FIG. 2 is a flowchart showing the initial operation of the control section of the outdoor unit 1 shown in FIG. 1, and is as follows. First, the number N of indoor units (or the same number of remote controllers) to be connected to the outdoor unit 1 is set. Next, a control signal of command A (command to cut off the power supply to the connected remote controller) is sequentially transmitted to all indoor units according to the flowchart. In this procedure, first, "command A" is sent to the indoor unit specified by address A10, and after receiving a control signal "command B" (return signal from the indoor unit) from this indoor unit, the next indoor unit is sent. to “Command A”
Send. The subsequent transmissions are performed in the same manner. still,
If the outdoor unit 1 does not receive the "command B", it restarts from "start" after a predetermined period of time, and if this restart reaches 3N times, the air conditioner is determined to be abnormal and displays an abnormality display. The addresses of the indoor units are A10, A20...A(no)...A

First, the outdoor unit 1 and indoor units 2 and 3 are powered on. As a result, the outdoor unit 1 transmits a control signal of "command A" to the indoor units 2 and 3 to cut off the power supply to the remote controllers 4 and 5. Next, the outdoor unit 1 sends a command control signal to the indoor unit 2A10 to start supplying power to the remote controller 4. Next, send the control signal D11 (=10+01) to the remote controller 4 (address A (01)). At this time, the remote controller 5 does not operate because power is not supplied.Therefore, the remote controller 4 changes the address to A11 based on this data D11.Next, the outdoor unit 1 transfers the address to the indoor unit 3.
A "command" control signal is transmitted to the remote controller 5 to start power supply to the remote controller 5. Next, a control signal D21 (=20+01) is transmitted to this remote controller 5 (address A (01)). At this time, the address of the remote controller 4 has changed to A11, so there is no interference. Therefore,
The remote control 5 changes the address to A21 based on this data D21.

(G) Effects of the Invention As described above, the control method of the present invention is capable of controlling the address setting for specifying signal transmission and reception between each unit in a multi-type air conditioner, especially the address setting of the remote control from the outdoor unit to the indoor unit. The indoor unit that receives the control signal controls the power supply to the remote control attached to the indoor unit based on the control signal.
The remote control that receives the control signal changes its address to the address related to the indoor unit to which it is attached.
The final address of the remote control is set in relation to the indoor unit after the remote control is connected to the indoor unit. In other words, even if this remote control is connected to any indoor unit, no erroneous connection occurs and the versatility of the remote control is improved.
