The special determination mode request button 6i has a function of displaying gas leak detection start and gas leak detection confirmation.

  Next, the operation of the first embodiment will be described. In the case of air conditioner maintenance or after-sales service, for example, when it is desired to check the compressor operating current, the switch 6k for switching between the normal test operation mode and the maintenance / after-service mode, which is normally used for test operation, is used for a certain period of time. Press and hold for 3 seconds to enter maintenance / after-sales service mode. First, in order to stabilize the operation state of the air conditioner and facilitate the determination of the quality of the acquired data, the cooling code stable operation is selected and transmitted to the air conditioner by the request code setting means 1c by the operation of the remote controller 1. Specifically, when the special operation request button 6d that is the operation switching button of the remote controller 1 is pressed and the display is switched to the display of the ray bow on the dot liquid crystal display section 6a, a request code normally used for a filter is transmitted. The special operation request code is transmitted to the indoor unit 2 by pressing the button 6h. The transmission data includes information that the destination is the outdoor unit 3 and the request type is a special operation request. The indoor unit 2 that has received the request determines that the request destination is the outdoor unit 3 by the indoor unit request destination determination unit 2d and relays the request to the outdoor unit 3 by the indoor unit second transmission / reception unit 2e.

  The outdoor unit 3 is determined to be a special operation request by the outdoor unit request type determination unit 3f, and the outdoor unit operation output control unit 3h is used to fix a control parameter such as an operation frequency of a compressor (not shown). Start operation. When the state of cooling stable operation, which is a special operation request, is stabilized to the remote controller 1 via the indoor unit 2, information indicating that it is stable is transmitted to the display unit 6 so that the display control means 1b of the remote controller 1 shows that it is stable. Do. Specifically, the display is such that the blinking of the symbol displayed on the set temperature display portion 6b of the remote control liquid crystal display changes to lighting. The user confirms the stable display, and selects and sets the code assigned to the compressor current from the request code table shown in FIG. 2 stored in the control unit of the indoor unit 2 or the outdoor unit 3 by the request code setting means 1c. To do. For the setting, not the code number on the display unit 6 of the remote controller 1, but for the sake of easy operation, for example, as shown in (b) compressor information button as shown in FIG. Display such as “Kidden Ryu (A)” that makes it easy to understand the contents of the requested data and its unit amperes may be performed. Specifically, when the first operation data (compressor) button 6e, which is normally used as a timer menu, is pressed and the display "Pressure pressure (A)" is displayed on the remote control dot liquid crystal display 6, the filter button When the request code transmission button 6h is pressed, the request code corresponding to the content is transmitted to the indoor unit 2. Setting in the request code number is impossible during the maintenance mode, and by restricting the setting to only a specific request code, a complicated operation may be eliminated, and a wider range of air conditioners may be able to perform the maintenance operation. The indoor unit 2 that has received the compressor current data acquisition request determines that the destination is the outdoor unit 3 and transfers it to the outdoor unit 3. The outdoor unit 3 is determined to be a data acquisition request by the outdoor unit request code type determination unit 3f. The data is acquired by the outdoor unit data input control means 3g and returned to the remote controller 1 via the indoor unit 2, and the current value is displayed on the remote controller display unit 6. Specifically, when “15” is displayed on the time display portion 6c of the remote control liquid crystal, it indicates that the compressor current value of the outdoor unit 3 is 15 amperes. When it is desired to acquire various detailed service data, the request setting mode may be entered by operating a button different from the maintenance data acquisition.

  For example, while in maintenance mode, press and hold the maintenance mode / after-service mode switch button 6l normally used for inspection for 3 seconds to switch to the after-service mode. In this mode, more detailed failure analysis In order to read out a variety of data by a more professional service person for the purpose of, for example, the above-mentioned request code setting operation, a code number is normally set cyclically with a button used for time setting. The explanation display corresponding to the number is not performed on the dot liquid crystal display section 6a. All the request code setting operations are performed only by numbers, and all request codes can be transmitted without setting restrictions on the range of numbers that can be set.

  Further, in order to make it easier for the user to know the repair contact information when the air conditioner breaks down, for example, when the air conditioning equipment supplier who has performed the installation work installs the special operation operation request button 6d which is an operation switching button. If you enter the phone number for repairs on the phone number input screen by button operations that are not normally used by the user, such as pressing the first operation data (compressor) button 6e, which is the timer menu button, at the same time. The information is stored in the memory in the remote controller 1, and in the event of a failure, for example, in the case of an abnormal installation sensor, the dot liquid crystal display unit 6a displays the abnormal code P1 displayed conventionally and the telephone stored in the memory. Display such as number display CALL-01234456789 is blinked alternately. As a result, there is an effect that operations such as maintenance or after-sales service or repair work can be promptly handled without causing the customer to wait.

  Next, I will explain the special button operation for multi-language selection. First, a plurality of buttons including a special operation request button 6d that is an operation switching button of the remote controller 1 and a second operation data (outdoor) button 6f that is a timer ON / OFF button are simultaneously pressed for 3 seconds to display the dot liquid crystal display 6a. The multilingual conversion screen is displayed. In this state, the first operation data (compressor) button 6e, which is a timer menu button, is pressed to select the required language from among the eight languages stored in the control unit, and finally the special operation operation which is the operation switching button again. If you press multiple buttons, the request button 6d and the second operation data (outdoor) button 6f, which is a timer on / off button, for 3 seconds at the same time, the setting is completed and users of other nationalities are expected. Or in a public building where multinational people gather, for example, Japanese, English, German, Spanish, French, Italian, Russian, Chinese, etc. can be displayed.
