8 Operation Details
8.1. Basic Operation
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes,
automatically adjust output power for maximum comfort always.
In order to achieve the suitable operation mode, the microcomputer maintains the set temperature by measuring the
temperature of environment and performing temperature shifting.
8.1.1. Temperature Shifting Flow
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.
16
CS-E15DD3EW CU-E15DBE / CS-E18DD3E W CU-E18DBE

8.1.2. Cooling Operation
8.1.2.1. 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.
8.1.3. Soft Dry Operation
8.1.3.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -2.0°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF
point.
8.1.4. Heating Operation
8.1.4.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature > +2.0°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature < Compressor OFF
point.
17
CS-E15DD3EW CU-E15DBE / CS-E18DD3E W CU-E18DBE

8.1.5. 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.
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 -3 -5
19 ~ 22 +8 -3 -7
23 ~ 26 +7 -3 -7
27 ~ 30 +6 -3 -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 - 3 = 22; 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.
