Enabled only in mini VRF System heat-pump models.
<Function>
With indoor units that are installed in combination with an outdoor unit model where either heating or cooling 
operation can be selected, the operating mode of the indoor unit that starts first takes priority. The first indoor unit 
to operate can select any operating mode. When any mode other than fan mode is selected, then the operating 
modes that cannot be selected are not displayed on all remote controllers that are subsequently operated. 
“Operation change control in progress” is displayed, indicating that there are restrictions on the operating  
modes that can be selected.
•
Controlling the operating mode from a specific remote controller
-  When there are multiple remote controllers in the same refrigerant system, it is possible to set one remote 
controller as the priority remote controller (the remote controller which is given priority for selecting the 
operating mode). (If 2 or more remote controllers are set as priority remote controllers, an alarm will occur at 
the remote controllers, and operation will not be possible.)
-  When the priority remote controller is set to the operating mode for control, then all other remote controllers can 
select only the permitted operating mode, regardless of whether the priority remote controller is operating or 
stopped.
-  When a controlled remote controller is operated, “Operation change control in progress” is displayed.
Set mode at priority remote controller Modes that can be selected at other remote controllers
Cooling or dry Cooling, dry, fan
Heating Heating, fan
Fan Whichever mode (heating/cooling) is selected first
NOTE
There are other methods to avoid control in which the mode selected first takes priority. 
 
Methods of remotely controlling the operating mode
(1) Use the central functions of a central control device.
(2) Use a remote control relay PCB at the outdoor unit.
