Problems solved by technology
[0010] However, in conventional air conditioners, during address setting, for example, when a reception abnormality occurs due to signal disturbance such as interference or oscillation, it is necessary to go back to the first bit and perform address setting again, so there is a need for address setting. long time problem
In addition, if the signal disturbance continues to occur, the address setting will not be possible due to the same reception error occurring during the resetting of the address.

Embodiment Construction
[0039] 1st embodiment
[0040] figure 1 It is a schematic configuration diagram showing the air conditioner according to the first embodiment of the present invention. An air conditioner 100 according to the first embodiment includes one outdoor unit 10 , a plurality of indoor units 21 to 24 , and a remote controller 30 . The outdoor unit 10 and the indoor units 21 to 24 can communicate with each other through the communication line 40 , and the remote controller 30 and the indoor units 21 to 24 can communicate with each other through the communication line 50 .
[0041] Since the outdoor unit 10 needs to send and receive control signals for controlling the operations of the compressors and fans with the plurality of indoor units 21 to 24 during normal operation, it is automatically performed before the normal operation. The address setting operation of the address.
[0042] In addition, since the remote controller 30 also transmits control signals for controlling the wind ...

An air conditioner is provided with the features that address setting time is shortened and the address setting is accurately carried out. A serial number detecting unit (11a) transmits a first digit detecting instruction to a plurality of indoor devices (21-24) with multiple addressing and, when there is no response to the detecting instruction, the serial number detecting unit (11a) transmits an instruction to request a second digit, one digit before the first digit, to a plurality of indoor devices (21-24) with multiple addressing. That is, without returning to the original digit of the serial number, the address setting is redone from its one previous digit, so that address setting can be shortened. Further, when the address setting is carried out from the one previous digit and if a method for recognizing detecting instructions in the indoor devices (21-24) is changed, the address setting can be done more accurately.
Description
technical field [0001] The invention relates to an air conditioner and an address setting method of the air conditioner, in particular to the technology of setting addresses for a plurality of indoor units. Background technique [0002] When a plurality of indoor units are controlled by one outdoor unit, addresses for sending control signals to the respective indoor units need to be set in advance. The same is true when sending control signals to multiple indoor units with one remote controller. [0003] In conventional air conditioners, the outdoor unit or the remote controller requests the serial number unique to each indoor unit bit by bit, and the indoor unit detects the serial number in response to the requested bit number, thereby identifying the indoor unit with the serial number. Make address settings. [0004] During address setting, for example, if the indoor unit cannot normally receive the command requesting the specified bit of the serial number due to interfe...
