  • Subzone diverter control
    Patent number: 4527734
    Abstract: A zone whose air supply volume and character is responsive to temperature data supplied from a single location in the zone is made responsive to the requirements of a subzone remote from the sensor location. The air supply to the subzone is changed responsive to an unsatisfied condition therein resulting in a changed supply to the area in which the sensor is located. As a result, the sensor responds to the changed air supply by indicating an unsatisfied condition to which the system responds by changing the amount of air supplied to the zone.
