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 to air heat pump oper-
ation 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 26qC 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 26qC 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 to air heat pump shows
the remaining minutes: 40 o 39 o 38 ... 3 o 2 o 1)
1.21. Plasmacluster Ion function
The Plasmacluster lon generator inside the air conditioner will release
positive and negative plasmacluster ions into the room. Approximately
the same numbers of positive and negative ions released into the air
will reduce some airborne mold.
During operation, press the PLASMACLUSTER button.
• The remote control will display “ “.
• The blue PLASMACLUSTER lamp on the unit will light up.
TO CANCEL
Press the PLASMACLUSTER button again.
• The PLASMACLUSTER lamp on the unit will turn off.
NOTE: • Use of the PLASMACLUSTER operation will be memo-
rized, and it will be activated the next time you turn on the
air conditioner.
• To turn off the PLASMACLUSTER lamp, press the DIS-
PLAY button.
• To perform the PLASMACLUSTER operation in FAN only
mode, press the PLASMACLUSTER button while the unit
is not operating. The mode symbol of the remote control
will go off and the fan speed can not be set to AUTO.
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 -10qC 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 21qC DB., depending on conditions.
1.24. 10qC OPERATION
Heating operation with 10qC 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 10qC button.
• The remote control will display 10qC.
TO CANCEL
Press the 10qC button again.
• 10qC operation will also be cancelled when the operation mode is
changed, or when the unit is turned off.
NOTE:
• 10qC 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.
1.25.1 Operating mode (Cool, Heat, Dry)
