An induction ventilation system for one or more zones. For each zone, the system includes a heat exchanger, a means for driving a heating or cooling liquid through the heat exchanger, an adjustable flow rate primary air injector and a secondary air induction inlet, and a zone temperature control. The temperature control is selectively operative to control the injector to vary the flow rate of primary air in response to sensed temperature in the zone. The temperature control is further selectively operative to maintain the flow rate of the heating or cooling liquid to be relatively constant in one form of the invention, or to vary in response to sensed temperature in the zone in another form of the invention.
