The setting contents of the operation unit 31 are transmitted to each indoor unit 1 (step 301). When the setting content is changed (YES in step 302), the changed content is transmitted to each indoor unit 1 (step 303).

When there is no reception from each indoor unit 1 (step
(NO in 304), at regular intervals (YE in step 315)
S), the setting content is transmitted to each indoor unit 1 (step 31).
6).

When there is a reception from each indoor unit 1 (YES in step 304), if the confirmation signal is included in the reception (YES in step 305), the set contents are transmitted to each indoor unit 1. (Step 306).

If the reception includes battery remaining amount information (YES in step 307), the remaining battery amount, which is the content of the information, is displayed on the liquid crystal display unit 32.

If the same setting command is included in the reception (YES in step 309), the same setting content is transmitted to the plurality of indoor units 1 (step 310).

If the operation signal (all stop command) based on the operation of the all system stop key 16 is included in the reception (YES in step 311), the operation stop command is transmitted to all of the indoor units 1. (Step 312).

When the data relating to the setting of the operation content is directly received by the receiving unit 33 from the wireless remote controller 6 (step 313), the received data of the operation content is transmitted to each indoor unit 1 (step 313). Step 31
Four).
