9.4.7 Economy function
9.4.7.1 The sleep function is available in
cooling, heating or auto mode.
9.4.7.2. Operation process in sleep mode is as
follow:
When cooling, the setting temperature rises 1
℃
(be lower than 30
℃
) every one hour, 2 hours
later the setting temperature stops rising and
the indoor 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).
9.4.7.3 Operation time in sleep mode is 7 hours.
After 7 hours the AC quits this mode and turns
off.
9.4.7.4 Timer setting is available
9.4.8 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.
9.4.9 Refrigerant Leakage Detection
With this new technology, the display area will
show
“EC” when the outdoor unit detects
refrigerant leakage.
9.4.10 8
℃
Heating function
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.
9.4.11 Self clean function
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.
9.4.12 Follow me function
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.
