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 adjust 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 conditio n according to internal setting temperature and intake air temperature.
8.1.1. Internal Setting Temperature
Once the operation starts, remote controller setting temperature will be taken as base value for temperature shifting processes.
These shifting processes are depend ing 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 supplie d to the unit.

8.1.2. Frequency Instruction for Compressor Operation
Operation of compressor is based on instructed frequency, continuously from indoor unit´s microcomputer after performing
temperature sampling and judgment.
There are total 30 differen t frequency values, which listed as Table on Frequency Number, to be instructed based on the
temperature judgment

For normal start of operation, including Thermo-OFF, Deice-Resuming, and remote controller ON-OFF starts, the compressor
starts to operate at frequency no. 8, values of 30Hz and 32Hz for E9CKP and E12CKP respectively, for 60 seconds.
The frequency to be judged and instructed, however, starts to judge once the air conditioner operated and the judgment will
continue every 30 seconds until it is stopped by all kinds of compressor off conditions. This judgment is based on the internal
temperature sampling that involving internal setting temperature and intake air temperature.
From the internal sampling, the temperature differen t (intake air temperature - internal setting temperature) will be used to judge
the Zone on which the frequency to be instructed for the initial operation of compressor (refer to Table on Initial Frequency Zone).

After the initial operation, the instructed frequency will change or shift from initial frequency according to the judgment on
temperature differen t from sampling (refer to the Table on Shifting Frequency Zone).

8.1.7. Airflow Direction
1. There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by vertical vanes).
2. Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger temperature
and intake air temperature) and manual (angles of direction can be adjusted using remote controller).

1. Automatic vertical airflow direction can be set using remote controller; 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 controller, the vane will shift to close position.
2. Manual vertical airflow direction can be set using remote controller; 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 controller, the vane will shift
to close position.
Horizontal Airflow
1. Automatic horizontal airflow direction can be set using remote controller; 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.

8.1.8. Automatic Mode Operation
This mode can be set using remote controller and the operation is decided by remote controller 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 20 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 controller 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 controller setting is judged and performed, based
on the above operation mode chart, every 30 minutes. Heating mode operation will be performed, however, if deice operation is
detected.
Remote Controller 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 controller 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.
8.2. Protection Control Features
8.2.1. Delay ON Timer Control
This control is applica ble to all kinds of operation mode.
Delay ON timer can be set using remote controller, the unit with timer set will start operate earlier than the setting time. This is to
provide a comfortable environment when reaching the set ON time.
Seventy minutes before the set time, indoor (at fan speed of Lo-) and outdoor fan motor start operate for 20 seconds to determine
the indoor intake air temperature and outdoor air temperature in order to judge the operation mode.
From the above judgment, the decided operation will start operate earlier than the set time as shown below.
8.2.2. OFF Timer Control
This control is applica ble to all kinds of operation mode.
OFF timer can be set using remote controller, the unit with timer set will stop operate at set time.
