41), if not, steps 142 to 143 are repeated.

Next, the indoor unit checks the remote control address stored in the address storage means 12 and searches for the minimum remote control address in order to determine the remote control for which the address is set (step 144). Each indoor unit checks whether or not another unit is transmitting on the transmission line 10 (step 145), and if there is a transmission signal, waits for a certain time (step 146) and checks the transmission line again. In step 147, the indoor unit transmits an address setting request signal to the remote controller with the minimum address (step 147) and waits for an address setting signal from the remote controller.

The address setting is received from the indoor unit, or the remote controller searches the indoor unit address of the address storage means 12 (step 161), recognizes the set indoor unit address, and then uses a prescribed method. The address of the indoor unit is determined (step 162). For the address determination, for example, a method of determining by using a rule such as “self-address of remote controller−minimum address of 100 or more and unset address” is used. Next, for the indoor unit of the temporary address,
The determined address is transmitted as an address setting signal (step 125), and the indoor unit address is stored in the address storage means 12 (step 126).

The indoor unit receives the address setting signal from the remote controller (step 148), changes its own address to the address designated by the signal (step 107), and stores the address in the address storage means 12 (step). 108). Next, the number of remote controllers stored in the address storage unit 12 is checked (step 149), and if the number of remote controllers is two or more, the address notification is transmitted to the remote controllers except the remote controller with the smallest address (step 150). .

In step 160, the address notification is received and the remote controller stores the indoor unit address in the address storage means 12.
(Step 126). The remote controller storing the indoor unit address checks whether or not another unit is transmitting on the transmission line for a certain period of time t2 or more, and if there is transmission to this remote controller, returns to step 160 (steps 163 to 166). If there is no transmission line for more than the time t2, the SW permission signal is transmitted to the connected indoor unit (step 167).

The indoor unit receives the SW permission signal (step 151) and turns on (passes) the signal switching means (SW).
Then (step 109), the address notification of the indoor unit is transmitted to the outdoor unit having the predetermined address (step 110). On the other hand, since the operation of the outdoor unit is the same as that of the first embodiment of claim 1, the description thereof is omitted.

Example 3. An embodiment corresponding to claim 3 will be described below with reference to the drawings. 6, description of the same reference numerals as those in FIG. 1 will be omitted. Reference numeral 20 is a ventilation unit that operates in conjunction with the operating state of the guide machine, and is connected to the second transmission line 10 of the interlocking indoor unit.
Particularly, the control means built in the indoor unit corresponds to the third control means. The address setting means incorporated in the indoor unit corresponds to the first address setting means, and the address setting means incorporated in the ventilation unit corresponds to the second address setting means.

Next, the operation will be described with reference to the flowcharts of FIGS. 7 and 8. Description of steps having the same numbers as in FIG. 2 is omitted. As the next step, the indoor unit that has received the address setting stores the address in the address storage means 12 (step 108), waits for a certain time (step 170), and another unit communicates on the transmission line 10. Check whether it is present (step 17)
1). When the power supply is turned on, the ventilation unit operating in conjunction with the indoor unit sets an address to a predetermined temporary self-address (step 180), receives an address notification from the remote controller (steps 181 to 182), and sends it to the transmission line. It is checked whether or not there is another unit communication (step 183), and the address setting request signal is received or transmitted to the remote controller address (step 184). On the other hand, the remote controller sets the address set in the address setting means as its own address (step 120), and reports the remote controller address to the temporary addresses of the indoor unit and the ventilation unit (step 200), and then the indoor unit or the ventilation unit. When an address setting signal is received from (step 122)
~ 123), the address of the indoor unit or the ventilation unit is determined by a prescribed method based on the remote control address (step 201). For the address determination, for example, a method of determining by using a rule such as “self-address of remote controller−minimum address of 100 or more and unset address” is used. Next, an address setting signal is transmitted to the indoor unit or ventilation unit having the temporary address (step 202), and the address is stored in the address determining means (step 20).
3). In step 204, it is judged whether or not the address setting request signal is received (step 204), and in the case of the address setting request, the process returns to step 201.

When the ventilation unit receives the address determined by the remote controller by the address setting signal (step 18)
5 to 186), the address is stored in the address storage means (step 187). When the indoor unit determines in step 171 that there is no communication on the transmission line, it transmits an interlocking setting request including the address determined by the remote controller and the first model identification means to the ventilation unit having the predetermined temporary address (step). 172). When the ventilation unit determines that the second model identification means has received the interlocking operation setting request signal among the received signals (steps 188 to 18).

Next, the operation will be described with reference to the flowchart of FIG. In step 220, the address change detection means 21 determines whether the address of the address setting means 7 has changed. If it is determined in step 220 that the address has been changed, the connected unit address relevant to the operation control in the memory of the address storage means 12 is searched (step 221). If there is a connected unit address (step 222), an address change permission request including a notification of the changed address is transmitted to all connected units (step 223), and the response is checked (step 224). If the response from all the connected units is permitted, the address change is notified to all the units (step 225), the self address is changed (step 226), and the address is stored in the memory of the address storage means 12. (Step 227).

On the other hand, when the unit connected to the unit whose address has been changed receives the address change request (steps 230 to 231), the changed address is temporarily stored in the address storage means 12 (step 232).
If the address can be changed, the address change permission is transmitted, and if the address cannot be changed, the address change impossible is transmitted (step 233). Next, when an address change notification is received from the address changing unit (steps 234 to 235), the memory of the address storage means 12 is rewritten to the address for changing the address of the unit for changing the address (step 236). Further, the address temporarily stored in the address storage means 12 is erased (step 237).

In the above description, the present invention is applied to the air conditioner, but it goes without saying that it can also be applied to communication means having other addresses.
