVACEquipment in the IDD lists many other AirTerminal:* as options, but it appears that those never worked.

Details
