PROBLEM TO BE SOLVED: To search a cause of a fault of air conditioner and air conditioner relating devices and to display necessary air conditioning information by providing a fault analyzing means for analyzing the fault occurring in the device of an air conditioning system. SOLUTION: First, a normal drive operation mode is switched to a communication inspecting mode by a remote control operation unit 3e. Then, an address of an air conditioner for executing a communication inspection is set from the unit 3e. A communication state verify command previously stored in a remote controller memory 3b is transmitted to a controller (1c or 2c) of the conditioner through a signal transmitter/receiver 3a. Then, if the conditioner is normal, the controller (1c or 2c) of the conditioner returns communication state information, and a remote controller 3c decides whether the communication is normal or not. A remote controller display 3d displays 'normally operable', 'abnormal communication' or the like in response to the decided result. Accordingly, the fault of the communication state can be analyzed. |
