8 Operation Details
8.1.Basic Function
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.

Operating Frequency Calculation Formula:
CompHz = Freq. A × Freq. H + Freq. C
Example Calculation:
Model No.: E18DK
Operation Mode: Cooling
When Intake Air Temperature - Internal setting Temperature: 1.5°C
CompHz = Freq. A × Freq. H + Freq. C
=1.53 × 46 + 2.5
=72 Hz (It cuts down less than a decimal point)

When Freq. H is equal to 46 (Cooling), 39 (Heating) or above, the Comp. may run at the freq. higher than Fc or Fh up to max. freq. operation.
Best Amenity Control
Every 90s (Cooling), 120s (Heating) maintain same zone Freq. H + 1 until Fc (46), Fh (39).
8.1.3.Cooling Operation
8.1.3.1.Thermostat control
•Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -1.5°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.
21
CS-E15DKDW CU-E15DKD / CS-E18DKDW CU-E18DKD / CS-E21DKDS CU-E21DKD
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.

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.

1.Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the angles as stated above. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below. When the air conditioner is stopped using remote control, the vane will shift to close position.
2.Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above and the positions of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, the vane will shift to close position.
Horizontal Airflow
1.Automatic horizontal airflow direction can be set using remote control; the vane swings left and right within the angles as stated below. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below.
