That is, after starting, in step S 1 , it is determined whether or not it is permissible to transmit operation information from the indoor unit (A) of the master unit by the outdoor control unit (1), and only when permissible transmission is performed in step S 2 suspended during transmission from the machine (a) determines whether or not (OFF time) or, since initially there in situations where there to the transmission permitting state is transmitting the operation information, in step S 3, the operation information It is determined whether or not the driving information received by the indoor reception unit (6) at the time of transmission of the information matches the transmitted driving information, and the driving information does not match (that is, the two remote control devices (D) are (For example, (A) and (B)) connected to the base unit 2
In the case of a connection failure that has become a base, each master unit ((A) and (B))
When it is detected that the driving information from the vehicle overlaps and a collision occurs, and its own driving information has priority information (for example, an indoor unit anti-freezing operation command signal or a drain abnormality signal), that is, when the collision detection is won. the, to continue the transmission of its own operation information, the process returns to clear the counter for a connection failure detection of the remote control device (abnormality counter) to zero value the routine proceeds to step S 10.

Therefore, according to the determination flow of FIG. 5, the driving information received by the indoor receiving unit (6) when the driving information is transmitted from the outdoor transmitting unit (5) is the same as the driving information transmitted from the transmitting unit (5). When they do not match (when a collision is detected), the transmission of the driving information of the self device is stopped unless the priority information is previously stored, and in this state, the address designation of the master device is performed a predetermined number of times (
If it continues more than once, at this time, the transmission unit (the connection abnormality signal indicating that a plurality of remote control devices (D) are connected to the indoor units (for example, (A) and (B)) is used as the operation information.

Therefore, in the above embodiment, from the indoor unit (A) as the master unit to which the remote control device (D) is connected,
Along with signals such as a self-freezing prevention command and drain abnormality, the indoor temperature and timer time determination signals representing all the indoor units (A) to (C) as operation information from the indoor transmission unit (5) to the outdoor unit (X). ) Is transmitted to the outdoor unit (X), the indoor temperature and the timer time signal from the indoor unit (A) of the parent unit are received by the outdoor receiving unit (3), and the operation control signal based on these is received outdoors. Since the transmitter (2) transmits to the indoor units (A) to (C), the indoor unit (A) to which the remote control device (D) is connected.
As the master unit, the indoor units (B) and (C) of the other slave units are grouped into the same operating state according to the determination operation of the indoor unit (A) of the master unit. Controlled.

Now, in the normal case where only a single remote control device (D) is provided for all the indoor units (A) to (C), when the address of the parent device is specified, the parent device (A) outputs its own driving information. Since only the indoor reception unit (6) of the indoor unit receives the operation information transmitted by itself, the abnormality determination unit (15) does not operate, and the indoor transmission unit (5) does not operate the remote control device. The connection abnormality signal of (D) is not transmitted.

On the other hand, when two remote control devices (D) are abnormally connected to all the indoor units (A) to (C), the two connected indoor units (for example, (A) and (B)) As the master unit, each indoor reception unit (6) receives its own driving information and the driving information from other master units when transmitting the driving information from its own indoor transmission unit (5). Then, the driving information collides with each other, and the driving information received by the indoor receiving unit (6) does not match the driving information transmitted from the indoor transmitting unit (5). Then, the indoor unit (for example, (B)) on the side having priority information such as the freeze prevention command and the drain abnormality continues to transmit, and the other indoor unit (for example, (A)) transmits the operation information. If the transmission is forcibly stopped and the transmission is stopped a predetermined number of times (four times) or more thereafter by address designation of the master unit, the abnormality determination unit (15) operates at this point and the remote control device (D The connection abnormality signal of 4) is transmitted from the transmission unit (5) as operation information. As a result, for example, all indoor units (A)
The operation of (C) is forcibly stopped, or the abnormal connection of the remote control device (D) is evoked to the person in the room, and the malfunction of the device is effectively prevented.
