volume of space. The primary function of an HVAC Zone
is to "manage" the operation of each individual HVAC
unit by providing the temperature setpoints that will be
used in Temperature Control. Zones are also responsible
for ordering HVAC units to dehumidify and determining
when outside air conditions are favorable to economize.
