Claim 11:
12. A method for heating, ventilating, and air conditioning a building having a plurality of zones, the zones being maintained at one or more temperatures, each zone having at least one terminal unit and at least one air quality sensor, the HVAC system comprising:
providing a cold air airstream for distribution in the building, and a cooling circuit ambient air damper for admitting ambient air into the cold air airstream;
providing a bypass air airstream for distribution in the building, independent of the cold air airstream, and a bypass circuit ambient air damper for admitting ambient air into the pass air airstream;
determining a hot ambient air condition, where the temperature of the ambient air is higher than the one or more temperatures maintained in the zones; and
closing the cooling circuit ambient air damper, and using the bypass circuit ambient air damper for admitting sufficient air into the bypass air airstream to ensure that the terminal units can provide for variable amounts of air as needed to Satisfy the respective air quality sensors, in response to the hot ambient air condition.
