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 (not including
the swing setting) and, in the case of a sudden power
failure, will restore those setting automatically within 3
minutes after power returns.
• If the unit was in forced cooling mode, it will run in
this mode for 30 minutes and turn to auto mode with
temperature set to 24°C.
• If there is a power failure while the unit is running, the
compressor starts 3 minutes after the unit restarts. If
the unit was already off before the power failure, the
compressor starts 1 minute after the unit restarts.
1.13 Refrigerant Leakage Detection
With this new technology, the display area will show “EC”
when the outdoor unit detects refrigerant leakage. This
function is only available in cooling mode.
1.14 Louver Position Memory Function
When starting the unit again after shutting down, its
louver will restore to the angle originally set by the user,
but the precondition is that the angle must be within
the allowable range, if it exceeds, it will memorize the
maximum angle of the louver. During operation, if the
power fails or the end user shuts down the unit in the
turbo mode, the louver will restore to the default angle.
1.15 8
°C
Heating(Optional)
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.
1.16 Self clean(Optional)
• If you press “Self Clean” when the unit is in cooling or
drying mode:
• For cooling models, the indoor unit will run in low
fan mode for a certain time, then ceases operation.
• For heat pump models, the indoor unit will run in
fan-only mode, then low heat, and finally in fan-
only mode.
• Self Clean keeps the indoor unit dry and prevents
mold growth.
1.17 Follow me(Optional)
• 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.
1.18 Silence (Optional)
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
F2. The indoor unit will run at faint breeze, which reduces
noise to the lowest possible level.
