Before using, the controller functions must be selected by the personnel who performance the installation with
the requirements of users. Please refer to Project Debugging Setting section for the details.
Note: If the controller is set to be region wired controller, the wired controller of the selected indoor unit
must be removed.
The region controller can be matched with long-distance monitor. As a region monitoring controller, its control
is subject to that of the long-distance monitor. In the same group, one of the region controllers can be used as
region monitoring controller and matches one or more region wired controller which replace(s) one or more wired
controller, in which case, the region monitoring controller can also monitor or control the region wired controller.
