Ŷ Light Control 
If set the light is on with remote control, the indicator lamp and dual-8 display the current setting status; if set the 
light is off with remote control, turn off the lamp immediately. If there is front panel button or remote control button 
operation when setting light off with remote control, the indicator lamp and dual-8 display current setting status, 
and turn off the light 5S later. Remote control light button does not controlled by failure display.   
Ŷ SWING Motor Control 
After the unit is energized, the swing (up and down) motor will make the guide louver circumvolve to position 0; 
close  the  outlet  port.  After  the  unit  is  on,  if  it  does  not  set  swing  function,  guide  louver  (up  and  down)  will 
circumvolve to position D. Setting swing function when the unit is on, the guide louver swings between L and D. 
There  are  7  swing  statuses  for  guide  louver:  position  L,  position  A,  position  B,  position  C,  position  D,  swing 
between position L and D, stop between any position L and D.   
When the unit is off, the guide louver will chose to position 0. The swing action is valid when setting swing order 
and indoor fan is running. 
Note: When the remote control setting is on position L to B, position A to C, position B to D, the guide louver swings 
between position L and D. The angle of energized reset swing off is: 80°; when the unit is off, add 5°to the current 
angle then close guide louver. The corresponding angle of position L to D is: 39°-48°-57°-66°-75°. 
 
Ŷ Protection Function 
Ɣ Anti-freeze Protection 
When the anti-freeze protection is inspected, the compressor stops, fan motor runs with setting fan speed. When 
the anti-freeze protection is canceled and reaches to the 3min time-delay, it runs with the original status. 
Temperature s e n s o r   f ailure ins pe c t i o n  
e)  Environment temperature sensor is open, short circuit: dual-8 displays F1, the cooling indicator lamp goes out 
3S and blinks 1 time, and it will light up 0.5S and go out 0.5S when it is blinking. 
f)  Indoor pipe temperature sensor is open, short circuit: dual-8 displays F2, the cooling indicator lamp goes out 
3S and blinks 2 times, and it will light up 0.5S and go out 0.5S when it is blinking. 
g)  Outdoor pipe temperature sensor is open, short circuit: dual-8 displays F4, the cooling indicator lamp goes out 
3S and blinks 2 times, and it will light up 0.5S and go out 0.5S when it is blinking. 
h)  The compressor or electric heating pipe stops when the temperature sensor failure and the unit is on, The fan 
motor will be deal regarding compressor or electric pipe reach to the temperature point and stops. 
ƽ Over current Protection 
If the system current is inspected too large for 3min continuously, the fan motor runs with setting conditions, other 
load  stops;  3min  later,  the  unit  runs  with  the  previously status; if over current protection occurs for 6 times 
continuously, display error  code  “E5”,  the  load  stops this time; if block the button except ON/OFF button,  it  will 
remote control the unit to off then on, or turn off with button, or re-energized; the time of over current protection will 
zero clearing with remote control, press to turn on or re-energized. 
ƽ Over-flow Protection 
If the over-flow is detected for 3S, it will enter into over-flow protection. Display error code H8, heating indicator 
lamp or over-flow indicator lamp goes out 3S and blinks 8 times.
