(3) Positioning
The vane is once pressed to the vane stopper below to confirm the standard position and then set to the desired angle.
The positioning is decided as follows.
(a) When the OPERATE/STOP button is pressed. (POWER ON/OFF)
(b) When the vane control is changed from AUTO to MANUAL.
(c) When the SWING is finished.
(d) When the test run starts.
(e) When the power supply turns ON.
(4) VANE AUTO (
) mode
In VANE AUTO mode, the microprocessor automatically determines the vane angle and operation to make the optimum
room-temperature distribution.
(5) Dew prevention
During COOL or DRY operation at vane Angle 4 or 5 when the compressor cumulative operation time exceeds 1 hour, the
vane angle automatically changes to Angle 1 for dew prevention.
(6) SWING MODE (
)
By pressing the SWING button (
) vane swings vertically. The remote controller displays “
”. SWING mode is cancelled
when the SWING button or VANE CONTROL button (
) is pressed or the operation stops or changes to other mode.
(7) Cold air prevention in HEAT operation
When either of the following conditions occurs in HEAT operation, the horizontal vane angle changes to Angle 1 automati-
cally to prevent cold air blowing on users.
①
Compressor is not operating.
➁
Defrosting is performed.
➂
Indoor coil thermistor RT12 reads 24
:
or below.
➃
Indoor coil thermistor RT12 temperature is raising from 24°C or below, but it does not exceed 28
:
.
①
In COOL and DRY operation
➁
In HEAT operation
Vane angle is fixed to Angle 1.
Vane angle is fixed to Angle 4.
8-7. SLEEP MODE (
)
• When the SLEEP button (
) is pressed, the indoor fan speed drops and the air flow sound from the
indoor unit is decreased.
• The indications of the remote controller are “
” and “
”.
• When the FAN SPEED CONTROL button ( ) is pressed during the SLEEP mode, the SLEEP
mode is released.
