Abstract
The variable air volume ventilating system includes a control device for driving a fan at continuously variable speeds for delivering air to the space for conditioning purposes. A controller monitors various conditioners of the space, to, in turn, cause the control device to drive the fan at different continuously varying speeds. A light conduit, such as a fiber optic link, interconnects the control device and the controller for supplying a control signal to the control device.
