NOTE: When 2 or more indoor units are operated with multi outdoor unit, even if any indoor unit turns thermostat off,
this control doesn’t work in the indoor unit.
(8) Cold air prevention in HEAT operation.
When any of the following conditions occurs in HEAT operation, the vane angle changes to Horizontal position 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 39
:
.
⑤
For about 3 minutes after compressor starts.
The air conditioner starts heat-
ing operation approx. 3 minutes
after the vane has moved to the
horizontal position.
•
Sometimes the area
around your feet may not
warm. To warn the area
around the feet, set the
horizontal vane to
(AUTO) or the downward-
blowing position.
•
When VANE CONTROL
button is pressed again,
the vane returns to the
previously-set position
and the air conditioner
starts the heating operation
in approx. 3minutes.
To change the air
flow direction
When to use this function?
Use this function if you don’t
want the air from the indoor
unit to blow directly onto your
body.
• Depending on the shape of
the room,the air may blow
directly onto your body.
• Press VANE CONTROL
button again to return the
vane to the previously-set
position.
The air conditioner starts the
cooling or drying operation
approx. 3 minutes after the
vane has moved to the hori-
zontal position.
•
Pressing and holding
VANE CONTROL
button for 2 seconds
or more causes
the horizontal vane
to reverse and
move to horizontal
position.
COOL/DRY
HEAT
NOTE:
• If you make the air flow not to blow directly onto your body by pressing VANE CONTROL button,
the compressor stops for 3 minutes even during the operation of the air conditioner.
• The air conditioner operates with decreased air flow until the compressor turns on again.
(9) To change the air flow direction not to blow directly onto your body.

When VANE CONTROL
button is pressed again,
the vane returns to the
previously-set position
and the air conditioner
starts the cooling or
drying operation in
approx. 3minutes.
<SWING operation>
In swing operation of ECONO COOL operation mode, the initial air flow direction is adjusted to “Horizontal”.
According to the temperature of indoor coil thermistor RT12 at starting of this operation, next downward blow time is
decided. Then when the downward blow has been finished, next horizontal blow time is decided.
For initial 10 minutes the swing operation is performed in table G~H for quick cooling.
Also, after 10 minutes when the difference of set temperature and room temperature is more than 2
:
, the swing oper-
ation is performed in table D~H for more cooling.
The air conditioner repeats the swing operation in various cycle as follows.

(10) ECONO COOL (
) operation (ECONOmical operation)
When ECONO COOL button is pressed in COOL mode, set temperature is automatically set 2°C higher.
Also the horizontal vane swings in various cycle according to the temperature of indoor heat exchanger(RT12).
SWING operation makes you feel cooler than set temperature. So, even though the set temperature is higher, the air
conditioner can keep comfort. As a result, energy can be saved.
ECONO COOL operation is cancelled when ECONO COOL button is pressed once again or VANE CONTROL
button is pressed or change to other operation mode.
