8 Operation Details
8.1.Basic Funtion
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.

CompHz = Freq. A × Freq. H + Freq. C
Example Calculation:

When Intake Air Temperature - Internal setting Temperature: 1.5°C
CompHz = Freq. A × Freq. H + Freq. C
=1.9 × 20 + 1.0
=39 Hz (It cuts down less than a decimal point)

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-XE9DKE CU-XE9DKE / CS-XE12DKE CU-XE12DKE
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.

8.1.10.2. Quiet operation (Heating)
A. Purpose
To provide quiet heating operation compare to normal operation.
B.Control condition
a. Quiet operation start condition
•When “quiet” button at remote control is pressed. Quiet LED illuminates.
b.Quiet operation stop condition
1.When one of the following conditions is satisfied, quiet operation stops:
a.Quiet button is pressed again.
b.Stop by OFF/ON switch.
c.Timer “off” activates.
d.When change mode to fan only mode.
2.When quiet operation is stopped, operation is shifted to normal operation with previous setting.
3.When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.
4.When operation mode is changed, quiet operation is shifted to quiet operation of the new mode, except fan only mode.
5.During quiet operation, if timer “on” activates, quiet operation maintains.
6.After off, when on back, quiet operation is not memorised.
C.Control contents
a. Fan Speed manual
1.Fan speed is changed from normal setting to quiet setting of respective fan speed. This is to reduce sound of Hi, Me, Lo for 3dB.
2.Fan speed for quiet operation is -100 rpm from setting fan speed.
3.Fan Speed Auto
•If FM 
Lo
-100 rpm reduce from normal Heating Auto Fan Speed
•If FM 
Lo maintain RPM
Indoor FM RPM depends on pipe temp sensor of indoor heat exchanger.

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-XE9DKE CU-XE9DKE / CS-XE12DKE CU-XE12DKE
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
a.Ionizer Only Operation.
1.When an air-conditioner unit is at “OFF” condition (standby) and an ION operation button at remote control is pressed. 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-XE9DKE CU-XE9DKE / CS-XE12DKE CU-XE12DKE
control is pressed. Ionizer on & ION LED illuminates. (3 → 4)
Power LED also illuminates.
2.Ionising Operation Stop Condition
When one of the following condition is satisfied, ION operation stops.
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
Refer to case study in next page for detail.
