1.18. Difference of operation in Auto and Manual modes

In the Auto mode, the temperature setting is automatically determined based on the outside air temperature. In addition, the air conditioner operation
differs from the operation in the Manual mode as explained below.

1.18.1 Difference relating to set temperature

1.19. Dehumidifying operation control

If the room temperature is 26

C or higher when dehumidifying opera-

tion starts, the dehumidifying operation provides a low cooling effect in
accordance with the room temperature setting automatically deter-
mined based on the outside air operation. (The setting value is the
same as the set temperature for cooling operation in the auto mode.)

If the room temperature is lower than 26

C when dehumidifying opera-

tion starts, the dehumidifying operation minimizes the lowering of the
room temperature.

1.20. Self Clean operation

Heating or Fan operation and Cluster operation are performed simulta-
neously.

The judgment of whether Heating or Fan operation is used is based on
the outside air temperature at 3 minutes after the start of internal
cleaning.

The operation stops after 40 minutes. (The air conditioner shows the
remaining minutes: 40

1.21. Plasmacluster Ion function

Operating the Plasmacluster Ion button while the air conditioner is in
operation or in non-operation allows the switching of the operation
mode in the following sequence: “Air Clean operation”

→

“Stop”.

•

“Self Clean operation” generates about equal amounts of (+)ions
and (-)ions from the cluster unit to provide clean air.

If the Plasmacluster Ion generation function is operated together with
the air conditioner operation, the indoor unit fan speed and louver
direction are in accordance with the air conditioner settings.

If the Plasmacluster Ion generation function is used without operating
the air conditioning function, the indoor unit fan operates at a very low
speed and the upper louver is angled upward and the lower louver
remains horizontal. (The airflow volume and direction can be changed
by using the remote control.)

1.22. Hot keep

If the room temperature is in the Hot keep zone during heating, the
compressor is turned off to prevent overheating.

1.23. Winter cool

Cooling operation is available during the winter season by the built in
winter cool function.

Lower limit of outdoor temperature range is -10

C DB.

When the outside air temperature is low, the outdoor unit fan operates
at slower speed.

NOTE: Built-in protect device may work when outdoor temperature

falls below 21

C DB., depending on conditions.

1.24. 10

C OPERATION

Heating operation with 10

C set temperature will be performed.

1) Press the MODE button of Remote controller and select HEAT

mode.

2) Press the ON / OFF button to start HEAT operation.

3) Press the 10

C button.

•

The remote control will display 10

TO CANCEL

Press the 10

C button again.

•

C operation will also be cancelled when the operation mode is

changed, or when the unit is turned off.

NOTE:

•

C operation will not be available with heating operation auto-

matically selected by AUTO mode.

1.25. Auto restart

When power failure occures, after power is recovered, the unit will
automatically restart in the same setting which were active before the
power failure.
