The following figure in I/O Reference suggests that we should select one Air Distribution Unit per zone, but can we select multiple Air Distribution Units per zone? In other words, can we select multiple Airloops per zone?

I want model HVAC system with PAU(Primary Air Handling Unit) +AHU. To do this, I think I need to add 2 Air Distribution Units to each zone. Below is my image of how I would model the HVAC system with PAU+AHU. The actual number of zones is more than 100 and there are many PAUs and AHUs, but this illustration is simplified.

ZoneHVAC:EquipmentConnections has Zone Air Inlet Node or NodeList Name and Zone Air Exhaust Node or NodeList Name fields, so I guess I can input multiple Nodes to these fields by using NodeList, but I'm not so sure.

If there is an ExampleFile with such a system, it would be even more helpful.
