2 Notices for Application
☆The power supply mode of each indoor unit must be unified power supply.
☆Never install the Receiver in a humid place or a place with direct sunlight.
☆Prevent knocking, throwing, frequent disassembly and assembly of the Receiver.
☆Do not operate the wired controller with wet hands.
☆This product is applicable for multi VRF central air conditioners.
☆Pay attention to the following when matching with multiple VRF units:
①When the priority of system mode is master-slave mode, one indoor unit
must be set as master-mode indoor unit (master indoor unit) in a system
network, and the other indoor units are slave indoor units.
②When the priority of system mode is master-slave mode, the system mode
is subject to the operation mode of the master indoor unit. The master indoor
unit can be set to any mode (including automatic mode), and the slave indoor
unit cannot be set to the mode that conflicts with the system mode. When
the master indoor unit changes mode and cause a conflict between the
operation mode of the slave indoor unit and the system operation mode, the
operation mode of the slave indoor unit will automatically changes to the
system operation mode.
③The system mode priority is cooling priority, heating priority, first opening
priority, second opening priority. The indoor unit can be set to any mode
(excluding automatic mode). When the indoor unit operation mode is in

conflict with the system operation mode, the indoor unit will automatically
switch to system mode.
④The priority of the system mode defaults to the master-slave mode, and only
a specific unit has the priority of other system modes.

②The communication wire of the receiver must be selected according to this
manual. Prohibit selecting the communication wire which doesn’t comply
with the requirement of this manual.
3.1.2 Installation Requirements
(1) Never install the receiver in a wet and damp place.
(2) Never install the receiver in a place with direct sunlight.
(3) Never install the receiver in a place near high temperature objects or a
place where the unit might be splashed by water.
(4) Never install the receiver in the position where facing the window, so as
to avoid interference of neighbor’s remote controller with the same model
and cause malfunction.
(5) When installing the receiver, do not block the signal receiving window area
to avoid affecting the receiving of remote control signals.

3.1.3 Wiring Requirements
There are four kinds of wiring methods between the receiver and indoor unit
network:

Wiring instructions:
(1) When the receiver is connected with multi VRF unit, the wiring methods
as shown in Figure 3-3, Figure 3-4, Figure 3-5 and Figure 3-6 can be
adopted, but please pay attention to the follow:
①When one receiver or one receiver and one wired controller control
several indoor units simultaneously, the receiver can connect any
one indoor unit, but the connected indoor unit shall be of the same
indoor unit series and the connected indoor unit shall be in the same
multi VRF system. When it is applied together with the wired
controller, please set the indoor unit quantity of group control in the
wired controller.
②When the receiver controls several indoor units simultaneously, the
settings of all indoor units controlled by it shall be identical.
(2) In the wiring methods as shown in Figure 3-4, Figure 3-6, there can’t be
two receivers simultaneously and only one wired controller and one
receiver are allowable. The wired controller can be set as master or slave
wired controller and the receiver address will switch automatically (no
need to set receiver address manually) according to the wired controller
address (that is master/slave wired controller). The total quantity of
receiver and wired controller can’t exceed two.
(3) The receiver interface is non-polar, but it can’t be connected with heavy
current.

3.2 Installation Method
(1) When the indoor unit is installed well, select an installation position for the
remote signal receiver according to the size of the connection wire and
the installation position of the unit, leaving a groove and buried wire slot
to install the remote signal receiver and bury the connection wires;
(2) Drill holes on the installation wall according to the installation dimension
in the middle of the receiver dimension drawing, and then insert expanded
plastic into each hole;
(3) Bury the connection wire and fix the connection wire with the screw at the
back of the receiver body;
(4) If Junction box is reserved, please fix the receiver body in the Junction
box with screw M4×25. If Junction box is not reserved, please fix the
receiver body directly on the installation position with tapping screw
ST3.5×25 PA and then assemble the cover;
(5) Connect the connection wire to the corresponding position of the unit
where connecting the wired controller to complete the installation.

4.2 Functions
(1) Press “On Off” button to turn on or turn off the unit: when the unit is on, set
temperature is displayed; when the unit is off, set temperature is not
displayed and the power indicator is displayed.
(2) Under normal operation, the temperature display area defaults to display set
temperature, or set humidity, corresponding error code and debugging code.

Receiver JS13
12
When using the remote control to set and display the indoor or outdoor
temperature, the temperature display area will display indoor or outdoor
temperature for 3s and then switch to display the corresponding set
temperature value.
(3) Under normal operation, when the remote control switches the light on or
off, the remote signal receiver will switch between display and black screen.
When the lights are off, they all go out. At this time, when the remote control
signal is received, it will display normally for 3s and then go out. The light is
defaulted to be on after energization.
(4) Temperature value is displayed in Celsius or Fahrenheit and its unit °C or °F
is not displayed.
(5) When the centralized controller has set partial shielding or full shielding
function, if using a remote control to control the receiver, the receiver’s
buzzer will give out an invalid operation sound (the buzzer quickly responds
twice). When the centralized controller has set energy-saving function, if the
temperature set by the remote control exceeds the upper limit or lower limit
temperature, the buzzer will give out an invalid operation sound (the buzzer
responds twice quickly).
5 Display of Error Codes
When error occurs in the system, temperature display window will display error
code. When multiple errors occur simultaneously, it will circularly display error codes.
