time is reached, the timer LED switches off and the 
unit running mode remains unchanged.

•  The timer uses relative time, not clock time

1.11  Sleep function

•  The sleep function is available in cooling, heating, or 

auto mode.

•  The operational process for sleep mode is as follows:

•  When cooling, the temperature rises 1°C (to not 

higher than 30°C/86°F) every hour. After 2 hours, 
the temperature stops rising and the indoor fan is 
fixed at low speed.  

•  When heating, the temperature decreases 1°C(to 

not lower than 16°C/60.8°F) every hour. After 2 
hours, the temperature stops decreasing and the 
indoor fan is fixed at low speed. Anti-cold wind 
function takes priority.

•  The operating time for sleep mode is 8 hours, after 

which, the unit exits this mode.

•  The timer setting is available in this mode.

1.12  Auto-Restart function

•  The indoor unit has an auto-restart module that 

allows the unit to restart automatically. The module 
automatically stores the current settings and in the 
case of a sudden power failure, will restore those 
setting automatically within 3 minutes after power 
returns.

1.13  8

°C

 Heating

In heating mode, the temperature can be set to as low 
as 8°C, preventing the indoor area from freezing if 
unoccupied during severe cold weather.

1.14  Follow me

•  If you press “Follow Me” on the remote, the indoor 

unit will beep. This indicates the follow me function is 
active. 

•  Once active, the remote control will send a signal 

every 3 minutes, with no beeps. The unit automatically 
sets the temperature according to the measurements 
from the remote control.

•  The unit will only change modes if the information 

from the remote control makes it necessary, not from 
the unit’s temperature setting.

•  If the unit does not receive a signal for 7 minutes or 

you press “Follow Me,” the function turns off. The 
unit regulates temperature based on its own sensor 
and settings.

1.15  Silence

•  Press “Silence” on the remote control to enable the 

SILENCE function. While this function is active, the 
compressor frequency is maintained at a lower level 
than F3. The indoor unit will run at faint breeze(1%), 
which reduces noise to the lowest possible level. 

•  When match with multi outdoor unit, this function is 

disabled. 

1.16  ECO Function

•  Used to enter the energy efficient mode.

•  Under cooling mode, press ECO button, the remote 

controller will adjust the temperature automatically 
to 24°C/75°F, fan speed of Auto to save energy (but 
only if the set temperature is less than 24°C/75°F). 
If the set temperature is more than 24°C/75°F and 
30°C/86°F, press the ECO button, the fan speed will 
change to Auto, the set temperature will remain 
unchanged.

•  When pressing the ECO button, or modifying the 

mode or adjusting the set temperature to less than 
24°C/75°F, the AC will quit the ECO operation.

•  Operation time in ECO mode is 8 hours. After 8 hours 

the AC quits this mode.

1.17  Electrical energy consumption control 

function 

Press the “Gear” button on remote controller to enter the 
energy efficient mode in a sequence of following:

Turn off the unit or activate ECO, sleep, Super cool, 
8°C Heating, Silence or self clean function will quit this 
function.

1.18  Active Clean function

•  The Active Clean Technology washes away dust, mold, 

and grease that may cause odors when it adheres to 
the heat exchanger by automatically freezing and then 
rapidly thawing the frost. The internal wind wheel 
then keeps operating to blow-dry the evaporator, thus 
preventing the growth of mold and keeping the inside 
clean.

•  When this function is turned on, the indoor unit 

display window appears “CL”, after 20 to 45 minutes, 
the unit will turn off automatically and cancel Active 
Clean function.
