Cooling, heating and dehumidify). If you close the light key, all the display patterns will close.

② 

Double-8 display

According to the different setting of remote control, the nixie light may display the current temperature (the temperature scope is 

from 16

o

C to 30

o

C) and indoor ambient temperature. The set temperature displayed in auto cooling and fan mode is 25

℃ ,

The set 

temperature displayed in auto heating mode is 20

and the temperature will display H1 under the defrosting mode.(If you set the 

fahrenheit temperature display, the nixie light will display according to fahrenheit temperature)

(10) Protection function and failure display

E2: Freeze-proofing protection      E4: Exhausting protection      E5: Overcurrent protection
E6: Communication failure      H4: Overload protection
F1: Indoor ambient sensor start and short circuit (continuously measured failure in 30S)
F2: Indoor evaporator sensor start and short circuit (continuously measured failure in 30S)
F3: Outdoor ambient sensor start and short circuit (continuously measured failure in 30S)
F4: Outdoor condenser sensor start and short circuit (continuously measured failure in 30S, and dont measure within 10 minutes 

after defrosted)

F5: Outdoor exhausting sensor start and short circuit (continuously measured failure in 30S after the compressor operated 3 minutes)
H3: Overload protection of compressor      H5: Module protection
PH: High-voltage protection                PL: Low-voltage protection
P1: Nominal cooling and heating      P2: Maximum cooling and heating     
P3: Medium cooling and heating       P0: Minimum cooling and heating

(11) Drying Function

You may start or stop the drying function under the modes of cooling and dehumidify at the starting status (The modes of automatism, 
heating and air supply do not have drying function). When you start the drying function, after stop the machine by pressing the switch 
button, you should keep running the inner fans for 10 minutes under low air damper (The swing will operate as the former status 
within 10 minutes, and other load is stopped), then stop the entire machine; When you stop the drying function, press the switch 
button will stop the machine directly. When you start the drying function, operating the drying button will stop the inner fans and close 
the guide louver.

(12) Memory function when interrupting the power supply

Memory content: mode, swing function, light, set temperature and wind speed. After interrupted the power supply, the machine will 
start when recovering the power according to the memory content automatically. If the last remote control command has not set 
the timed function, the system will remember the last remote control command and operate according it. If the last remote control 
command has set timed function and the power supply is interrupted before the timed time, the system will remember the timed 
function of the last remote control command, the timed time will recounted form power on. If the last remote control command has 
set timed function, the time is out and the system is start or stop according to the set time when the power supply is interrupted, the 
system will remember the operation status before the power supply was interrupted, and do not carry out timed action; The timed 
clock will not remembered.

(13) Sleep function

In this mode, the system will select proper sleep curve to operate according to different set temperature. 

 If start up sleep function under cooling or drying mode, the system will increase set temperature automatically within a certain 

range to operate. 

 If start up sleep function under heating mode, the system will decrease set temperature automatically within a certain range to 

operate.
