CONTROL PANEL FEATURES
NOTE: The following control panels are for explanation purpose only. The control panel of the unit you
purchased may be slightly dierent according to the models. Your machine may not contain some
indicators or buttons. The actual shape shall prevail.
BUTTONS
ON/OFF power button.
SYSTEM FUNCTION SETTINGS
SHORT PRESS in sequence and use
or to navigate the menu. After 5 seconds of no activity on
the control panel, it will save the settings and close the menu:
1x = Fan speed setting
2x = Timer on setting
3x = Timer o setting
4x = Shutdown drainage (ON/OFF)
NOTE: ON setting will instruct the machine to pump out all water in reservoir every time the dehumidier is
powered o.
5x = Continuous operation setting of the fan (ON/OFF)
6x = Fahrenheit/Celsius
7x = Calibration of inlet humidity values
8x = Calibration of outlet humidity values
9x = Save and exit
LONG PRESS for 3 seconds to reset the WiFi module.
(Under humidity calibration setting, we can adjust it by press button + and -, with an adjustable range
of -10~10. For example, when the humidity display value of the dehumidier is observed to be 5% lower
than the humidity detected by separate detectors, the value needs to be adjusted to "5")
SHORT PRESS to start the water pump drainage.
LONG PRESS for 3 seconds to lock or unlock the screen. Lock screen feature cannot be activated when
machine is powered o.
SHORT PRESS WHEN SETTING TIMER: Cancels timer
Increase value on timer, humidity setting, and navigate menu.

After connecting the power, short press the "on-o key" to turn it on, the dehumidication function is
turned on, and the icon is displayed; press the power o again, the dehumidication function is turned o,
and the icon is not displayed.
SET HUMIDITY LEVEL
• During normal operation, current room humidity will show on the screen.
• Upon power-up, the default humidity value is 30%, AUTO fan speed when powered on.
• The humidity level can be set between 30-90%.
SHORT PRESS
or keys to adjust the set humidity level by 1%. The display will ash 3 times, and
after 5 seconds of no activity, the screen will resume showing the current room humidity reading.
LONG PRESS the
or keys to quickly adjust the percentage.
When the set humidity is 30%, SHORT PRESS the
key again to enter the CO continuous
dehumidication mode, the compressor will continue to run regardless of current room humidity.
Shows the humidity reading of the exhausted air.
AUTO DEFROST
When you see this icon on the display, it signals that the evaporator or ambient temperature has dropped
to a level where frost formation may occur. The machine will automatically initiate the defrost mode.
During defrost mode, the dehumidier will temporarily focus on melting any frost that has accumulated
on the evaporator. The dehumidier will automatically resume to the same settings and operation once
the defrost cycle is complete.
When this icon ashes, the machine is draining water.
1) Automatic Drainage: When the system receives the water full signal for ≥3 seconds, the water pump
will activate and drain the water. During this time, the compressor and fan motor will continue to run
and this icon will ash.
2) Manual Drain: After pressing the manual drain button
the water pump will activate and drain the
water. During this time, the compressor and fan motor will continue to run and this icon will ash.
NOTE: If the full water signal is not cleared in 60 seconds, an alarm will sound, the fault code E3 will show,
and the icon will continue to ash.
This machine features a water pump designed for ecient water removal up to a maximum 18ft vertical
height. If the hose exceeds this 18 ft. limit in height, it can lead to pump failure. To resolve this issue,
lower the hose height and attempt operation again.
Screen is locked and will not react to buttons.
LONG PRESS
for 3 seconds to activate and cancel lock screen.
Mobile app can also lock or unlock screen.
Lock screen feature cannot be activated when machine is powered o.
