When two or more air conditioners are installed in a room and the remote controller is oper-
ating an air conditioner other than the one you wish to set, change the custom code of the
remote controller to operate only the air conditioner you wish to set (4 selections possible).

the air conditioner cannot receive a signal if the air conditioner has not been set for the
matching custom code.)
