Ŷ DRY Mode 
Ɣ Working conditions and process of dry 
Under this mode, the unit will not display setting temperature and ambient temperature; the fan motor runs under low 
fan speed; the compressor, fan motor and kick motor continue to run. 
Ŷ FAN Mode 
Ɣ Under this mode, the unit will not display setting temperature and ambient temperature; the fan motor runs under 
setting fan speed; the compressor, fan motor and kick motor stop to run. 
Ɣ Under this mode, the centigrade temperature setting range is 16ć-30ć, the fahrenheit temperature setting range 
is 61-86. 
Ŷ AUTO Mode 
Ɣ Under AUTO mode, the standard cooling Tpreset=25ć(77), standard heating Tpreset=20ć(68) 
Ɣ It will goes to auto cooling mode when Tamb.>26ć(79); and goes to auto fan mode when Tamb.<20ć(68); 
20ć(68)Ta m b . 23ć(73), if  the previous running is  fan (including general  fan and auto fan),  it will keep the 
running  status  of  auto  fan  mode,  if the previous running is not fan,  it  will  goes  to  auto  dry  mode; 
26ć(79)Ta m b . 24ć(74),  it  goes  to  auto  dry  mode;  when  the  unit  is  first  energized, 
26ć(79)Ta m b . 20ć(68), it runs under dry mode. 
 
8.2.3 Other Functions 
Ŷ Buzzer 
When the controller is energized, receiving a  signal from remote controller or button, the buzzer will give out a 
beep. 
Ŷ Sleep 
a) Under cooling mode, after 1h of setting sleep process, Tpreset increases 2(1ć); 2h later, Tpreset increases 
4(2ć). After 2h, the setting temperature never increases, but the upper limit of increased setting temperature is 
86(30ć) 
b) Under heating mode, after 1h of setting sleep process, Tpreset decreases 2(1ć); 2h later, Tpreset decreases 
4(2ć). After 2h, the setting temperature never decreases, but the upper limit of decreased setting temperature is 
61(16ć) 
c) There is no sleep function under fan and dry mode. 
d) When set sleep function, shift mode will cancel sleep function. 
e) The setting temperature display is the same with remote controller; it is not influenced by the setting temperature 
increases/decreases. 
Ŷ Auto Fan 
a) Auto fan speed under cooling mode 
TambTpreset+4 (2 )                                    High fan;ć  
Tpreset<Tamb.< Tpreset+4 (2 )            Med fan;ć  
TambT preset       Low fan 
b) There is 3.5min delay for auto fan shift. 
Ŷ TIMER Function 
Ɣ General timer 
a) TIMER ON:  It can set timer  on when the  system is off,  the setting time  range  is 0.5h-24h, when  the time of 
setting timer on reaches, and the system runs with the previous setting mode. 
b) TIMER OFF: It can set timer on when the system is on, the setting time range is 0.5h-24h, when the time of 
setting timer off reaches, the system stop to work. 
Ɣ Clock timer 
a) TIMER ON: If set timer on when the system is running, it continues to run; if set timer on when the system is off, 
when the time of setting timer on reaches, and the system runs with the previous setting mode. 
b) TIMER OFF: If set timer off when the system is off, the system keeps the stand-by status when setting timer off; 
if set timer off when the system is on, when the time of timer off reaches, the system stops to run. 
Ŷ Memory Function 
The  system  memories  the setting  running  status  of  previous  power-off,  and  runs  automatically  with  the  setting 
running status before it power-off when it is energized again. If the unit is on before power-off, the compressor will 
3min delay protection when it is energized again. 
Ŷ Indicator Lamp, dual-8 digital pipe: 
a) When the unit runs, under cooling mode, cooling indicator lamp lights, dual-8 displays preset temperature. 
b) When the unit runs, under fan mode, fan indicator lamp lights, dual-8 does not display. 
c) When the unit runs, under dry mode, dry indicator lamp lights, dual-8 does not display. 
d) When the unit runs, under heating mode, heating indicator lamp lights, dual-8 displays preset temperature. 
Ŷ Setting button function 
a) ON/OFF button: It controls system’s switch. 
b) Mode button: Mode setting cycle with below sequence: Cooling only unit: cooling-> dry-> fan. 
c) Temp. ź button: Set temperature when the unit is on, the setting temperature decreases 1  or   per press ć
Temp.  ź button; it will never setting when the setting reaches to 16  or 61 . The button is not valid under auto, ć
dry and fan mode. 
d) Temp. Ÿ button: Set temperature when the unit is on, the setting temperature increases 1  or   per press ć
Temp.  Ÿ button; it will never setting when the setting reaches to 30  or 86 . The button is not valid under auto, ć
dry and fan mode.
