8 Operation Details
8.1.Cooling Mode Operation
Cooling in operation according to Remote Control setting.
Time Delay Safety Control (3 minutes)
• When the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.
• When the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3 minutes.
7 minutes Time Save Control
•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.
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.
Compressor Reverse Rotation Protection Control
•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 a instantaneous power failure.
Anti-Dew Formation Control
•Purpose is to prevent dew formation on indoor unit air discharge area.
•When the following conditions occur for 30 minutes continuously, anti-dew formation is controlled by indoor fan speed shift to low (Changed to Lo+):
−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.
•This control is cancelled immediately when above condition is changed.

Automatic Fan Speed Mode
When Automatic Fan Speed is selected at Remote Control during cooling operation.
•Fan speed rotates in the range of Hi to Me.
•Deodorizing Control.

8.2.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 at SLo speed.
•Once room temperature reaches below Soft Dry OFF temperature. Indoor Fan, Compressor and Outdoor Fan stop for 6 minutes.
Time Delay Safety Control
• Once the compressor stops, it will not start for 3 minutes during Cooling operation.
Anti-Freezing Control
•Same as Anti-Freezing Control for Cooling Mode operation. (For Soft Dry region, 6 minutes waiting is valid during compressor stops.)
Compressor Reverse Rotation Protection Control
•Same as Compressor Reverse Rotation Protection Control for Cooling Mode Operation. (For Soft Dry region, 6 minutes waiting is valid during compressor stops.)
Anti-Dew Formation Control
• Same as Anti-Dew Formation Control for Cooling Mode operation.
Automatic Fan Speed Mode
When Automatic Fan Speed is selected at Remote Control during Soft Dry operation.
•Fan speed off and on at SLo speed.
•Deodorizing Control.

8.3.Heating Mode Operation
• Heating in operation according to Remote Control setting.
Time Delay Safety Control
•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.
Overload Protection Control
(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 Tb or 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 Control
• 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.
Hot Start Control
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
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.
Anti Cold Draft Control

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 or 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.

8.4.Automatic Mode Operation
1.When the Automatic Mode Operation is selected, the indoor fan operates at SLo fan speed for 25 seconds to sense intake air temperature and determine the 1st operation mode. If indoor intake air temperature is less than 16°C, Heating mode will immediate operate.
2.Operation mode will be determine again after 1 hour of operation, if the room temperature reaches to set temperature and compressor off time is over 7 minutes 30 seconds continuously.
The present operation mode will be continued, if the room temperature does not reach to set temperature (Compressor keeps running) eventhough after 1 hour from automatic operation mode started.
