Priority Room Setting
The Priority Room Setting requires initial programming during installation. Please consult your
retailer or dealer for assistance.
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.
〈
Example
〉
* Room A is the Priority Room in the examples.
When COOL mode is selected in Room A while operating the following modes in Room B,C and D:
2. Priority when POWERFUL operation is used.
〈
Example
〉
* Room A is the Priority Room in the examples.
The indoor units in Rooms A,B,C and D 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 Rooms B,C and D may be slightly reduced.
3. Priority when using OUTDOOR UNIT QUIET operation.
〈
Example
〉
* Room A is the Priority Room in the examples.
Just by setting the unit in Room A to QUIET operation, the air conditioner starts OUTDOOR UNIT
QUIET operation.
You don’t have to set all the operated indoor units to QUIET operation.
When the simultaneous operational capacity is
exceeded
If the simultaneous operational capacity is exceeded for outdoor unit capacity, the indoor unit
enters Standby Mode, and the operation light flashed; this is not a malfunction.
<Example>
When the units in rooms A, B, and C are being used, and the D is used, causing an overload:
The room (from A to D) which is closest to the set temperature will go into standby mode. The
room in standby mode will resume operation once operation in the other rooms is stopped.
