feature.
*In case change of set temperature by remote control meets the condition of unit
shut down or unit is powered off manually, the operation is not restricted by the 2-minute
non-response feature and will shut down immediately.
*Anti Current Surge: External fan starts 2s after compressor is on. *Timed Power On
& Off Feature *Sleep Control Feature
*Four-way Valve Control: Four-way valve is on 10s prior to compressor startup and
off 2 minutes and 30 seconds after compressor shutdown.
*Anti Cold Wind Operation:
（
1
）
Compressor operation or compressor operation after defrosting. When indoor
heat exchanger temperature is below 23 ℃ , indoor fan is off; when indoor heat
exchanger temperature is above 23
℃
, fan operates in weak wind mode.
（
2
）
If, after 4 minutes, coil temperature can not exceed 38 ℃ , fan will operate at set
speed.
（
3
）
If coil temperature exceed 38
℃
, fan will operate at set speed.
（
4
）
If coil temperature falls below 38
℃
when compressor is running, fan will still
operate at set speed.
*Residual Heat Blow: Temperature sensor is off: If coil temperature is above 23 ℃ ,
fan will enter weak wind mode, if coil temperature below 23
℃
, indoor fan will stop.
Remote Control Shut Down: Deflector will close after set wind blows for 1 minute.
*Automatic Temperature Compensation in Heating Mode
1 Condition: Compressor shutdown time is less than 5 minutes
2. Operation Rule:
1
）
Ts =Trc+5
℃
+
（
Trc -Tt [The instant when compressor starts up]
）
2
）
Trc-Tt[The instant when compressor starts up]
≤
2 ℃
Note: The above two conditions are not applicable to initial start-up.
3
）
Press “–”temperature key on remote control, and resume Ts =Trc+5 ℃
operation; Press “+”temperature key on remote control, it will operate based on
automatic compensation set value.
4
）
If Trc -Tt[before compressor is on]
≤
0
℃
, it will operate as per Ts=Trc+5.
3. If ventilation door is in healthy up-flow position, set temperature in heating mode
will be increased by 2 ℃ on its original basis.
5.Defrosting Mode
Air fan will engage in anti cold wind operation based on the data sent by heat
exchanger temperature sensor. Sensor fault will not be checked within the first 2 minutes
after exiting defrosting mode.
6. Negative Ion Health Feature Control
When receiving remote control signal, if fan is operating, negative ion generator will
start working to discharge negative ion.
If air fan is off, negative ion generator will be off.
When negative ion generator is off, if health feature is set, then negative ion
generator will turn on when fan start operation again.
7. Timed Operation
