1.4 Fan Mode
When fan mode is activated:
• The outdoor fan and compressor are stopped.
• Temperature control is disabled and no temperature
setting is displayed.
• The indoor fan speed can be set to high, med, low, or
auto.
• The louver operations are identical to those in cooling
mode.
• Auto fan: In fan-only mode, AC operates the same as
auto fan in cooling mode with the temperature set at
24°C.
1.5 Cooling Mode
1.5.1 Compressor Control
When indoor room temp. T1 is lower than setting value,
the compressor and outdoor fan will shut off.
1.5.2 Indoor Fan Control
• In cooling mode, the indoor fan operates continuously.
The fan speed can be set to high, medium, low, or
auto.
• If the compressor ceases operations when the
configured temperature is reached, the indoor fan
motor operates at the minimum or configured speed.
1.5.3 Outdoor Fan Control
The On-off outdoor units have single fan speed. The
outdoor fan will run following the compressor except
when AC is in evaporator high temp. protection in heating
mode, condenser high temp. protection in cooling mode,
defrosting mode and the current protection.
1.5.4 Evaporator Temperature Protection
When evaporator temperature drops below a configured
value, the compressor and outdoor fan ceases operations.
1.6 Auto-mode
• This mode can be selected with the remote controller
.
• In auto mode, the machine selects cooling, heating, or
fan-only mode on the basis of

Heating*: In auto mode, cooling only models run the fan
• AC will run in auto mode in the below cases:
• Pressing the forced auto button.
• If AC is off, it will run in auto mode when the timer
on function is active.
• After setting the mode, AC will run in auto mode if
the compressor keeps not running for certain time.
1.7 Drying mode
• The compressor is cycled running with 10 minutes
on and then 5 minutes off. The indoor fan will keep
running at low speed.
• In drying mode, if room temperature is lower than
10
°C
, the compressor will stop and not resume until
room temperature exceeds 13
°C
.
• The evaporator anti-freezing protection is the same as
that in cooling mode.
1.8 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
1.9 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, 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.
