(10) Display
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
ºF
from 61 to 86 ) and indoor ambient temperature. The heating and air supply temperature will display 77
the temperature will display 18
set the fahrenheit temperature display, the nixie light will display according to fahrenheit temperature)
(11) Protection function and failure display
E2: Freeze-proofing protection
E6: Communication failure
F1: Indoor ambient sensor start and short circuit (continuously measured failure in 20S)
F2: Indoor evaporator sensor start and short circuit (continuously measured failure in 20S)
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
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
PH: High-voltage protection
P1: Nominal cooling and heating
P3: Medium 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 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.
(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.
