PROBLEM TO BE SOLVED: To provide an air conditioning system for selectively executing operation modes for heating operation in which a circulating fan is operated while supplying hot water from a water heater 51 to a heating unit and for air circulation operation in which the circulating fan is operated in the state of stopping the supply of the hot water, wherein a remote control device for the heating unit is connected to the water heater via a single communication line even when the plurality of heating units are arranged. SOLUTION: A circulation flow path D is formed which passes from the water heater 51 through parallel circuits of heating units 2, 4 back to the water heater 51. An operation mode selection part 63 is provided for a user to select the operation mode for each heating unit. The single remote control device 6 is connected via the communication line 61 to the water heaters. When the heating operation is selected for at least one of the heating units 2, 4, a hot water supply request signal is transmitted from the remote control device 6 via the communication line 61 to the water heater 51.
