ABSTRACT:
A variable air volume control system has a temperature system management device which calculates an air flow setpoint in a temperature zone as a function of a proportional term that accommodates gross temperature-setpoint errors, and integral term that provides heating or cooling load matching, and a derivative term that accommodates rapid fluctuations in the cooling or heating load, and communicates the flow setpoint to a terminal control unit to adjust the air flow to a space. The terminal control unit will implement a flow setpoint as a function of the gross error in temperature in the space and a default temperature comfort setpoint upon failure of the temperature system management device to maintain a temperature in the zone.
