1.7 Auto-mode
• This mode can be selected with the remote controller
and the setting temperature can be changed between
17°C~30°C.
• In auto mode, the machine selects cooling, heating, or
fan-only mode on the basis of ∆T (∆T =T1-Ts).
∆T Running mode
∆T>2℃ Cooling
-2℃≤∆T≤2℃ Fan-only
∆T<-2℃ Heating*
Heating*: In auto mode, cooling only models run the fan
• The louver operates same as in relevant mode.
• If the machine switches mode between heating and
cooling, the compressor will keep stopping for certain
time and then choose mode according to T1-Ts.
• If the setting temperature is modified, the machine will
choose running function again.
1.8 Drying mode
• Indoor fan speed is fixed at breeze and can’t be
changed. The louver angle is the same as in cooling
mode.
• All protections are active and the same as that in
cooling mode.
1.9 Forced operation function
• Forced cooling mode:
The compressor and outdoor fan continue to run and
the indoor fan runs at low speed. After running for 30
minutes, the AC will switch to auto mode with a preset
temperature of 24°C.
• Forced auto mode:
Forced auto mode operates the same as normal auto mode
with a preset temperature of 24°C.
• The unit exits forced operation when it receives the
following signals:
• Switch on
• Switch off
• Timer on
• Timer off
• Changes in:
• mode
• fan speed
• sleeping mode
• Follow me
1.10 Sleep function
• The sleep function is available in cooling, heating, or
auto mode.
• The operational process for sleep mode is as follows:
• When cooling, the temperature rises 1°C (to not
higher than 30°C) every hour. After 2 hours, the
temperature stops rising and the indoor fan is fixed
at low speed.
• When heating, the temperature decreases 1°C(to
not lower than 17°C) every hour. After 2 hours, the
temperature stops decreasing and the indoor fan is
fixed at low speed. Anti-cold wind function takes
priority.
• The operating time for sleep mode is 7 hours, after
which, the unit exits this mode and switches off.
• The timer setting is available in this mode.
1.11 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.
1.12 Refrigerant Leakage Detection
With this new technology, the display area will show “EC”
when the outdoor unit detects refrigerant leakage.
1.13 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.
1.14 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.
