will move to D clockwise; under other modes, the up-and-down air
the machine, then the wind blade will swing between
L
and D. The air
Location D, Location L to Location D, stop at any location between L-D (the included angle between L~D is the same).
fectual only on condition that setting the swinging order and the inner

If swing function is set when turning on the unit, the vertical louver will swing between L
and D.
Vertical louver has 7 swing statuses:
◆
Stay at position L: control by remote controller:
◆
Stay at position A: control by remote controller:
◆
Stay at position B: control by remote controller:
◆
Stay at position C: control by remote controller:
◆
Stay at position D: control by remote controller:

◆
Stop at any position between
L
and D (angles between
L and D are equiangular), control by remote controller: OFF
③
When turning off the unit, vertical louver will close at position O.
④
Swing action is valid only when swing command has been set and the IDU fan motor is operating.

①
Operation pattern and mode pattern display
All the display patterns will display for a time when the power on, the operation indication pattern will display in red under standby status.
When the machine is start by remote control, the indication pattern will light and display the current operation mode (the mode light in
-
cludes: Cooling, heating and dehumidify). If you close the light key
, all the display patterns will close.
②
Double-8 display
According to the dif
ferent setting of remote control, the nixie light may display the current temperature (the temperature scope is from 16°C
(60.8°F
)
to 30°C
(86
°F
)) and indoor ambient temperature.
The set temperature displayed in auto cooling and fan mode is 25°C(77°F
) and
the set temperature displayed in auto heat
ing mode is 20°C
(68
°F
). Under heating mode, nixie tube
