Abstract
In a VAV terminal local control loop including a bellows controlled orifice in which the bellows inflation is controlled by a bleed thermostat, a signal is produced indicative of terminal satisfaction/dissatisfaction which can be used in controlling the air handler. Specifically, the position of the opening in the bleed plate is detected and compared with the position of the bleed plate permitting the maximum amount of conditional air to be supplied by the terminal to the zone. A signal indicating whether or not the bleed plate is in the maximum bleed position is generated which can be used to furnish information for controlling the air handler.
