Basic Display
1) When the unit is energized, the display symbol display, then only power lamp is light.
2) When use remote control to turn on the unit, the running LED is light, and the current setting running mode
lamp displayed at the same time.
COOLING: running lamp and cooling lamp are light; HEATING: running lamp and heating lamp are light;
DRY: running lamp and dry lamp are light; FAN: running lamp and fan lamp are light;
AUTO: auto lamp, running lamp and actual running mode lamp are light.
(3) If turn off the LIGHT button, all the display is off (it is valid when the unit is OFF).
(4) After set SLEEP function, the display maintains the original display status, it means the light switch does not
influence sleep function.
Dual-8 Display

O
77 F for cooling and fan under auto mode, and display 68 F for heating, and the cooling controller displays 77 F.
O
The temperature range is 32-86 F when the indoor temperature displays.
Fan Speed Display
There are 3 status dynamic circle display for fan symbol, they are middle two segments, middle four segments
and display six segments, and the middle two segments is displaying. The fan speed symbol blinks the fastest
when remote control super-fan; the fan speed symbol blinks the lowest when remote control low-fan; the blink
speed of display symbol is between high fan and low fan when remote control med fan; the blink speed of display
depends on the indoor actual running speed when remote control auto fan speed; if the indoor fan motor stops, it
blink display at the lowest speed.
Indoor Unit Malfunction Lamp Display
Note: The malfunction code will circulate display when different malfunctions exist together. The indicator will light
0.5S and display 0.5S when it blinks. The indoor temperature sensor malfunction will not be inspected during
defrost, or oil return period.

Timer Function
General timer:
a. TIMER ON: The timer on can be set when the unit is OFF, the controller will run under original setting mode
when the time of timer on reaches, the timer space is 0.5h, and setting range is 0.5-24h.
b. TIMER OFF: The timer off can be set when the unit is ON, the unit is OFF when the timer time reaches, the
timer space is 0.5h, and setting range is 0.5-24h.
Clock timer:
a. TIMER ON: If set timer on when the unit is running, it will keep running. if set the timer on when the unit is off,
the unit will run with the pre-setting mode when the time of setting timer on reaches.
b. TIMER OFF: If set timer off when the unit is off, when setting timer off, the unit will maintain stand-by status; if
set timer off when the unit is on, when the time of setting timer off reaches, the system will stop to run.
c. TIMER changing: When the unit under timer status, it can set ON and OFF by remote control, and reset timer
time, the unit will run under the last setting status.
Set timer on and timer off together when the unit is running, the unit will maintain the current status, once the time
of setting timer off reaches, the unit will stop to work.
Set timer on and timer off together when the unit is off, the unit will maintain off status until the time of timer on
reaches, the unit will start to work, hereafter the time of timer on reaches everyday, the unit will run under the
original setting mode, and the unit stop to work when the time of timer off reaches.
When the time of setting timer on and setting timer off is the same, the unit is off.
Memory Function
Memory contents: mode, swing (up and down), light, set Temp., set fan speed, general timer (clock timer doesn't
memory)
The unit will on automatically with memory content after re-energized.
There is no setting timer function in the last remote control order, and the system memory the last remote control
order and working under that setting method.
There is general timer function in the last remote control order, the system is energized before the timer time
haven't reach, the unit will memory timer function of the last remote control order after re-energized, and the
timer time will star to calculate after re-energized.
There is timer function in the last remote control order, but the timer time reaches, the system will de-energize
after timer on and timer off, after re-energized, the system will memory the running status which before power-off,
and no timer action; the clock timer doesn't memory.
U-TOUCH Function
If controller receives U-TOUCH command, it will run at the ambient temp sent by remote control (but it will also
run at sampling temp. of AC temp sensor itself except defrost and anti-cool air). The remote control will send
ambient temp to controller every 10min, so if the controller hasn"t received ambient temp from remote control
after 11min, it will run at temp. of AC itself. If this function is not set, all ambient temp will adopt sampling value of
AC temp. sensor itself.
Turbo Function
The TURBO function can be set only under COOLING and HEATING mode, when controller receiving turbo
order, the indoor fan motor will run with high speed, and send turbo signal and high speed to outdoor unit.
After energization, up & down swing motor will totate guide louver to position 0
to close air outlet. After turn on the unit, if swing function has not been set, up &
down guide louver will clockwise turn to position D under heating mode, or
clockwise turn to level position L1 under other modes. If the unit is turn on with
swing function setting, guide louver will swing between L and D. There are 7
kinds of swing states of guide louver. Position L,A,B,C,D, swing between L and
D, stop between L and D (included angle L and D is equiangular). Upon stop of
unit, guide louver will close to position 0. Swing action is valid only when swing
command is set and indoor fan is running.
