8.1. BASIC FUNCTION
8 Operation Details
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes,
automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the
microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature
shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that
judging the condition according to internal setting temperature and intake air temperature.
8.1.1. Internal Setting Temperature
Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes.
These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value
will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.

8.1.3. Cooling Operation
8.1.3.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -1.5°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF
point +0.5°C.

8.1.4. Soft Dry Operation
8.1.4.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -2.5°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF
point.
8.1.5. Heating Operation
8.1.5.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting > +1.5°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature < Compressor OFF
point -0.5°C.
8.1.6. Automatic Operation
This mode can be set using remote control and the operation is decided by remote control setting temperature, indoor intake air
temperature and outdoor air temperature.
During operation mode judgment, indoor fan motor (with speed of Lo-) and outdoor fan motor are running for 30 seconds to detect
the indoor intake and outdoor air temperature. The operation mode is decided based on below chart.
18

Values of T1, T2, and T3 depend on remote control setting temperature, as shown in below table. After the adjustment of T1, T2
and T3 values, the operation mode for that particular environment and remote control setting is judged and performed, based on
the above operation mode chart, every 30 minutes.
Remote Control Setting Temperature (°C) T1 T2 T3
16 ~ 18 +10 +8 -5
19 ~ 22 +8 +7 -7
23 ~ 26 +7 +6 -7
27 ~ 30 +6 +5 -8
There is a temperature shifting on T1, T2, and T3 if the operation mode judged is changed from Cooling/Soft Dry to Heating or vice
verse.
Operation Mode change from Temperature shifts (°C)
Cooling/Soft Dry →Heating -2
Heating →Cooling/Soft Dry +2
Example of operation mode chart adjustment:
From the above table, if remote control setting temperature = 25,
T1 = 25 + 7 = 32; T2 = 25 + 6 = 31; T3 = 25 - 7 = 18
The operation mode chart for this example is as shown in below figure and the operation mode to be performed will depend on
indoor intake air temperature and outdoor air temperature at the time when the judgment is made.
