2. Manual vertical airflow direction can be set using remote control. The angels of the vane are as stated above.  When the air 
conditioner is stopped using remote control, the vane will shift to close position. 
* Above angle data is for reference only. 

The horizontal airflow direction louvers can be adjusted manually by hand. 

● To provide quiet operation comparing to normal operation. The Quiet operation can be active or stop by pressing 

QUIET/POWERFUL button on remote control.  

● Once Quiet mode is active, the unit will continuously operate in QUIET Mode until cancel the mode by pressing  

QUIET/POWERFUL button on remote control. 

● To cooling or heating the room faster comparing to normal operation. The POWERFUL operation can be active or 

stop by pressing QUIET/POWERFUL button on remote control.  

● When powerful operation is active, the unit will continuously operate in POWERFUL mode until cancel the mode 

by pressing  QUIET/POWERFUL button on remote control. Operation details are as the fig. below.

When the power supply is cut off during the operation of air conditioner, the compressor will re-operate within three to 
four minutes after power supply resumes.

Note: 

●    If POWER LED blinks, the possible operation of the unit is operation mode judgment, or ON timer 

sampling. 

●  If Timer LED blinks, there is an abnormal operation occurs. 

 

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 for ON Timer or ON-OFF Timer setting, 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 
mode. From the above judgment, the decided operation will start operate earlier than the set time as shown below.

● The Compressor will not turn on within 3 minutes from the moment operation stops, although the unit is turned on 

again by pressing OFF/ON button at remote control within this period. 

● This control is not applicable if the power supply is cut off and on again. 
● This phenomenon is to balance the pressure inside the refrigerant cycle.

 

● Once the air conditioner is turned on, the compressor will not stop within 30 seconds in a normal operation 

although the intake air temperature has reached the thermo-off temperature. However, force stop by pressing the 
OFF/ON button at the remote control is permitted or the Auto OFF/ON button at indoor unit. 

●  The reason for the compressor to force operation for minimum 30 seconds is to allow the refrigerant oil run in a 

full cycle and return back to the outdoor unit. 

1.  If the outdoor unit total running current is detected exceeding I

1

(A), the frequency instructed for compressor 

operation will be decreased. 

2.  If the running current does not exceed I

1

(A) for 5 seconds, the frequency instructed will be increased.

1.  DC Peak Current Control 

●  When electric current to IPM exceeds set value of DC17.3 1A, the compressor will stop. It will restart after 

three minutes. 

●  If the set value is exceeded again within 30 seconds, the operation will restart after one minute. 
●  If this condition repeats continuously for seven times, all indoor and outdoor relays will be cut off. 
●  Error code [F99] will be displayed. 

2.    Overheating protection control 

When the IPM temperature rises to 90 ℃ , compressor will stop immediately. 
Compressor restarts after three minutes if the temperature decreases to 97℃ 

Instructed frequency for compressor operation will be regulated compressor discharge temperature. The change of 
frequency is as below.

1. When the conditions listed in the table occur, the compressor stops and restarts after three minutes. 
2.  If this continuously occurs for twice within 20 minutes, all indoor and outdoor relays will be cut off. 
3. This control is not applicable for deice operation.

a. Control start conditions 

• For 5 minutes, the compressor continuously operates and outdoor total current is between 0.65A and 1.65A. 
• During Cooling and Soft Dry operations: 

Indoor suction temperature - indoor piping temperature is below 4℃. 
Indoor temperature and outdoor temperature is 30±5℃. 
Remote Control setting 16℃ and Hi Fan Speed. 

• During Heating operations: 

Indoor piping temperature - indoor suction is under 5℃. 
Indoor temperature and outdoor temperature is 20 ± 2℃. 
Remote control setting 30℃ and Hi Fan Speed. 

b. Control contents 

• Compressor stops (and restart after 3 minutes) 
• If the conditions above happen 2 times within 20 minutes, the unit will: 
- Stop operation 
- Timer LED blinks and “F91” indicated 

• The compressor operating frequency is regulated in accordance to the outdoor air temperature as shown in the 

diagram below. 

• This control will begin 1 minute after the compressor starts. 
• Compressor frequency will adjust base on outdoor air temperature.
