INDOOR UNIT FUNCTIONS

Air distribution
Automatic air-speed adjustment
PLFY EM PLFY
PCFY KM PKFY
An automatic Air-speed mode automatically adjusts airflow speed to maintain comfortable room conditions at all times.
This setting automatically adjusts the air speed to conditions that match the room environment.
The unit operates at high speed at startup to rapidly
heat or cool the space, then automatically slows
down once the target temperature has been reached.
It is more economical than starting up the unit at low
speed and keeping it operating at low speed.

A maximum of four fan speeds are available (Low-Middle 2-Middle 1-High). In addition to the four fan speeds, the Auto
mode is available on some models. Various combinations of fan speed and vane angle setting are available to create the
optimum airflow for any given space.

*The actual fan speed will differ from the fan speed displayed on the LCD when one of the following conditions is met.
• While "Standby" or "Defrost" is displayed
• When the room temperature is higher than the set temperature during the heating mode
Vane setting
PLFY EM PLFY
Vertical airflow setting is selectable from a maximum of seven settings (a maximum of five fixed angles, swing, and Auto).
Using different combinations of vertical airflow setting and fan speed, airflow direction and distance can be fine-tuned to
deliver optimum airflow to all corners of the room.
When set to Auto, the vane is directed horizontally in the Cooling, Dry, and Fan modes, and directed downward in the
Heating mode. The available vane angle positions will depend on the remote controller to be used. Refer to the
instruction manual of the relevant remote controller for details.
Swing
PLFY EM PLFY
The air outlet vane swings up and down so that the airflow is spread evenly
throughout the room.
*The actual air direction will differ from the air direction displayed on the LCD when one of the following conditions is met.
• While "Standby" or "Defrost" is displayed
• When the room temperature is higher than the set temperature during the heating mode
• Immediately after heating operation (during standby for switching the operation mode)

Air speed is automatically reduced when the
target temperature has been reached, saving on
energy costs. There is no more need to
remember to turn down the setting.
