1.18. Dehumidifying operation control
If the room temperature is 26°C or higher when dehumidifying
operation starts, the dehumidifying operation provides a low
cooling effect in accordance with the room temperature setting
automatically determined 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
operation starts, the dehumidifying operation minimizes the
lowering of the room temperature.
1.19. Self Clean operation
Heating or Fan operation and Cluster operation are performed
simultaneously.
Whether start Heating or Fan operation is determined by the
outside air temperature at 3 minutes after the start of self
cleaning.
The operation stops after 40 minutes. (The air to air heat pump
shows the remaining minutes: 40 → 39 → 38 ... 3 → 2 → 1)
1.20. 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
memorized, and it will be activated the next time you turn on
the air conditioner.
• To turn off the PLASMACLUSTER lamp, press the
DISPLAY 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.
1.21. 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.
1.22. 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°C.
TO CANCEL
Press the 10°C button again.
• 10°C operation will also be cancelled when the operation
mode is changed, or when the unit is turned off.
NOTE:
• 10°C operation will not be available with heating operation
automatically selected by AUTO mode.
1.23. 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.
1.23.1 Operating mode (Cool, Heat, Dry)
• Temperature adjustment (within 2°C range)
automatic operation
• Temperature setting
• Fan setting
• Air flow direction
• Power ON/OFF
• Automatic operation mode setting
• Swing louvre
• Plasmacluster mode
1.23.2 Setting not memorized
• Timer setting
• Full power setting
• Self clean
1.23.3 Disabling auto restart function
By removing (cutting) jumper 8 (JP8) on the printed circuit board
(PCB), the auto restart function can be disabled.
