1.General Introduction
1.1 Function Introduction
This smart centralized controller is intended for New UNI DC Inverter Series, capable of controlling
up to 16 sets of units with maximum of 16 indoor units.
Through this smart centralized controller, it is available to view and control those running parameters
of the indoor unit, including on/off, running mode, fan speed etc, and also perform the single control and centralized
control, further, it also can set the weekly timer and long-distance shielding to realize convenient control to the
air conditioning system.
a. Single control: it is intended to control the running parameters of a designated indoor unit individually.
b. Centralized control: it is intended to control the running parameters of all indoor units at the same time.
c. Shielding under single or centralized control: it is intended to shield the running parameter of the indoor
unit.
d. Weekly timer under single or centralized control: it is intended to set when to start/stop the unit through
long-distance control.
e. Clock: it is intended to set and display the weekday, hour and minute.
After the debugging to the controller is nished, it can check the on-line indoor units and display the
parameter setting of the current running mode, set temperature, fan speed, weekly timer, shielding function etc.
When some error occurs, the error symbol and the error code will be displayed to warn a quick maintenance.
This smart centralized controller can be connected to the unit through the communication line without
the need of the communication module, which can extremely ease and simplify the installation.

5.3.5 Timer
Timer, namely weekly timer, taking one week as a cycle, is enabled to set the on/off time (taking 0.5 hour
as the unit) of the unit on some day or days in one week and several time periods at the same day and then
keep this setting circulating weekly.
Introduction to the weekly timer:
a. Once the weekly timer is set, the unit will automatically be turned on/off as the set time starts/ends. For
instance, on condition that the current time is 9:00 Friday and the setting of the timer is shown as the gure
below, then the unit will be turned on at 10:00 and turned off at 10:30 and then again be turned on at 12:30 and
off at 13:30.
b. The weekly timer does not conict with the manual on/off control, that is, the unit can be turned on/
off manually even if the weekly timer is set and the unit also can be turned on/off as the setting of the weekly
timer.
For instance, on condition that the weekly timer is set as the gure below from 8:00 to 10:00 and from
15:30 to 21:30, the current time is 8:40 Friday and the unit is turned off manually, then the unit will be
automatically turned on at 15:30 and later turned off at 21:30.

a. Interface of the Power Supply
① .
The interface CN1 of the power supply module board is for the connection board of the external
power cord, the terminal AC-N for the neutral line, the terminal AC-L for the live line and the middle terminal
keeps open.
② .
The interface CN4 of the power supply module board which is for the power supply of the display
board, is connected with the interface CN1 of the display board through the two-core wire.
b.Communication Interface
The interfaces CN2, CN3, CN4 and CN5 of the display board are for communication, and CN2 namely
COM4 is for the communication o the duct type unit (2-pin).
7.1.3 Preparation and Connection of the Communication Line
a. The communication line between the centralized controller and the unit should be prepared by the user
according to the actual project.
b. Preparation and connection of the communication line.
① .
The communication line is the two-core line (one end is the two-core head and the other end
is the crystal head. (code: 40113325, legth: 1m).
② .
Where there are N sets of units, then N+1 communication lines are needed.
③ .
Connect the two-core head of one communication line to the port COM4 of the smart centralized
controller and connect the two-core heads of N communication lines to the two-pin socket of the wired controller
of the New UNI DC Inverter Series.
④ .
The user can prepare the extension line and connect the wires inside the crystal head according to the
actual need.
Note: one set of New UNI DC Inverter Series consists of one outdoor unit and one indoor unit.
7.1.4 Installation
The installation can proceed on when the installation location is selected and the installation steps are as
follows:
a. Firstly make sure where to install the smart centralized controller.
b. Embed the power supply box (2) as Fig.7.6 for the installation of the bottom case (3).
c. Connect the power cord and the communication line of the display board and then let both go through
the power supply box (2).
d. Fix the bottom case on the power box (2) by screws.
e. Tidy up the power cord and the communication line inside the smart centralized controller.
f. Close the cover (5).

7.2 Unit Matching
Provided New UNI DC Inverter Series unit (one outdoor unit is matched with one indoor unit) is needed
for some project, one smart zone control can control up to 16 indoor units.
Example:
Suppose that there are ve outdoor units and five indoor units for some project, only one Smart centralized
controller is needed.

7.3 Debugging and Viewing the Port No. and the Indoor Unit Address
Debugging setting: In the event that the unit is initially powered on, the setting for the project changes,
or the serial port is replaced, and then it is available to go to the debugging status by pressing “Mode” and
“Thu” simultaneously for ve seconds, under which page, it is enabled to check automatically and distribute
the address of the indoor unit. 10 minutes later, the debugging is nished and the indoor unit which gains the
address is under control and the unaddressed indoor unit is not.
Viewing the serial port and the indoor unit address: It is available to go to the debugging page by pressing
“Mode” and “Thu” simultaneously for ve seconds, under which page it is enabled to view the serial port and
address of the corresponding indoor unit.
Page 37
33
The press on “Conrm/Cancel” can conrm this debugging setting and go to the viewing state of the
current indoor unit; otherwise this setting will not be saved.
See Fig.7.7 for the debugging operation. Fig.7 shows the indoor unit 1 and indoor unit 2, both of which
are connected with the port COM2. The address of one is 01 and the other is 04.
Fig.7.7 Debugging
7.4 Labeling
A label is provided to identify the relationship of the indoor unit No. and the corresponding room name.
The user can write down the indoor unit No. and its corresponding room name on the label which then will
be stuck to the inside of the cover of the smart centralized controller so that the user can be clear about
the control object.
For instance, when the user has installed the air conditioners in the child room, bedroom and living
room, after the debugging it is available to view the indoor unit No. of each room and get clear about their
corresponding relationship.
Page 38

Room Name Child Room Bedroom Living Room
Indoor Unit Address Port 1,Indoor Unit 04 Port 1, Indoor Unit 05 Port 1,Indoor Unit 06
Indoor Unit No. 1 2 3
After get clear about the relationship of the indoor unit no. and the room, the user can write “Child
Room”, “Bedroom”, “Living Room” on the place “1”, “2” and “3” respectively on the label and then stick the
label to the inner side of the smart centralized controller.
See 7.8 for the label:
