cases may cause serious consequences
CAUTION:
: It must be strictly prohibited where marked with Prohibited ,
otherwise may result in machine damages or endanger the user
personal safety.
: It must be strictly followed where marked with To be followed ,
otherwise may result in machine damages or endanger the user
personal safety.
Instructions: This information can ensure correct operation of the machine.
Be sure to follow the following important safety precautions.
These precautions should be at hand to be checked at any time when needed.
If air conditioner is transferred to a new user, this manual should be as well

Brief description on functions
The remote central controller (hereunder as central controller ) is a necessary part at the option of the user for Haier commercial air conditioner remote
monitoring system group control functional network . A remote control monitor(or dector) is used to transform standard digital interface and realize bus code address communication.Connecting the air conditioner directly,it undertakes
local processing and gathering of air conditioner control and operation information,transmitting control and information data to the central controller.A network air conditioner (hereunder as air conditioner ) is defined as an air conditioner having an indoor computer board with remote control interface, only which
could combine with parts such as the monitors and central controller to form a
remote monitoring system
group control network , fulfilling the function of
data exchange and monitoring .
The central controller could consult through the monitors as well as display
through the LCD the main work status of the air conditioner. With it the work
status of main functions of the air conditioner could be set through key input
and LCD display . It can also monitor the basic working status of all air
conditioners in the network . In addition, the central controller is equipped with
a 24 hours real-time clock system for centrally control the clocks in the network .
Brief descriptions are given as follows :
1. Communication function
Communicate with the monitors in the group control network
To communicate with the monitors through the RS-485 bus (A, B). The
central controller sends commands to and receives response from the monitor;
communication by address enables sending and receiving control information,
work information and fault information between the monitors and the central
controller.
2. LCD display function:
The LCD could display the fundamental status of air conditioning units (are
the units existing? On/off? Fault? Are units group selected? Cursor and the
current unit no.);
The LCD can display the working status of the air conditioning unit with the
current number (mode, fan speed, temperature setting, room temperature,timer,
error code, central/remote control status);
The working status of the central controller (monitor/set status, panel locking
status, signaling status).
3. Key input function:
The keys for moving the current unit number cursor and for group selection:
, ,
, , SELECT;
The keys for setting working status of the air conditioning unit and control
conditions: ON/OFF, MODE, FAN SPEED, TEMP TIME
/
, CLOCK,
TIMER, CENTRAL/REMOTE, SET;
The key for locking key function of the central controller: LOCK.
4. Unit number setting function:
To enrich the control functions of Haier commercial air conditioner remote monitoring system, multiple controllers could be set to work together for a combination
of multiple functions. For this, the central controller is provided with a two-digital
switch for setting controller address.

System general information
1. Realizing group control function with the central controller
A monitor is connected with an air conditioner through A+, A- of the 4-wire screw
terminals on the interface for air conditioner, meanwhile the monitor dial switch
shall be set as single unit working mode and the address unit number shall be set
according to the planed scheme, see "Setting of the Dial Switch" for detailed setting
and corresponding addresses. For realizing group control function through the
central controller, the system still needs to connect the monitors. Each monitor shall
be connected with the twin twisted shielded communicating bus through the twowire screw terminals (A, B) on the RS-485 interface. For the communicating bus, it
is required to be shield grounded and the resistances on two sides shall be matched.
2.Realizing double unit switch-over group control function with the central
controller
A monitor is connected with two air conditioners with the same model through the
4-wire screw terminals on the interface for air conditioner, meanwhile the monitor
dial switch shall be set as double unit switch-over working mode with the default
switch-over time of 24 hours, and the address unit number shall be set according to
the planed scheme, see Setting of the Dial Switch
for detailed setting and corresponding addresses. For realizing double unit switch-over group control function
through the central controller, the system still needs to connect the monitors. Each
monitor shall be connected with the twin twisted shielded communicating bus
through the two-wire screw terminals (A, B) on the RS-485 interface. For the communicating bus, it is required to be shield grounded and the resistances on two sides
shall be matched.

3. For some newly-developed models, such as A******BEA, A******BIA,
A******ERA, in indoor PCB , we set the stanard connector data transforma-
tion function of the detector. They can connect the central controller directly
through the RS-485 communication protocol. The detailed information
refers to the operation manual with the unit.
For the above models, have no double unitswitch-over group control function.
If you want the timing function, the weekly timer YCS-A001 is necessary,
and is used together with YCZ-A001. The address seeting of weekly timer
needs to be adjusted, please refer to the operation manual with the unit.
The detailed information refers to the operation manual with the unit.

Installation manual for wire controller
The communication wiring is 4 meter long; if the actual length is more
than it, please distribute wiring according to below table:
2. Communication wiring:
The wired controller is equipped with special communication wiring in the accessories.
3-core terminal (Polar wire) is connected with the terminal A, B, C of wired controller
respectively.
1. Wiring connections of wired controller:
There are three methods to connection wired controller and the indoor units:
A.One wired controller can control max. up to 16 sets of indoor units, and 3 pieces of
polar wire must connect the wired controller and the master unit (the indoor unit
connected with wired controller directly), the others connect with the master unit through
2 pieces of polar wire.
B. One wired controller controls one indoor unit, and the indoor unit connects with
the wired controller through 3 pieces of polar wire.
C. Two wired controllers control one indoor unit. The wired controller connected with
indoor unit is called master one, the other is called slave one. Master wired controller
and indoor unit; master and slave wired controllers are all connected through 3 pieces
of polar wire.
*One side of the shielded sheet of communication wire must be earthed.

3.Setting address method:
The dip switch of indoor unit usually marked with "SW" or "BM", you can refer the
below table to set address:
If you use central controller , the clip switch will be used simultaneously.
Wiring request in central control type: port A-B is connected with indoor port refer to
A-B through 2-core shield wire. Requirements:
1.Port A connects with port A of all indoor units.
2.Port B connects with port B of all indoor units.
Refer to the Figure 3 to wiring.
The address setting can be realized by the dip switch, which used to set address in
indoor PCB. Please refer the indoor unit circuit diagram to find the dip switch.
If you use the group control function, there should be a master unit and 15 sets of
slave units.Refer to the operation manual with the unit to set the master unit or the slave
units.
The indoor PCB is matched with this wired controller (YR-E12)which can be set
according to below table:
When the wired controller controls several indoor units, there is only one Master unit,
and other can be set as Slave unit.
The detailed information manual with the unit to set the master unit or the slave units.
The wired controller must be used with cooperation with indoor unit. When wired control
type is selected, the function of indoor unit must be adjusted (after power cut off).
