ABSTRACT:
A variable air volume ventilating system includes a fan volume modulator, for controlling a series terminal fan. A controller determines the proper fan motor speed, and generates a control signal which is transmitted to the fan modulator for varying the volume of the fan to be at least equal to the volume of the primary air available.
