Definitely you want to model it as a system per zone, using the Fan Coil system type (available in the detailed mode if not available out of the Wizard).
Fan Coils in eQuest don't bring in outdoor air, so by selecting this system type you should not have to worry about specifying zero OA. This also means that if you have any kind of energy recovery, it also won't work with a fan coil unit (because of no OA). If you wanted heat recovery you'd each system as a Single Zone Reheat system.
The heat source for your fan coils is obviously your hot water loop, and cooling from your chilled water loop, and you'd specify the efficiency/COP at the plant level. Your fans be modeled as two speed fans under Fan Control.

If you explicitly want to make heating only available for some months, and cooling for the other months, you'd put an availability schedule on the equipment for the relevant months.
