That is what I thought. So in the System Browser, I should have my air handling unit as mechanical system 1 (for example). Below that, I should have all of the FPBs and VAVs associated with that air handler listed. Then I will have mechanical systems 2, 3, 4, 5, etc. for each FPB/VAV with the associated air terminals below those. Makes sense, just wanted to make sure I understood the process.
