Default Setting
When the unit restarts after a power failure, it will default to the factory
settings
(AUTO mode, AUTO fan, 76°F (24°C)). This may cause inconsistencies
on the remote control and unit panel. Use your remote control to update
the status.
Auto-Restart
In case of power failure, the system will immediately stop. When power
returns, the Operation light on the indoor unit will flash. To restart the
unit, press the ON/OFF button on the remote control. If the system has an
auto restart function, the unit will restart using the same settings.
Three-Minute Protection Feature
A protection feature prevents the unit from being activated for
approximately 3 minutes when it restarts immediately after operation.
Louver Angle Memory Function
Some models are designed with a louver angle memory function. When
the unit restarts after a power failure, the angle of the horizontal louvers
will automatically return to the previous position.
The angle of the horizontal louver should not be set too small as
condensation may form and drip into the machine. To reset the louver,
press the manual button, which will reset the horizontal louver settings.
Heat Exchanger Dust Removal Function
This feature helps keep the outdoor coil cleaner and may extend the
duration between regular maintenance intervals depending on local
conditions. When the unit is turned off, a 10 seconds delay occurs and the
outdoor fan runs in reverse rotation for 70 seconds to blow off loose
accumulated dust and debris.
Sleep Operation
The SLEEP function is used to decrease energy use while you sleep (and
you do not need the same temperature settings to stay comfortable). This
function can only be activated via remote control. And the Sleep function
is not available in FAN or DRY mode.
Press the SLEEP button when you are ready to go to sleep. When in
COOL mode, the unit will increase the temperature by 2°F (1°C) after 1
hour, and will increase an additional 2°F (1°C) after another hour.
When in HEAT mode, the unit will decrease the temperature by 2°F (1°C)
after 1 hour, and will decrease an additional 2°F (1°C) after another hour.
The sleep feature will stop after 8 hours and the system will keep running
with final situation.
