PURPOSE:To make it possible to set a stable driving condition by setting a water temperature value between an extraordinary temperature determined by a predetermined external air temperature and a body thermostat possessed by a cool-warm water generator to stop a cool-warm water generator, in the case of using one primary pump. CONSTITUTION:A plurality of air conditioning apparatuses are remote-controlled by transmission means. In the case of using a single circulation pump on the heat source side, when the temperature of the air conditioning system reaches an outlet water temperature value of the air conditioning apparatus determined by a predetermined external air temperature, the air conditioning apparatus in operation is stopped even when the concentrated outlet water temperature of the air conditioning apparatus does not reach a predetermined set value. In a case where the minimum outlet water temperature of the air apparatus in operation determined by a predetermined external air temperature is higher than the temperature of a freeze preventing thermostat and the air conditioning apparatus stops its operation, a signal is emitted from a relay for multiplex transmission to a concentration controller through transmission means, and the restarting order of the air conditioning apparatus is made in such a manner that the restarting of the air conditioning apparatuses is carried out in the order from one having lowest workability successively to one having the highest.
