7.4.8.3 Operation time in sleep mode is 7 hours. After 7
hours the AC quits this mode and turns off.
7.4.8.4 Timer setting is available.
7.4.9 Auto-Restart function
The indoor unit is equipped with auto-restart function,
which is carried out through an auto-restart module.
In case of a sudden power failure, the module
memorizes the setting conditions before the power
failure. The unit will resume the previous operation
setting (not including swing function) automatically
after 3 minutes when power returns.
If the memorization condition is forced cooling mode,
the unit will run in cooling mode for 30 minutes and
turn to auto mode as 24˚C setting temp.
If AC is off before powered off and AC is required to
start up now, the compressor will have 1 minute delay
when powered on. Other conditions, the compressor
will have 3 minutes delay when restarts.
7.4.10 Refrigerant Leakage Detection
With this new technology, the display area will show
“EC” when the outdoor unit detects refrigerant
leakage.
7.4.11 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.
7.4.12 8˚C
Heating(optional)
In heating operation, the preset temperature of the air
conditioner can be as low as 8˚C, which keeps the
room temperature steady at 8˚C and prevents
household things from freezing when the house is
unoccupied for a long time in severe cold weather.
7.4.13 Self clean(optional)
For heat pump models provided with this function: After
running in cooling or drying mode, once the user presses
“Self Clean” button on remote controller, the indoor unit
runs in fan only mode for a while, then low heat
operation and finally runs in fan only again. This function
can keep the inside of indoor unit dry and prevent
breeding of mold.
7.4.14 Follow me (optional)
1)
If the indoor PCB receives the signal which results
from pressing the FOLLOW ME button on remote
controller, the buzzer will emit a sound and this indicates
the follow me function is initiated. But when the indoor
PCB receives a signal sent from the remote controller
every 3 minutes, the buzzer will not respond. When the
unit is running with the FOLLOW ME function, the PCB
will control the unit according to the temperature from
the follow me signal, and the temperature collection
function of room temperature sensor will be shielded,
but the error detective function of room temperature
sensor will be still valid.
2) When the FOLLOW ME function is active, the PCB
will control the unit according to the room
temperature from the remote controller and the
setting temperature.
3)
The PCB will take action to the mode change
information from the remote controller signal, but it will
not b e affected by the setting temperature.
4)
When the FOLLOW ME function is active and the
PCB doesn’t receive any signal from the remote
controller for 7 minutes or the FOLLOW ME button is not
pressed again, the FOLLOW ME function will be turned off
automatically. The PCB will control the unit according
to the room temperature detected from its own room
temperature sensor and setting temperature.
7.4.15 Silence operation(optional)
Press the “silence” button on remote controller to initiate
SILENCE function. When the Silence function is activated,
the compressor running frequency will keep lower than
F2 and the indoor unit will bring faint breeze, which will
reduce the noise to the lowest level and create a quiet
and comfortable room for you.
