Improvement of Energy-Saving through the new Indoor Unit and Remote Controller
New RCI-(1.0-6.0)FSN3 - 4-way cassette and two optional air panels offer the following benets:
Benets Outline
Improvement of Energy Saving
(1) The high performance heat exchanger, the highly efcient
turbo fan and the new DC drain pump are adopted.
(2) Energy saving is improved by the air panel with motion sen-
sor.
Improvement of energy saving by newly developed heat ex-
changer and turbo fan, and by adoption of motion sensor.
Adoption of New Structure Silky Flow Louver Attenuation of the discomfort that might be caused by tempera-
ture irregularity and cold draft.
Flexibility of Installation to High Ceiling Addition of air ow volume “HIGH H”, which is larger than “HIGH”.
Drain Pan: Adoption of New Antibacterial Agent and Larger Diam-
eter of Drain Plug
Inhibition of slime generation, and improvement of maintainability.

Adoption of High Performance Heat Exchanger, High Efcient Turbo Fan and New DC Drain Pump
The adoption of the high performance heat exchanger with small diameter pipe (f5mm), the turbo fan with 3D twisted blade
and the electrical power saving drain pump with DC motor allows high energy-saving operation.
Improvement of Energy-Saving Operation by Adopting Air Panel with Motion Sensor
- Adopting Motion Sensor Function
 The motion sensor function can adjust the setting
temperature according to the human activity, and it
controls the air ow volume and the air ow direction.
 Energy-saving is improved by combining the motion
sensor function and the individual operating function,
compared with the standard operation.

of Corner
Motion Sensor
The air conditioning capacity is regulated automatically depending on the situation and detecting the amount of human
activity through the motion sensor located on the corner of the air panel.
Energy-saving can be improved even more with the individual operation function. In addition, the operation can be stopped
automatically if absence continues for more than 30 minutes.
The motion sensor allows maintaining the comfortable indoor environment and supressing the unnecessary operation.
The motion sensor control adjusts automatically the following items depending on the situation:
• Setting temperature: is adjusted by 1ºC or 2ºC for energy saving
• Air ow volume: is adjusted to one volume lower or to “Slo” (except during the dry operation).
• Air ow direction: is adjusted to horizontal.
Effect of Energy-Saving by Motion Sensor
In the case of motion sensor being set as “ON” by the remote control switch and comparing with the temperature setting
before adjusting the operation as shown below (at cooling mode):
• The power consumption can be reduced max 7% by 1
o
C increase adjustment.
• The power consumption can be reduced max 14% by 2
o
C increase adjustment.
