7. Louver control
1) Louver
position
Operation flow and applicable data, etc.
This function controls the air direction of the indoor unit.
Description
2) Louver position during heating and fan operation
• 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)
• When the power supply turned on and operation of the air conditioner stopped, the louver is fully
opened once and then becomes full close status.
2) Cold draft
preventive
control
3) During swing operation (All operation modes)
Pushing [FIX] button of the remote
controller during cooling or drying
operation moves the louver. The
louver operates in the range
between lower limit angle (36°) and
cooling upper limit angle (52°).
(Except swinging time)
Pushing [FIX] button of the remote
controller during heating or fan
operation moves the louver. The
louver operates in the range
between lower limit angle (36°) and
upper limit angle (92°).
Pushing [SWING] button of the
remote controller during operation
of the air conditioner swings the
louver. The louver swings in the
range between lower limit angle
(36°) and upper limit angle (92°).
(Even during cooling or drying
operation) When pushing [SWING]
button during swinging operation,
swinging operation stops.
1) Louver position during cooling or drying operation (Except swinging time)
• To prevent the cold draft during heating operation, fix lower limit angle of the louver to 36° if
temperature of the indoor heat exchanger is low. This control is not operated during cooling, drying
or fan operation.
1) At increase of Tc sensor temp.
The lower limit angle of the louver is fixed to 36° until Tc sensor temp exceeds Z°C. In this case,
the louver does not operate even if [FIX] or [SWING] button is pushed. When Tc sensor temp
exceeded Z°C, the louver moves to the HEAT memory position.
2) At decrease of Tc sensor temp.
The louver is at the HEAT memory position until Tc sensor temp exceeds Z–2°C.
Tc sensor temp exceeded Z–2°C, the louver moves to the lower limit angle (36°).
