Abstract
The difference between the zone temperature and the scheduled setpoint, or .DELTA.t, is the basic data from each zone. Communication between the air handler control and the air terminal control is provided via the air system control so that the system is temperature, rather than pressure, responsive. The same temperature air is supplied to each zone in amounts sufficient for ventilation requirements independent of temperature requirements. The amount of air supplied beyond the ventilation requirements is controlled to achieve terminal satisfaction. The terminals are sampled to determined their satisfaction and their responses are requested as votes for either heating or cooling. Whether the system supplies heated or cooled air is determined by the voting.
