10 Operation Details (Functions & Protection)
10.1. Simultaneous Operation Control
1. Operation modes which can be selected using the remote
control unit: Automatic, Cooling, Soft Dry, Heating, Fan operation
2. Types of operations modes which can be performed
simultaneously

3. Types of operation modes which cannot be performed
simultaneously


·

While a cooling operation is in progress, a heating operation
cannot be performed by an indoor unit in another room.
In the room where the operation button for cooling was pressed
first, the operation is continued. In the room where the operation
button for heating was pressed afterward, the operation lamp of
the indoor unit blinks, where the attempt is made to establish the
heating operation. Its fan is stopped, and the air does not
discharged.

·

If the priority indoor unit stops operation or initiates the fan
operation, the priority is transferred to other indoor units.
“Waiting” denotes the standby status in which the operation
lamp LED blinks (ON for 2.5 sec. and OFF for 0.5 sec.), and
the fan is stopped.
* In the fan mode, priority is transferred to a non-priority unit.
