Other functions 

1.  Flap control 

1.1 Press the FLAP button on the remote controller continuously, the flap will alternate within the 

following eight positions: Auto, fixed (including the six positions of the flap from top to 

1,2,3,4,5,6) and swing.   

1.2  Auto: During the heating mode, the flap is set at position 5; during the cooling and 

dehumidification mode, the flap is at position 2; during the fan mode, it is at position 2. 

1.3 Fixed: The position of the flap is fixed at a certain position by the remote controller.   

1.4 Scanning: During cooling and fan mode, the flap sways among positions 1—4; during heating 

mode, the flap sways between positions 3—6. 

1.5 The default mode is Auto. 

1.6 When first turned on or turned off, the flap will turn to the furthermost positions to ensure well 

closing of the flap. When started, the flap will turn to the furthermost positions. After the grille 

is completely closed, it will turn to the setting position. 

 

2.  Man-machine communication 

 

2.1 The indoor controller has two temperature sensors to detect the room temperature: one in the 

controller and the other at the air inlet of indoor unit. The default airflow setting depends on 

that detected by the remote controller. The remote controller detects room temperature once 

every 20 seconds and transmits signals once every 3 minutes or when the detected 

temperature is not the same. If the indoor controller cannot receive signals for more than 10 

minutes, it will automatically start the temperature sensor

 

at the air inlet of indoor unit. 

Meanwhile, the man-machine communication symbol on the screen will go off. 

2.2  The man-machine communication mode cannot be cancelled by the switching-on and off 

operations. When the machine is switched off, the man-machine communication symbol will 

remain on. 

2.3 When the machine is turned on, the man-machine communication symbol will appear. When 

the air conditioner is started by the switch button of indoor unit, the man-machine 

communication symbol will go off. 

3.  Timing on and off 

3.1 Timing On: when the timing-on function is set by the remote controller, the timing-on function 

of the air conditioner is activated and the timer symbol lights up. When the setting time 

arrives, the machine starts with the setting mode after a signal from the remote controller is 

received. If no signal is received at the setting time, the machine will run by automatic 

settings. At the same time, the man-machine communication symbol goes off. 

3.2  Timing Off: when the timing-off function is set by the remote controller, the timing-off 

function of the air conditioner is activated and the timer symbol lights up. When the setting 

time arrives, the machine shuts off after a signal from the remote controller is received. If no 

signal is received at the setting time, the machine will automatically shut off. At the same 

time, the man-machine communication symbol goes off. 

3.3  The timing mode cannot be cancelled by the switching-on and off operations. When the 

machine is switched off, the timer symbol remains on.
