Cooling in operation according to Remote Control setting.
Time Delay Safety Control (3 minutes)
7 minutes Time Save Control
Anti-Freezing Control
• • •
• If the temperature of the indoor heat exchanger falls
continuously below 2°C for 4 minutes or more, the
compressor turns off to protect the indoor heat exchanger
from freezing. The fan speed setting remains the same.
• • •
• Compressor will restart again when the indoor heat
exchanger temperature rises to 10°C (Recovery).
3 minutes waiting of Time Delay Safety Control is valid for
Cooling Operation.
8 Operation Details
8.1. 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 at the remote
control.
8.2. Cooling Mode Operation
• • •
• If the operation is stopped by the remote control, the compressor will not turn on within 3 minutes from the moment operation
stop, although the unit is turn on again within the period.
• • •
• 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 between the compressor
ON temperature and OFF temperature.

Compressor Reverse Rotation Protection Control
Anti-Dew Formation Control
Automatic Fan Speed Mode
• • •
• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and
indoor heat exchanger is 2.5°C or less for 2 minutes, compressor will stop and restart automatically.
(Time Delay Safety Control is valid)
▲T = Intake air temperature - Indoor heat exchanger temperature
This is to protect reverse rotation of the compressor when there is an instantaneous power failure.
• • •
• Purpose is to prevent dew formation on indoor unit air discharge area.
• • •
• When room temperature is constant (±1°C) the following conditions occur for 30 minutes continuously, anti-dew formation will
activate:
− − −
− Indoor intake air temperature is more than 24°C and less than 30°C.
− − −
− Remote Control setting temperature is less than 25°C.
− − −
− Compressor is on.
− − −
− Cooling operation mode.
− − −
− Indoor Fan motor operate at Low fan speed or QLo.
• • •
• This control is cancelled immediately when above condition is changed.
• • •
• Anti-Dew formation is control by:
1. Lo fan speed
Lo fan is changed to Lo+ fan
When Automatic Fan Speed is selected at Remote Control during cooling operation.
• • •
• Fan speed rotates in the range of Hi to Me.
• • •
• Deodorizing Control.

8.3. 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 at Lo- speed.
• • •
• Once room temperature reaches below Soft Dry OFF temperature. Indoor Fan, Compressor and Outdoor Fan stop 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.)
• • •
• Same as Compressor Reverse Rotation Protection Control for Cooling Mode Operation. (For Soft Dry region, 6 minutes waiting
is valid during compressor stops.)
• • •
• Same as Anti-Dew Formation Control for Cooling Mode operation.
When Automatic Fan Speed is selected at Remote Control during Soft Dry operation.
• • •
• Fan speed off and on at Lo- speed.
• • •
• Deodorizing Control.

8.4. Heating Mode Operation
• • •
• Heating 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 heating operation, the compressor stops and it will not start for 4 minutes.
(a) Outdoor Fan Control
• • •
• If the temperature of the Outdoor Heat Exchanger less than -3°C, Outdoor Fan is ON. The Outdoor Fan stop, when Outdoor
Heat Exchanger temperature is Tbor more according to Outdoor Air Temperature region as table below:
The Outdoor Fan restarts when the indoor heat exchanger temperature falls to 49°C.
During starting of Heating mode and after deice, Outdoor Fan ON for 90 sec. (Hi).
(b) Compressor High Pressure Control
• • •
• If the indoor heat exchanger becomes 68°C or more, the compressor will stop and restart automatically.
(Time Delay Safety Control - 4 minutes waiting).
• • •
• 4-way valve ON during Heating operation, except deicing operation.
• • •
• When the unit is switched to “OFF” during Heating operation, 4-way valve stays at Heating position for 5 minutes.
When Heating operation starts, Indoor Fan will not start until the indoor heat exchanger reaches 30°C as diagram shown.
Hot Start is completed when indoor heat exchanger reaches 42°C.
Maximum Hot start duration = 4 minutes. After 4 minutes,
Hot start operation will be shifted to normal Heating operation.

Automatic Fan Speed Mode
Anti Cold Draft Control
Compressor Reverse Rotation Protection Control
When Automatic Fan Speed is selected at Remote Control during heating operation.
• • •
• Fan speed rotates in the range of Me →SLo according to the heat exchanger temperature.
• • •
• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between indoor heat
exchanger and intake air is 5°C or less for 2 minutes, compressor will stop and restart automatically.
(Time Delay Safety Control is valid)
▲T = Indoor heat exchanger temperature - Intake air temperature
This is to protect reverse rotation of the compressor when there is an instantaneous power failure.

Heating Operation Time Diagram
Deicing Control
Deice starts to prevent frosting at outdoor heat exchanger.
• • •
• Normal Deicing
Deice operation detection commences in Heating operation starts or 60 minutes after previous deice operation. If the
outdoor piping temperature drops to -4°C for 50 sec. continuously during compressor is in operation, deice will start.
(There is no detection during Outdoor Fan stops.)
• • •
• Overload Deicing
During heating operation, if the outdoor Fan OFF duration (due to overload control) is accumulated up to 60 minutes and
after compressor starts for 1 minutes, deicing starts.
• • •
• Deicing ends when
(a) 12 minutes after deicing operation starts;
(b) The outdoor piping temperature rises to about 12°C.
• • •
• After deicing operation, compressor stops for 30 seconds and 4-way valve stays at cooling position for 10 seconds.
