[Problems to be Solved by the Invention] In the above-described conventional technology, the function settings of the indoor unit are performed with a setting device attached to the indoor unit, and the function settings of the outdoor unit are performed with a setting device attached to the outdoor unit. However, since the indoor unit and outdoor unit are installed in separate locations, when specifying or changing functions, it is necessary to travel back and forth between the separate locations, which poses the problem of lack of serviceability and promptness of construction work. . Furthermore, since the indoor unit is installed on the ceiling or the like, it is necessary to go into the ceiling to set its functions, which makes it difficult to set the functions.

Furthermore, since outdoor units are installed on rooftops where people usually do not enter, it is necessary to go there to set up the functions, which is not only troublesome but also poses safety issues.

An object of the present invention is to provide an air conditioner with a remote control that allows function settings of an indoor unit and an outdoor unit to be easily and quickly performed.

[Means for Solving the Problems] The above purpose is to specify functions of the indoor unit and functions of the outdoor unit in an air conditioner composed of an indoor unit and an outdoor unit, and to control each specified function to an indoor unit control device. This can be achieved by issuing a command to the outdoor unit control device via a communication means or by providing a remote controller.

The above purpose is to provide a display device connected to the indoor unit that specifies the functions of the indoor unit and the outdoor unit, and displays the specified functions in an air conditioner equipped with an indoor unit and an outdoor unit that exchanges heat between the indoor unit and the outdoor unit. an indoor unit control device that takes in designated data from the remote controller, sets the function of the indoor unit to the designated function, and transmits the designated data to the outdoor unit when the designated data relates to the outdoor unit; This can also be achieved by providing an outdoor unit control device that takes in specified data from the indoor unit control device and sets the function of the outdoor unit to the specified function.

[Effects] Since the configuration allows you to specify the functions of the outdoor unit and the function of the indoor unit to be set using one remote control, there is no need to go to the respective installation locations and set them. Functions can be set.

[Example code] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Hereinafter, the function setting procedure of the indoor unit and outdoor unit will be explained according to these flowcharts.

Assume that the room thermo function, which is one of the functions of the indoor unit, is set. In this case, the setter operates the setting device 3 of the remote control 6 to select the indoor unit function setting mode, and also specifies the function code corresponding to the room thermo function using the setting device 3 in this mode. The details of changing the outdoor unit specified by the setting device 3 are stored in the storage device 4 in the remote control 6 and displayed on the display 2. Further, this content is sent from the transmission mechanism 5 to the indoor unit control mechanism 11 via the control signal line 15.

In the indoor unit control mechanism 11, the transmission mechanism 8 receives the content sent from the remote controller 6, and first determines whether there is a function change instruction. If there is a function change instruction, then it is determined whether the instruction is to change the function of the indoor unit. If it is an instruction to change the function of the indoor unit, store the instruction contents in the memory bag M.
9 and executes indoor unit function change processing.

In this case, we will add a room thermo function and control the indoor unit.

When setting the height difference of piping, which is one of the functions of the outdoor unit, the outdoor unit function setting mode is selected using the setting device 3 of the remote controller 6, and the height difference of the piping in that mode is specified by a code. The outdoor unit function change contents input from the setting device 3 are displayed on the display 2 and stored in the storage device 4. Furthermore, this outdoor unit function change content is sent from the control signal line 15 to the indoor unit control mechanism 11 via the transmission mechanism 5.

In the indoor unit control mechanism 11, the transmission mechanism 8 receives the content sent from the remote controller 6, and first determines whether there is a function change instruction. If there is a function change instruction, then it is determined whether the instruction is to change the function of the indoor unit. Then, it is determined whether or not the first function change instruction is to change the function of the outdoor unit. In this case, since the function of the outdoor unit is changed, the received outdoor unit function change is stored in its own storage device 9 and sent from the transmission mechanism 10 to the control signal line 16.

In the outdoor unit control mechanism 14, the transmission mechanism 12 receives the content sent from the indoor unit, and determines whether or not it is a function change instruction. If it is a single function change instruction, then it is determined whether the change instruction is directed to the outdoor unit. If the function of the outdoor unit is changed, the contents are stored in the storage device 13.
At the same time, the function change process is executed. In this case, the outdoor unit is controlled by changing the height difference of the piping.

According to the embodiment described above, the storage device 4 of the remote controller 6 stores the changes in the functions of the indoor unit and the outdoor unit, and the storage device 9 of the indoor unit also stores the changes in the functions of the indoor unit and the outdoor unit. , the storage device of the outdoor unit stores the function change contents of only the outdoor unit. In this way, by storing the same content in multiple storage devices provided at different locations, even if a failure occurs in any of the devices, it becomes easy to reconfigure the functions of the replaced device.

Each indoor unit control device has its own address, and in the flowchart of FIG. 5, address determination is first performed.

According to the embodiments described above, the functions of the indoor unit and outdoor unit can be arbitrarily set using one remote control 6, and there is no need to go to the installation location of the indoor unit or outdoor unit.

Furthermore, since settings are made using function codes, there is less risk of incorrect settings.

[Effects of the Invention] According to the present invention, the function settings of the indoor unit and the outdoor unit can be performed in one place where a remote control is installed, and function settings and changes are facilitated and serviceability is improved.
