(1) Under this mode, the fan and the up swing will operate at setting status. The temperature setting range is 16~30ºC.
(2) The unit is stopped because of malfunction of outdoor unit or protection. The indoor unit keeps original operation status and the
error code is displayed.
(3) Indoor unit is stopped due to mode shock.
2. Drying mode
(1) Under this mode, the fan operates at low speed and the swing operates at setting status. The temperature setting range is
16~30ºC.
(2) The unit is stopped because of malfunction of outdoor unit or protection. The indoor unit keeps original operation status and the
error code is displayed.
3. Heating mode
(1) Under this mode, the temperature setting range is 16~30ºC.
(2) Working condition and process for heating
When the unit is turned on under heating mode, the indoor unit turns to cold air prevention status. When the unit is turned off and the
indoor unit has been started up before, the indoor unit blows the residual heat.
(3) Protection function: When the compressor is stopped due to malfunction under heating mode, the indoor unit blows the
residual heat.
(4) Blow residual heat
When the unit stops operation as it reaches the temperature point, indoor unit will continue to run for 60s. The fan speed cant be
switched during blowing residual heat period. The upper horizontal louver will turn to the defaulted position in cooling. When the unit
operates under heating mode or auto heating mode, compressor will be turned on and the corresponding electric expansion valve is
more than 65 and the unit stops operation during the operation status of indoor unit. The upper horizontal louver will turn to the
defaulted position in heating mode. The indoor unit operates at low speed for 10s and then the unit stops operation.
(5) Defrosting, oil-returning
As it received the signal of defrosting and oil-returning from outdoor unit, the upper horizontal louver will turn to the minimum angle in
cooling. 10s later, the in door fan stop operation. During defrosting and oil-returning process and they are quitted within 5mins, all
malfunctions for indoor tube temperature sensor wont be detected.
4. Working process for AUTO mode (Mode judgment will be performed every 30s)
Under AUTO mode, standard cooling Tpreset=25ºC (77ºF), standard heating Tpreset=20ºC (68ºF), and standard fan Tpreset= 25ºC
(77ºF).
(1) When Tamb≥26ºC (79ºF), the unit operation in cooling mode;
(2) Heating pump unit: When Tamb≤19ºC (66ºF), the unit operates in heating mode;
(3) Cooling only unit: Tamb≤19ºC (66ºF), the unit operates in fanmode;
(4) When 19ºC<Tindoor amb.<26ºC, if it turns to auto mode as the unit is turned on for the rst time the unit will operates at auto fan
mode. If it switch to auto mode from other modes, the unit will keep previous operation mode (when it turns to dry mode, the unit
operates at auto fan mode).
(5) Protection function
Protection function is the same as that in cooling or heating mode.
5. Fan mode
Under fan mode, only indoor fan and swing operates. When it operates at auto fan speed, it will operate according to auto fan speed
condition in cooling.
6. Mode shock
If the mode shock is 1 which is received by indoor unit from outdoor unit, the loads of indoor unit (indoor unit, auxiliary heating,swing)
stop operation and the error code is displayed. The mode sent to outdoor unit is still remote control receiving mode. The unit will be
turned off during mode shock.
If timer ON is reached, and the mode shock is 1 which is received by indoor unit from outdoor unit, the loads of indoor unit (indoor
unit,auxiliary heating, swing) stop operation and the error code is displayed. The mode sent to outdoor unit is still remote control receiving
mode.
7. Other control
7.1 Buzzer
Upon energization or availably operating the unit or remote controller, the buzzer will give out a beep.
7.2 Auto button
If this button is pressed, the unit will operate in AUTO mode and indoor fan will operate at auto speed; meanwhile, the swing motor
operates. Press this button again to turn off the unit.
7.3 8 ºC heating function
Under heating mode, press TEMP+CLOCK buttons simultaneously. Under this mode, “cold air prevention protection” will be shielded.

7.4 I FEEL function
When I FEEL command is received, the controller will operate according to the ambient temperature sent by the remote controller (For
defrosting and cold blow prevention, the unit operates according to the ambient temperature sensed by the air conditioner). The
remote controller will send ambient temperature data to the controller every 10min. When the data has not been received after
11mins,the unit will operate according to the temperature sensed by the air conditioner. If I FEEL function is not selected, the ambient
temperature will be that sensed by the air conditioner. I FEEL function will not to be memorized.
7.5 Timer function
General timer and clock timer functions are compatible by equipping remote controller with different functions.
(1)General Timer
Timer ON can be set at unit OFF. If selected ON time is reached, the unit will start to operate according to previous setting status.
Time setting range is 0.5-24hr in 30-minute increments.
Timer OFF can be set at unit ON. If selected OFF time is reached, the unit will stop operation. Time setting range is 0.5-24hr in
30-minute increments.
(2)Clock Timer
Timer ON
If timer ON is set during operation of the unit, the unit will continue to operate. If timer ON is set at unit OFF, upon ON time reaches
the unit will start to operate according to previous setting status.
Timer OFF
If timer OFF is set at unit OFF, the system will keep standby status. If timer OFF is set at unit ON, upon OFF time reaches the unit
will stop operation.
Timer Change
Although timer has been set, the unit still can be turned on/off by pressing ON/OFF button of remote controller. You can also set
the timer once again, and then the unit will operate according to the last setting. If timer ON and timer OFF are set at the same time
during operation of the unit, the unit will keep operating at current status till OFF time reaches. If timer ON and timer OFF are set at
the same time at unit OFF, the unit will keep stop till ON time reaches. In the future’s every day, the system will operate according to
presetting mode till OFF.
7.6 Sleep function
This mode is only valid in cooling and heating modes. The unit will select proper sleep curve to operate according to different set
temperature.
7.7 Compulsory defrosting function
When the unit is turned on in heating by remote controller and the set temperature is 16oC, press “+,-,+,-,+,-”continuously within 5s,
the indoor unit turns to compulsory defrosting setting and it will send compulsory defrosting mode to outdoor unit.
When indoor unit received the compulsory defrosting signal from outdoor unit, the indoor unit will quit from the compulsory defrosting
setting and it will cancel to send compulsory defrosting mode to outdoor unit.
7.8 Refrigerant recovery function
Turn to Freon recovery mode: After the unit is energized for 5min, and the unit is turned on at 16ºC under cooling mode, press light
button on remote controller for 3 times successively within 3s to turn to Freon recovery mode. Fo is displayed and it will send Freon
recovery mode to outdoor unit.
Quit from Freon recovery mode:After it turns to Freon mode, if it receives any signal from remote controller or it turns to Freon
recovery mode for 25 mins, it will quit from Freon recovery mode.
Turn to the action for Freon recovery mode: indoor unit will be turned on in cooling mode. The fan speed is super-high fan speed and
the set temperature is 16oC. The horizontal louver will turn to the minimum operation angle.
Quit the action for Freon recovery mode: The indoor fan operates at the previous set status by remote controller.
7.9 Pilot run function
When the set temperature is 30oC under cooling mode, press “+,-,+,-,+,-”continuously within 5s, the indoor unit turns to pilot run
setting mode and it will send pilot run mode to outdoor unit.
Pilot run mode: it operates under cooling mode and “dd” is displayed.
Quit the pilot run mode and indoor unit cancels “dd” display. If it receives “wrong wire connection of malfunction of expansion valve”
from outdoor unit, “dn” will be displayed.
