PURPOSE: To provide a wireless remote controller for air-conditioning machine, which is capable of controlling individual air conditioning machine in the network of air-conditioning machines selectively.

CONSTITUTION: Respective air-conditioning machines A, B transmit address data, representing the address of the air-conditioning machine itself, in synchronizm with a polling from a network control instrument. When a wireless remote controller 1 receives an address data from the air-conditioning machine A, the address is displayed on a display screen 1a. During this period, when a transmission button is pushed by an operator, a wireless remote controller 1 transmits control data, added with an address data in reference to the air- conditioning machine A, to the air-conditioning machine A. Two-way communication is permitted by detecting the address of respective air conditioning machines automatically by the wireless remote controller 1 and coping with the air-conditioning machine, which is the object of control, by 1:1 in such a manner whereby individual air-conditioning machines are permitted to be controlled selectively.
