control
1) Louver
position
This function controls the air direction of the indoor unit.
• The position is automatically controlled according to the operation mode (COOL / HEAT).
• The set louver position is stored in memory by the microcomputer, and the louver returns to the stored position
when the next operation is performed. (Cooling / heating memory position)
The angle of the louver is indicated as the horizontal angle is 0°.
When the louver closes fully, it directs approx. 10° upward.
1) Louver position in cooling operation
∗
1 When the indoor humidity is high (Hu sensor valve)
≥
70%), the compressor speed is 23 rps or more and the
position of the louver is less than 29°, the louver moves to 29° to prevent the air discharge from dew drop. And the
louver can’t move to less than 29°.
When the indoor humidity becomes low or the compressor speed becomes less than 23 rps, the louver returns to
the storage position.

2) Air
direction
adjustment
• The louver position can be arbitrarily set up by pushing [FIX] button.
3) Swing

2) Each time you push the SWING button, you can change the swing mode.
(Vertical swing

Vertical and Horizontal swing ® Stop swinging)
• Swing operation is performed in width 35° with the stop position as the centre.
• If the stop position exceeds either upper or lower limit position, swing operation is performed in width 35° from
the limit which the stop position exceeded.
