Requirements of remote
controller installation site
Do not install the remote controller in a place
exposed to sunlight or outside air (near a
window or the like).
The temperature sensor is embedded both
in the remote controller and the indoor unit.
Switch between them for use.
(When delivery, the indoor unit temperature
sensor is used by default.)
When switching to the remote controller
temperature sensor, please follow the
instructions below to ensure that the sensor
can detect the average room temperature. If
not, it is recommended to use the sensor in the
indoor unit.
• Install the remote controller at a place
3.3 - 4.9ft (1-1.5 meters) above the ground.
• Do not install the remote controller behind
any obstacles where it cannot detect the
room temperature.
• Install the remote controller only in a room
that uses air conditioner.
• Install the remote controller vertically on the
wall or the like.
• Do not install the remote controller at a
place where it will be exposed to the direct
discharge air from the air conditioner.
• Do not install the remote controller on the
wall whose temperature greatly di󰀨ers from
room temperature.
How to wire the remote controller
■Wiring Diagrams
Since the remote controller cable has no
polarity, that’s ok if the indoor unit's terminal A
and terminal B are inversely connected
• Use non-polarity 2-core cable. W：White
B：Black
• Use AWG20 - AWG16
(0.5mm2-1.5mm2) cable.
Cable connection
Please use the attached wire connector to
connect the remote controller cable to the
indoor unit terminal board cable.
If crimping tools are not available, please use
other reliable methods for connection. Do
not only use the insulating tape to connect;
otherwise it can be dangerous.

1. Insert a slot-type screwdriver or the like into
the groove on the lower side of the remote
controller body, and twist it to remove the
rear cover.
2. Cut the plastic stud in the accessory to a
suitable length for lling the gap between
the rear cover of the remote controller and
the studs of the bottom case, and then use
the M4 screws in the accessory to x the
rear cover to the bottom case through the
stud.
Note 1: Do not tighten the screws too
tightly, otherwise the rear cover will deform.
Note 2: When using studs to ll the gap,
make sure that the rear cover height is
uniform to prevent deformation.
3. Connect the remote controller cable (2-
core) to the cable of the remote controller
body. Conrm the terminal number of
indoor unit and connect the remote
controller cable correctly. (The remote
controller may be damaged if connecting
the power supply of indoor unit.)
4. Hang the remote controller body to the
hook on the rear cover and x it in place.
Note 3: Allow at least 1.2in (30 mm) of
space around the remote control.
DIP switch setup
The dial switch is located on the circuit board
of remote controller. When switching, remove
the rear cover. But be sure to turn o󰀨 the air
conditioner power rst.

Multiple remote controller
installation requirements
In a dual remote controller system, one or
more units are operated by multiple remote
controller.
■How to install
For a dual remote controller system, install the
remote controller as follows:
1. Set one of the remote controllers as the
main remote controller. (The default setting
is “Main Remote Controller.”)
2. Slide the DIP switch 1 on the remote
control ler circuit board to the ON position
to set the other remote controller as the
sub remote controller.
■Basic circuit diagram
• Use the remote controllers installed in two
di󰀨 erent locations to operate the same
indoor unit.
• Use the remote controllers installed in two
di󰀨 erent locations to centrally control multiple
indoor units.
* The main remote controller and sub
remote controller both can work in case of
connecting to any indoor unit.

Switching of temperature sensor
Both the remote controller and the indoor unit
have built-in temperature sensors, and the two
sensors cannot work at the same time.
The temperature sensor in the indoor unit is
the default sensor.
If to switch to the temperature sensor in the
remote controller, slide dial switch 4 on the
remote controller circuit board to the ON position.
Note 1: On the main remote controller, you can
switch to the sensor in the remote controller. (If
the remote controller is a sub remote controller,
it is unable to switch.)
Note 2: When using a separately sold remote
controller sensor, set the sensor inside the
remote controller to OFF.
Requirements
When using the remote controller for the rst
time, the initial operation after power on will
last for a while. This is not a fault.
<Initial turn on time>
Let the remote controller run for about 5 minutes.
<Turn on time after the second turn on>
Let the remote controller run for about 1 minute.
The address setting of the multi-split air
conditioners cannot be completed just by
turning on the power (“SETTING” always
ashes). You must perform the operation on
the outdoor interface circuit board to complete
the address setting. The remote controller
cannot be operated when setting the address.
It takes at most 10 minutes to set the address.
Remote controller test run setup
1. Press the ON/OFF button.
Turn o󰀨 the air conditioner.
2. Press the timer o󰀨 button and the “ △”
set button at the same time for at least 10
seconds. The LCD display area shows
“TEST” and becomes test mode.
3. The test run shall be performed in heating
or cooling mode.
• During test run, “TEST” is displayed on
the LCD display.
• When “TEST” is displayed, the
temperature cannot be adjusted.
• During test run, the machine will bear
a considerable load; therefore, it is
advisable not to carry out a test run
unless necessary.
Note 1: After power up, the outdoor unit will not
work within about 3 minutes; otherwise
the operation will stop.
4. After exiting the test run mode, press
the timer o󰀨 button again to ensure that
“TEST” on the LCD display disappears.(The
remote controller has a 60-minute timer o󰀨
function to prevent continuous test run.)
Remote controller DN setting
1. Press the On/O󰀨 button to shut down the
air conditioner.
2.
Hold down the menu button and the “ ▽”
setting button for at least 10s. The LCD
displays “SETTING” and the lower left
corner displays indoor unit address, e.g. 1-1.
After verifying the address, press the timer
o󰀨 button to access the DN setting mode.
3. After accessing the DN setting mode, use
the menu keys to switch between DN code
and data. Flashing means editable state.
Use “ △” and “ ▽” for setting. After this
is done, use the timer o󰀨 button to save
the setting (this step is required for each
setting). After the setting is over, press the
On/O󰀨 button to exit the DN setting mode.
Note 1: When in the DN setting mode, the fan
of the indoor unit will start working.
Before this, please make sure there
is no foreign matter around the fan
blades that may obstruct their normal
rotation and be cautious.
Remote controller state
monitoring mode
1. Hold down the menu button for 10s (in
either on or o󰀨 state) to access the remote
controller state monitoring mode.
2. After verifying the address, press the timer
o󰀨 button to access the state monitoring
mode. Use “ △” and “ ▽”to select the
code to check data.
• Refer to the Installation Manual supplied
with the indoor unit or outdoor unit or
service manual for details about the
check code and data.
3. Press the On/O󰀨 button to return to the
normal display interface.
