The room designated as the priority room takes priority in the following situations;
1. Operation mode priority.
As the operation mode of the priority room takes precedence, the user can select a different operation mode from other rooms.

2. Priority when POWERFUL operation is used.
< Example >
* Room A is the priority room in the examples.
The indoor units in rooms A and B are all operating. If the unit in room A enters POWERFUL operation, operation capacity will
be concentrated in room A. In such a case, the cooling (heating) efficiency of the units in room B may be slightly reduced.
3. Priority when using OUTDOOR UNIT QUIET operation.
< Example >
