BASIC OPERATING INSTRUCTIONS
BATTERY REPLACEMENT
1. Remove the battery compartment cover from the back of
the remote control by lifting it in the direction of the arrow.
2. Take out the depleted batteries.
3. Insert two new 7# AAA (1.5 V) dry batteries, making sure to
match the polarity markings (+ and –) shown on the remote
control.
4. Replace the compartement cover by sliding it into place.
NOTES:
▪ Do not use rechargeable batteries.
▪ Replace with new batteries of the same brand when re-
placement is required.
▪ Do not dispose of used batteries with other domestic
waste. Separate collection of such waste for special
treatment is necessary.
USAGE RECOMMENDATIONS
▪ Direct the remote control toward the signal receiver of the
indoor unit for optimal use.
▪ In order for the signal to be transmitted successfully, the dis-
tance between the remote control and the indoor unit must
be less than 8 meters (26 feet) and within a 60° angle.
▪ Make sure that there are no objects between the remote con-
trol and the signal receiver of the indoor unit that could block
the signal.
▪ Never leave the remote control exposed to the sun.
▪ Keep the remote control at a distance greater than 1 meter (3
feet) from appliances or devices such as televisions, uores-
cent lamps, wireless phones or other electrical appliances to
avoid signal interference.
▪ When not using the remote control for an extended period of
time, please remove the batteries so as not to wear them out
needlessly.
▪ A blurry or blank display screen on the remote control may
indicate a low battery level. In such a case, replace the bat-
teries with new ones.
▪ If the remote control is lost or damaged, use the emergency
button to turn the indoor unit on or off.

OPERATION GUIDE
FUNCTION DESCRIPTION AND SETTING
▪ This remote control is for general use. It can be used for multi-function heat pumps and air conditioners.
For the functions that the model does not have, if you press the corresponding button on the remote con-
trol, the unit will keep its initial operating status.
▪ Immediately after the power is turned on, the indoor unit will make a beep and the power indicator " " will
light up on the indoor unit display. After this point, you can operate the heat pump using the remote control.
▪ In operating state, when a button on the remote control is pressed, the signal symbol " " on the display
screen of the remote control will blink once and the indoor unit will emit a beep. This indicates the signal
has been successfully received by the unit.
▪ Models with WiFi control or a wired thermostat must rst be controlled by a standard remote in Auto
mode. Following this, the setting of the temperature can be made via the WiFi mobile App or the wired
thermostat.
▪ This remote control can set the temperature in Auto mode. When used with a unit that does not have the
Auto mode temperature setting function, the temperature set in this mode will be invalid, or the set tem-
perature displayed on the unit will not be the same as that on the remote control.
POWER ON/OFF
Allows the user to power the unit on or off.
Press the POWER button ( ) to turn on the unit. Press again to turn off the unit.
OPERATION MODE SETTING
Allows the user to select an operation mode in accordance with their needs.
Press the MODE button ( ) on the remote control to select the desired operation mode. With each press
of the button, the setting options cycle through in the following order:
Auto Mode: In this operation mode, the unit will automatically use the best presets based on the ambient
room temperature.
Cooling Mode: In this operation mode, the unit will cool the room to the desired temperature as well as
remove moisture from the air.
Drying Mode: In this operation mode, the unit will reduce the humidity in the air to make the room more
comfortable. Fan speed is automatically set to Low speed and cannot be adjusted.
NOTE: Under this mode, the temperature can be displayed on the indoor unit and the set temperature
can be adjusted. Use the arrow buttons (▲or ▼) to adjust the temperature to the desired setting.
Auto Cooling Drying Ventilation Heating

12
OPERATION GUIDE
Ventilation Mode : In this operation mode, the unit will blow uncooled/unheated air. Set temperature cannot
be adjusted.
Heating Mode: In this operation mode, the unit will heat the room to the desired temperature.
TEMPERATURE SETTING
Allows the user to set the temperature in accordance with their needs.
Use the arrow buttons (▲or ▼) to increase or decrease the set temperature. Each press of either button
increases or decreases the value by 1 °C (or 1 °F) to a maximum of 30 °C (or 86 °F) and to a minimum of
16°C (or 61 °F). Holding either button down for more than 2 seconds will cause the degrees to scroll up or
down more quickly. Once the temperature setting is complete, the temperature indicator on the indoor unit
will adjust to reect the change.
NOTE: To prevent cold air from being blown into the room as Heating mode is started, the indoor
unit will delay blowing air for 1 to 5 minutes in order to preheat the air (the actual delay time depends on
indoor ambient temperature).
X-FAN FUNCTION
Allows the fan of the indoor unit will blow air to eliminate moisture on the evaporator to avoid mould formation.
While in Cooling or Drying mode, hold down the FAN button ( ) for at least 2 seconds to activate the X-Fan
function. The symbol " " will appear on the display screen of the remote control.
If the unit is powered down while X-Fan is still running, the indoor fan will continue operation for a few
minutes in order to dry the inside of the indoor unit. Powering up the unit during this time will automatically
deactivate the function.
If the unit has been left running with the X-Fan function activated, hold down the FAN button ( ) for at least
2 seconds to deactivate it.
NOTE: This function is not available in Auto, Ventilation or Heating mode.
FAN SPEED SETTING
Allows the user to select a fan speed in accordance with their needs.

By pressing the button in rapid succession of less than 2 seconds, the setting options cycle through in the
following order:
NOTE: Some angle options are only available for certain models.
When the parameter switches from " OFF " to " ", if you delay pressing the button for more than 2 sec-
onds, the parameter will automatically revert to the " OFF " state.
Holding the button down continuously for more than 2 seconds will cause the airow deectors and louvers
