Indoor Fan Running Rules
When the compressor is on, the indoor fan can be set to
high/med/low/auto/mute. When the indoor unit coil temperature is
low, the anti−cold air function starts and the indoor fan motor runs
at a low speed and the speed can not be changed. When the
temperature is lower than the setting value, the indoor fan motor
stops.
When the indoor temp reaches the setting temperature, the
compressor stops, the indoor fan motor runs at the minimum speed
or setting speed. The anti−cold air function is valid. The indoor fan
is controlled as shown in Fig. 14.

DEFROSTING Mode
The air conditioner enters the DEFROSTING mode according to
the T3 temperature value and the T3 temperature change value
range plus the compressor running time.
During the DEFROSTING mode, the compressor continues to
runs, the indoor and outdoor motors stop, and the indoor unit
defrost lamp illuminates and
appears.

Auto−Mode
This mode can be chosen with the remote controller and the setting
temperature can be changed between 62.6
_F(17_C)~86_F(30_C).
In the AUTO mode, the machine chooses the COOLING,
HEATING or FAN−ONLY mode according to ΔT (ΔT =T1−Ts).
Fig. 17 – AUTO Mode
The indoor fan runs under auto fan in the relevant mode. The
louver operates same as in relevant mode. If the machine switches
mode between HEATING and COOLING, the compressor stops
for a certain time and then chooses the mode according to T1−Ts. If
the setting temperature is modified, the machine chooses the
running function again.
DRYING Mode
Indoor Fan Speed is Fixed
Indoor fan speed is fixed at breeze and can not be changed. The
louver angle is the same as in the COOLING mode.
Low Indoor Room Temperature Protection
In the DRYING mode, if the room temperature is lower than 50
_F
(10
_C), the compressor stops and will not resume until the room
temperature exceeds 53.6
_F (12_C).
