A control for an induction air mixing box for mixing conditioned primary air and induced secondary air for delivery at a substantially constant volume rate of flow into a condition controlled space, the volume rate of flow of primary air being maintained constant at a predetermined rate, said predetermined rate being resettable as a function of the sensed condition in the space. The induced rate of flow of secondary air is restricted as another function of the sensed condition, the change in rate of flow of the secondary air being inverse to that of the primary air. |
