then the wind blade will swing between L and D. The air deflector has 7 swinging states: Location L, Location A, Location B, Location C,
Location D, Location L to Location D, stop at any location between L-D (the included angle between L~D is the same). The air deflector will be
closed at 0 Location, and the swinging is effectual only on condition that setting the swinging order and the inner fan is running. The indoor fan
and compressor may get the power when air deflector is on the default location.

(10) Basic Display
①
Operation pattern and mode pattern display
All the display patterns will display for a time when the power on, the operation indication pattern will display in red under standby status.
When the machine is start by remote control, the indication pattern will light and display the current operation mode (the mode light includes:
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°C to
30°C) and indoor ambient temperature. The set temperature displayed in auto cooling and fan mode is 25°C and the set temperature displayed
in auto heating mode is 20°C. Under heating mode, nixie tube displays H1 or heating indicator is off 0.5s and blinks 10s in defrosting.(If you
set the fahrenheit temperature display, the nixie light will display according to fahrenheit temperature)
(11) 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
(12) 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 2 minutes under low air damper (The swing will operate as the former status within 2 minutes, cooling
indicator is on for 0.5s and then off for 10s in drying 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.
(13) 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.
