24
fan is fixed at low speed.
When heating, the setting temperature decreases
1
℃
(be higher than 17
℃
) every one hour, 2 hours
later the setting temperature stops rising and
indoor fan is fixed at low speed. (Anti-cold wind
function has the priority).
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
℃
setting
temp.
If AC is off before power off and AC is required to
start up now, the compressor will have 1 minute
delay when power 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
℃
Heating(optional)
In heating operation, the preset temperature of the
air conditioner can be as lower as 8
℃
, which
keeps the room temperature steady at 8
℃
and
prevents household things freezing when the
house is unoccupied for a long time in severe cold
weather.
7.4.13 Self clean(optional)
For heat pump models which are provided with
this function, after running in cooling or drying
mode, if the user press “Self Clean” button on
remote controller, firstly, 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 signal which
sent from remote controller every 3 minutes, the
buzzer will not respond. When the unit is running
with follow me function, the PCB will control the
unit according to the temperature from 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 available,
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 remote controller signal,
but it will not affected by the setting temperature.
4) When the unit is running with follow me
function, if the PCB doesn’t receive any signal
from remote controller for 7 minutes or pressing
FOLLOW ME button again, the follow me function
will be turned off automatically, and the
temperature will control the unit according to the
