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 supplie d to the unit.

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
CS-XE9CKE CU-XE9CKE / CS-XE12CKE CU-XE12CKE
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.

8.1.9. 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 control).

8.1.11. Delay ON Timer Control
Delay ON timer can be set using remote control, 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 30 seconds to determine
the indoor intake air temperature and outdoor air temperature in order to judge the operation starting time.
From the above judgment, the decided operation will start operate earlier than the set time as shown below.
8.1.12. Delay OFF Timer Control
Delay OFF timer can be set using remote control, the unit with timer set will stop operate at set time.
8.1.13. Auto Restart Control
1. When the power supply is cut off during the operation of air conditioner, the compressor will re-operate within three to four
minutes (there are 10 patterns between 2 minutes 58 seconds and 3 minutes 52 seconds to be selected randomly) after power
supply resumes.
2. This type of control is not applicable during ON/OFF Timer setting.
8.1.14. Auto Operation Switch
1. When the switch is pressed between 0 to 5 seconds, Auto Mode operation starts to function.
2. When the switch is pressed between 5 to 8 seconds, the unit is forced to operate in Cooling Mode.
3. When the switch is pressed between 8 to 11 seconds, the unit is forced to operate in Heating Mode.
27
CS-XE9CKE CU-XE9CKE / CS-XE12CKE CU-XE12CKE
4. When the switch is pressed between 11 to 16 seconds and together with the signal from remote control, the unit can be
changed to different controlling setting (A-B mode) or to testify oxygen operation.
5. When the switch is pressed between 16 to 21 seconds, either “H14” error detection selection mode or the remote control signal
receiving sound can be cancelled or turned on.
8.1.15. Indoor Power Relay Control
Power relay will turn on during operation or in progress of stopping operation. Although operation stops, the power relay continues
on for three minutes.
However, during an instantaneous power failure (< 0.5s), power relay will turn off. Then, it will turn on 2 minutes after power recover
and the unit will operate as previous operation condition.
8.1.16. Ionizer Operation
Purpose
To provide fresh air effect to users by discharging minus ion to air.
Control Condition

Fan & ionizer on, ION LED illuminates, but power LED maintain off. (1 → 2)
However, fan speed can be adjusted later by customer during this operation.
Airflow direction (Horizontal Vane) control:
Follow vane direction control at cooling mode.
Horizontal vane can be changed by customer during ion only operation.
b. Operation Mode + Ionizer Operation.
1. Ionising Operation Start Condition
When an air conditioner unit is in “ON” condition (Heat, Cool, Dry, Fan, Auto mode) and an ION operation button at remote
28
CS-XE9CKE CU-XE9CKE / CS-XE12CKE CU-XE12CKE

a. Stopped by ON/OFF switch.
b. Timer OFF activates.
c. ION operation button is pressed again.
d. ION feedback signal shows error.
3. Ionizer operation status is not memorised by micon. After OFF, when operation is “ON” again, air conditioner operates
without ionizer operation.
c. Timer during ionizer operation
