I was trying to model an air loop in OpenStudio which contains an outdoor air system and a Unitary system. When I try to enable economizer control in the outdoor air system, I am supposed to add a mixed air setpoint manager at the mixed air node as shown in the picture. In the mixed air setpoint manager, I am supposed to set the fan inlet and outlet node. However, these nodes are internal to the unitary system and not visible to me in the diagram. In this situation, is there a way to know the node names? and do they even show up in the node selection drop down list?
