Operation Details
1) Cooling Mode Operation
Cooling in operation according to Remote Control setting.
• When the compressor is stopped by Power Switch, Remote Control or there is a power failure, it restarts after 3
minutes when the Power Switch, Remote Control is turned ON or the power supply is resumed.
• When the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3
minutes.
• The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is below the
compressor ON temperature.
Time Delay Safety Control (3 minutes)
7 minutes Time Saved Control
Anti-Freezing Control
• If the temperature of the indoor heat exchanger
falls continously below 2°C for 4 minutes, the
compressor turns off to protect the indoor heat
exchanger from freezing. The fan speed setting
remains the same.
• Compressor recommences when the indoor heat
exchanger temperature rises to 10°C (Recovery).
*3 minutes waiting of Time Delay Safety Control
is valid for Cooling Operation.

Operation Details
2) Soft Dry Mode Operation
• The unit starts cooling operation until the room temperature reaches the setting temperature set on the Remote
Control, and then Soft Dry operation will start.
• During Soft Dry operation, the Indoor Fan will operate and stop at 4-second intervals at low speed.
• The operation will be switched on and off for up to 10 minutes “ON” and 6 minutes “OFF”. Once Soft Dry opera-
tion is turned off, it stops for 6 minutes.
• Once the compressor stops, it will not start for 3 minutes during Cooling operation.
• Same as Anti-Freezing Control for Cooling Mode operation. (For Soft Dry region, 6 minutes waiting is valid during
compressor stops.)
When Automatic Fan Speed is selected at Remote Control during Soft Dry Operation.
• Fan speed rotates at SLo and Lo speed.
• Deodorizing Control.
*SLo: Indoor Fan rotates at 4-second intervals at low speed.

4) Automatic Mode Operation
Standard for Determining Operation Mode
(a) Indoor fan operates at Lo fan speed for 20 seconds.
(b) After judging indoor air temperature, the operation mode is determined and operation continued at the mode
determined.
(c) After the operation mode has been determined, the mode does not change. However, Soft Dry mode operation
includes Cooling mode operation.
(d) Room temperature adjustment.
The following are added to the setting temperature specified as above.
(e) If the value for R32 is changed to 47K (Normal 10K), the mode judging temperature and standard setting
temperature is increased by 2°C.

Operation Details
5) Sleep Mode Auto Operation
Cooling or Soft Dry Operation
6) Auto Restart Control
• If there is a power failure, operation will be automatically restarted when the power is resumed.
It will start with previous operation mode and airflow direction.
(Time Delay Safety Control is valid)
• Auto Restart Control is not available when Timer or Sleep Mode is set.
• This control can be omitted by cutting the jumper wire J2. (Refer Circuit Diagram)
Whenyoupressthe SLEEP Mode, thefollowingmove-
ment will start to avoid overcooling.
• When the room temperature reaches the setting
temperature or after 1 hour of operation, sleep shift
operation starts and the airflow volume will automati-
cally change to low.
• The setting temperature will be risen by 0.5°C at the
start of operation and by 0.5°C one hour later.
• The operation will stop after 8hours.
7) Indoor Fan Speed Control
• Auto Fan Speed Control
When set to Auto Fan Speed, the fan speed is adjusted between maximum and minimum setting as shown in the
table.
• Manual Fan Speed Control
Basic fan speed adjustment (3 settings, from Lo to Hi) can be carried out by using the Fan Speed selection
button.

*1 There is no swinging while indoor fan is stopped during Cooling and Soft Dry operation.
*2 In Air Circulation operation, when the intake air temperature reaches set temperature, the airflow direction is
changed from upper limit to lower limit. When the intake air temperature falls to 2°C lower than set temperature,
the airflow direction is changed from lower limit to upper limit.
•When the airflow direction set button is pressed,
the automatic airflow is released and the airflow
