3.1. Turning ON/OFF
Note:
Even if you press the ON/OFF button immediately after shutting down
the operation is progress, the air conditioner will not start for about three
minutes. This is to prevent the internal components from being damaged.
3. Operation
3.2. Operation mode select
Cool/Dry/Fan/Heat/Automatic (cool/heat)/Ventilation modes are
available.
Note:
Heat and Automatic mode can not be available for cooling only units.
Ventilation mode: only indicated on the following condition. Wired remote
controller is used and LOSSNAY is connected.
Automatic mode
According to a set temperature, cooling operation starts if the room
temperature is too hot and heating operation starts if the room
temperature is too cold.
During automatic operation, if the room temperature changes and
remains 2 °C or more above the set temperature for 15 minutes, the
air conditioner switches to cool mode. In the same way, if the room
temperature remains 2 °C or more below the set temperature for 15
minutes, the air conditioner switches to heat mode.
Because the room temperature is automatically adjusted in order to
maintain a fixed effective temperature, cooling operation is performed
a few degrees warmer and heating operation is performed a few
degrees cooler than the set room temperature once the temperature is
reached (automatic energy-saving operation).

3.3. Fan speed setting
Note:
The number of available fan speeds depends on the type of unit
connected.
In the following cases, the actual fan speed generated by the unit will differ
from the speed shown the remote controller display.
1. When the unit is in “STAND BY” or “DEFROST” states.
2. When the temperature of the heat exchanger is low in the heat mode.
(e.g. immediately after heat operation starts)
3. In HEAT mode, when room temperature is higher than the temperature
setting.
4. When the unit is in DRY mode.
3.4. Airflow up/down direction setting
Note:
During swing operation, the directional indication on the screen does not
change in sync with the directional vanes on the unit.
Available directions depend on the type of unit connected.
In the following cases, the actual air direction will differ from the direction
indicated on the remote controller display.
1. When the unit is in “STAND BY” or “DEFROST” states.
2. Immediately after starting heater mode (while the system is waiting for
the operation mode change to take effect).
3. In heat mode, when room temperature is higher than the temperature
setting.
<[Manual] To Change the Airflow’s Left/Right Direction>
* The louver button cannot be used.
Model PKA-A·KA4
• Stop the unit operation, hold the lever of the louver airflow vanes, and
adjust to the desired direction.
* Do not set to the inside direction when the unit is in
the cooling or drying mode because there is a risk
of condensation and water dripping.
Caution:
To prevent falls, maintain a stable footing when operating the unit.
3.5. Ventilation
► For LOSSNAY combination
The following 2 patterns of operation is available.
• Run the ventilator together with the indoor unit.
• Run the ventilator independently.
Note: (for IR wireless remote controller and RF thermostat)
Running the ventilator independently is not available.
No indication on the remote controller.
4. Timer
Timer functions are different by each remote controller.
For details on how to operate the remote controller, refer to the appropriate operation manual included with each remote controller.
About the operation method, refer to the operation manual that comes
with each remote controller.
