3.7 Drying mode
• In drying mode, AC operates the same as auto fan in
cooling mode.
• All protections are activated and operate the same as
they do that in cooling mode.

If the room temperature is lower than 10°C, the
compressor ceases operations and does not resume until
room temperature exceeds 12°C.

The compressor and outdoor fan continue to run and
the indoor fan runs at breeze speed. After running for 30
minutes, the AC will switch to auto mode with a preset
temperature of 24°C(76°F).
• Forced auto mode:

with a preset temperature of 24°C(76°F).

If the unit is off now, it does not start up immediately
after the “timer off” function is set. When the setting
time is reached, the timer LED switches off and the

3.10 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/86°F) 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/60.8°F) 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.
• The timer setting is available in this mode.
3.11 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 and in the
case of a sudden power failure, will restore those
setting automatically within 3 minutes after power
returns.
