くように構成したものである。In order to achieve the above object, the present invention has means for determining that a unit that receives a transmission signal from an outdoor unit is a master unit, and a unit that does not receive a signal as a slave unit. It is configured to run software that steals the data being sent.
室内ユニットは電源投入時一定時間、室外ユニットから
の伝送信号を持ち、信号有りならば親機、信号無しなら
子機と認識する。The indoor unit has a transmission signal from the outdoor unit for a certain period of time when the power is turned on, and if there is a signal, it is recognized as a master unit, and if there is no signal, it is recognized as a slave unit.
子機は室外ユニットとの情報交換は行なわずにリモコン
との情報交換のみ行なう。The handset does not exchange information with the outdoor unit, but only with the remote controller.
新機は室外ユニットとの情報交換を行ないながらリモコ
ンとの情報交換を行なう。また、子機とリモコンとの情
報をスチールし、子機の運転状態を認識する。The new machine exchanges information with the remote control while exchanging information with the outdoor unit. It also steals information between the slave unit and the remote control, and recognizes the operating status of the slave unit.
この様に動作するので室外ユニットは室内ユニットのい
ずれと接続してもよく、室内ユニット間の接続も簡単で
施行 まいが少なくなる。Since it operates in this way, the outdoor unit can be connected to any of the indoor units, and the connection between indoor units is also simple and requires less effort.
以下、本発明の一実施例を第１図ないし第３図により説

。First, FIG. 1 will be explained. The remote control 1 is connected to the indoor unit 3 via the connection wiring 5. It is serially connected to the indoor unit 4 via connection wiring 6. The indoor unit 3 is connected to a transmission circuit 3B for exchanging information with the remote control 1, a transmission circuit 3C for exchanging information with the outdoor unit 2 via connection wiring 7, and transmission circuits 3B and 3C to control the indoor unit 3. It is composed of a microcomputer control section 3A that performs the following operations.
室内ユニット４も全く同じ構成である。室外ユニット２

２Ａより構成される。The indoor unit 4 also has exactly the same configuration. outdoor unit 2
It is composed of a transmission circuit 2B that exchanges information with the indoor unit 3 or 4, and a microcomputer control section 2A that controls the outdoor unit 2.
第２図より親子判別方法を説明する。室内ユニットは電
源投入時より室外ユニットからの伝送信号を待ち、伝送
信号を受信すると室内ユニットを親機と判別し、伝送信
号を一定時間受信しない場合はその室内ユニットを子機
と判別する。The method for determining parentage will be explained with reference to FIG. The indoor unit waits for a transmission signal from the outdoor unit when the power is turned on, and when it receives the transmission signal, it determines that the indoor unit is the master unit, and if it does not receive the transmission signal for a certain period of time, it determines that the indoor unit is the slave unit.
第１図と第３図より冷房運転制御を説明する。Cooling operation control will be explained with reference to FIGS. 1 and 3.
室内ユニット３は室外ユニット２と接続配線７を介して
接続されており、親機となる。室内ユニット４は室外ユ
ニット２と接続されておらず子機となる。The indoor unit 3 is connected to the outdoor unit 2 via a connection wiring 7, and serves as a master unit. The indoor unit 4 is not connected to the outdoor unit 2 and becomes a child unit.

る場合は運転指令を送信する。When the main indoor unit 3 receives the cooling operation command from the remote controller 1, it checks whether the temperature controller is operating using the control unit 3A, and if it is not operating, outputs a stop command to the outdoor unit 2 via the transmission circuit 3c. do. If it is operating, it checks the operation of the temperature controller of the indoor unit 4, and if it is not operating, it sends a stop command to the outdoor unit 2, and if it is operating, it sends an operation command.
すなわち、室内ユニット３はリモコンからの冷房運転指
令があり、室内ユニット３，４の温度調節器が共に作動
