Multiple terminal units in one thermal zone in OpenStudio

edit

First Question: I would like to have one thermal zone for the whole south side of the building serving 8 conditioned spaces with one terminal unit in each of these spaces. How could I do that?

Second Question: If I had a very large space like a whole story open office of a 400m^2 area and having assigned it into one thermal zone, how could I have 8 terminal units on this space?

As regard the second question, the reason I want 8 terminal units in one thermal zone is because I think the results (between 8 and 1 terminal unit) are totally different in many ways.

Specifically:

1. One terminal unit doesn't have the same comfort results across all the space area (in a 200m^2 area), for example if I put the terminal unit in the south side of the space, definitely a person in the north side will not have the same sensible comfort result
2. One terminal unit doesn't consume the same energy as 8 terminal units.

If I made a mistake, please let me know.

This is REALLY very strange. I give an example: Let's suppose i assign 5 different spaces(this means that there are walls between them) into one thermal zone. How can these 5 spaces be serviced by ONLY ONE terminal unit ? There must be an option of assigning number of terminal units for heating/cooling of a space. If no, logic says that i have to assign one distinct thermal zone for each of my spaces that i want to be serviced! Can someone more experienced than me in OpenStudio answer my question?
