5 REGIONAL CONTROLLER
5.1 Function
Region monitoring control and region wired control are the two main control functions for region 
controller.
Region monitoring controller can monitor or control 16 indoor units of a group for inquiry and single or 
centralized control.
Region wired controller can replace 1-16 selected wired controllers to uniformly set or control the indoor 
units.
Refer to Fig.5.1.1, Fig.5.1.2 about the Sketch map to the relation among the region controller, region 
monitoring controller and region wired controller.

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.
