1.2.2 Installation method
Fig 2.6 Installation of Wired Controller
Above is a simple installation method of wired controller. Please pay attention to the following:
(1) Before installation, disconnect power of the indoor unit. Do not operate when power is connected.
(2) Pull out the 2-core twisted pair cable from the installation hole on the wall and lead it through
the hole on the back plate of wired controller.
(3) Place the wired controller on wall and secure its back plate on wall with screw M4X25.
(4) Connect the 2-core twisted pair cable to terminal H1 and terminal H2. Tighten up the screws.
(5) Stick the cable in the slot that is left of the terminals and buckle the wired controller’s panel
with its back plate.
Note:
If caliber of the communication cord is too large, which causes difficulty in leading or sticking the cord
according to above point 2 and point 5, strip some of the sheath of the communication cable to meet
the installation requirement.

3 Monitoring Software
3.1 Function introduction
Integrating with telecommunication technology and computing software, Gree Commissioning Tool
Kits can realize the comprehensive monitor, control and commissioning on central air conditioners. It is
an efficient solution for the management of central air conditioners that are separated in different parts of
a building. Administrator doesn’t need to control every unit on site, but rather controls the units by just
sitting in front of a computer. This will not only improve the productivity, but also reduce cost on human
resources, property and management.
Gree Commissioning Tool Kits can monitor and control the duct type split air conditioner inverter
series. User can monitor and control units by monitoring the computer. This software is an efficient tool
for the intelligent air conditioning management as well as installation and after-sales service and
commissioning. It can debug units and control units’ operation status quickly and conveniently. It will not
only improve the productivity but also reduce the difficulty and cost of commissioning and maintenance,
providing better and faster service to customers.
3.2 Connection of computer and units
It can be connected with single-system network or multi-system network. In the single-system
network, indoor units or outdoor units are connectable, while in the multi-system network, only the master
outdoor unit can be connected.
Seen from the diagram, Gree commissioing network is made up of 3 parts:
The 1st part is the monitoring computer, including Gree debugger and Gree USB converter driver
that are installed in the computer.
The 2nd part is Gree USB converter, which is to convert the air conditioning communication into
computing communication. This part is made up of Gree USB data converter and USB data wire.
The 3rd part is air conditioners, including outdoor units, indoor units and the connection wires. If
connection wire is not long enough, it’s OK to connect via the patching board of the commissioning tool
kits. In a single-system network, both indoor units and outdoor units can be connected, while in a multi-
system network, only the master outdoor unit can be connected.

3.3.2.3 Operation instruction
(1) Power LED:a red light. If the red light is on, it indicates normal power supply. If the red light is
off, it indicates the power supply of converter is not normal.
(2) Communication LEDs:yellow lights. When converter is working and the computer is transmitting
data, the TX data transmitting light will be flickering. When units are uploading data to the
computer, the RX data receiving light will be flickering.
(3) When converter is under RS485 data transferring mode, the function LED of RS485 to USB will
be on.
(4) When converter is under CAN data transferring mode, the function LED of CAN to USB will be
on.
(5) When converter is under HBS data transferring mode, the function LED of HBS to USB will be
on.
(6) USB interface:connect USB data wire.
(7) CAN interface:When converter is under CAN communication mode, connect air conditioner’s
CAN data interface. CAN interface exhibits no polarity (A and B are equal).
(8) HBS interface:When HBS converter is under HBS communication mode, connect air
conditioner’s HBS data interface. HBS interface exhibits no polarity (This interface is not yet
available for Gree debugger and the monitoring software).
(9) RS485 interface:When RS485 converter is under RS485 communication mode, connect air
conditioner’s RS485 data interface. RS485 interface exhibits polarity and terminal A and B are
different.

3.3.2.4 Installation notice
(1) Install indoors.To avoid collision,it is suggested to place it in the monitoring room together with
the computer.
(2) No need of power supply.Power is supplied through computer’s USB interface.
3.3.3 Communication board
Communication board is mainly used for transferring data.It functions similar with a patching board.
Provided that units are far away from the monitoring computer,communication board can be used for
connection.
3.3.4 Communication cord
3.3.4.1 USB wire
Connect USB wire with computer’s USB interface at one end and with the USB interface of USB data
converter at the other end, as indicated below:
3.3.4.2 Board Connection Wire
There are 2 board connection wires supplied for the commissioning tool kits. One is 1 meter’s long
and the other is 5.5 meters’ long. They are only different in length. One end of the wire shall connect with
air conditioner’s communication interface and the other end shall connect with CAN interface of Gree
USB converter. As shown below, the wire can be connected to the communication interface of outdoor
unit or the communication interface of indoor unit:
USB Wire

3.4 Software introduction
(1) One-button commissioning
Personnel responsible for the commissioning of air conditioners can start commissioning by pressing
one button according to the commissioning logic of software, which will give the commissioning order to
units. Then commissioning will be started up automatically step by step. During the commissioning, the
corresponding process will be ticked in green on the software interface. If any commissioning process is
not normal, it will be displayed in red.
(2) Comprehensive monitoring
The software can monitor every part of the air conditioning system, including functions, equipment
and components operating status. The monitoring results will be displayed in text or curve so that user
can acquire the operating status of the entire system conveniently and straightforwardly.
(3) Real-time control
Air conditioner’s operating time and requirements may be different based on areas and functions.
User can set units’ parameters on computer according to actual needs, such as the on/off, temperature,
fan speed, mode, etc. Meanwhile, the software can also set or view the function parameters of outdoor
units, gateway and other equipment. In this way, the mangement of central air conditioners is realized.
(4) Replay history
Software can replay and save the historical monitoring information in the data base. The replay speed
can be selected and the information will be shown in text or curve. This function has greatly saved the
time to track problem cause and resolved the difficulty of problem reproduction.
(5) Applicable to multiple series, models and users
Gree Commissioning Tool Kits is applicable to air conditioning system that comsists of multiple series
and models. Later, it will be developed to cover all series of Gree central air conditioners, such as multi
VRF, centrifugal chiller, screw type chiller, ground source heat pump units, modular units, fan coiled units,
close control units, etc. It can be used by system and controller designers to develop and monitor units,
or used for maintenance and commissioning.
(6) Other functions
For the convenience of users, the software has added functions like connection guide, printing screen,
opening database folder, rebuilding database, changing database saving path, etc.
