• Forced defrosting mode:
• Press AUTO/COOL button continuously for 5 sec. under forced cooling mode to enter this mode.
• Indoor fan will stop, defrosting lamp will light on.
• Quit this mode and turn off the unit when:
- Quit normal defrosting.
- Turn off by RC.
- Press AUTO/COOL button continuously for 5 sec. again.
4.3.8 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 8 hours, after which the unit exits this mode and does not
switch off.
4.3.9 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, it 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.
4.3.10 Refrigerant Leakage Detection
With this new technology, the display area will show “EC” when the outdoor unit detects refrigerant
leakage.
4.3.11 Ionizer / Plasma (for some models)
Press “Fresh” for at least 2 seconds on the remote control to enable the IONIZER function.
While this function is active, the Ionizer / Plasma Dust Collector (depending on models) is energized
and will help to remove pollen and impurities from the air.
4.4 Optional functions
4.4.1 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.
4.4.2 Self Clean
• If you press “Self Clean” when the unit is in cooling or drying mode:
- For cooling only models, the indoor unit will run in low fan mode for a certain time, then
ceases operation.
- For heat pump models, the indoor unit will run in fan-only mode, then low heat, and finally in
fan-only mode.
• Self Clean function keeps the indoor unit dry and prevents mold growth.
• When match with multi outdoor unit, this function is disabled.
