    Abstract: A pneumatic system for controlling the temperature of a plurality of zones in an optimum manner. Each zone has a thermostat that controls a damper within the zone to regulate the flow of conditioned air to the zone to regulate the flow of conditioned air to the zone. The output of each thermostat is connected to a pressure selector, and the pressure signal representing the greatest deviation from the desired condition in a zone is transmitted to an optimizing relay that controls the conditioned air temperature. The relay is constructed and arranged so that in a warm air system the conditioned air temperature is not increased until the damper in the zone of greatest deviation has reached a maximum flow position.
