Forced operation function

• Forced cooling mode:
The compressor and outdoor fan continue to run and
the indoor fan runs at rated 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
• setting temperature

1.10 Timer function

• Timing range is 24 hours.
• Timer on. The machine will turn on automatically
when reaching the setting time.
• Timer off. The machine will turn off automatically
when reaching the setting time.
• Timer on/off. The machine will turn on automatically
when reaching the setting "on" time, and then turn
off automatically when reaching the setting "off"
time.
• Timer off/on. The machine will turn off automatically
when reaching the setting "off" time, and then turn
on automatically when reaching the setting "on" time.
• The timer function will not change the AC current
operation mode. Suppose AC is off now, it will not
start up firstly after setting the "timer off" function.
And when reaching the setting time, the timer LED
will be off and the AC running mode has not been
changed.
• The setting time is relative time.
• The AC will quit the timer function when it has
malfunction

1.11 Sleep function

 Page 18 
• 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 16°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 8 hours, after
which, the unit exits this mode and switches off.
• The timer setting is available in this mode.

1.12 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 and, in the
case of a sudden power failure, will restore those
setting automatically within 3 minutes after power
returns.
• 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
unit stands by.
1.13 Refrigerant Leakage Detection
The display area will show "EC" when the outdoor unit
detects refrigerant leakage.
1.14 8°C Heating
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.

1.15 ECO function

• Used to enter the energy efficient mode.
• Under cooling mode, press ECO button, the remote
controller will adjust the temperature automatically
to 24°C, fan speed of Auto to save energy (but only
if the set temperature is less than 24°C). If the set
temperature is more than 24°C and 30°C, press the
ECO button, the fan speed will change to Auto, the
set temperature will remain unchanged.
• When AC receives signals, such as switch off, Turbo
operation , Silence operation , Self clean operation
, Forced cooling operation, mode setting, Sleeping
