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.
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 to 30 ) and indoor ambient temperature. The heating and air supply temperature will display 25 under
auto-mode, the temperature will display 20
under the auto-heating mode, 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)
(11) Protection function and failure display
E2: Freeze-proofing protection E4: Exhausting protecti on E5: Overcurrent protection
E6: Communication failure
F1: Indoor ambient sensor start and short circuit (continuously measured failure in 5S)
F2: Indoor evaporator sensor start and short circuit (continuously measured failure in 5S)
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 don’t 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 test P2: Maximum cooling and heating test
P3: Medium cooling and heating test P0: Minimum cooling and heating test
(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 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 wi
(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.
ll stop the inner fans and close the guide louver.

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.
