3 Introduction to IDU Functions
Indoor unit functions cover user operation functions and engineering application functions. For user
operation functions, refer to wired controller and remote controller.
Engineering application functions can be operated through the IDU wired controller(XK46).
3.1 User Parameter Query
User parameters can be queried in power-on or power-off status.
(1) Press and hold the “FUNCTION” button for five seconds to enter the user parameter query interface.

3.2 User Parameter Settings
User parameters can be set in power-on or power-off status.
(1) Press and hold the “FUNCTION” button for five seconds. The temperature area displays “C00”.
Press and hold the “FUNCTION” button for another five seconds to enter the wired controller
parameter setting interface. The temperature area
displays “P00”.

Remark
After the IDU connected
with the current wired controller is
successfully set to master IDU, "MASTER"
on the wired controller is on.
This setting can only be enabled through the
master wired controller.
When the infrared remote receiving function
of the wired controller is disabled, neither the
master nor slave wired controller can receive
remote signals. The wired controllers can
only be operated by pressing.
When two wired controllers simultaneously
control one IDU, the two wired controllers
should use different addresses. The slave
wired controller (address: 02) does not have
the unit parameter setting function except its
own address settings.
After identifying the IDU type, the wired
controller only displays the available
static pressure levels.

When power supply is insufficient, users are
allowed to power on/off the IDU set with
preferential operation and other IDUs are
forcibly powered off. A fault code is displayed
on the IDU that is forcibly powered off.
Note:
In parameter setting status, "FAN", “TIMER”, "SLEEP", and "SWING" are invalid. By pressing the
“ON/OFF” button, users can return to the main interface but not power on/off the unit.
3.3 Engineering Parameter Query
Engineering parameters can be queried in power-on or power-off status.
Press and hold the “FUNCTION” button for five seconds to enter the engineering parameter query
interface. The temperature area displays “C00” and “View” is on.
(1) Within five seconds after “C00” is displayed, continuously press the “MODE” button for three times in
an interval less than one second to enter engineering parameter query.
(2) Select a parameter code by pressing “ ” or “ ”
Press the “ENTER/CANCEL” button to return to the upper-level menu till quitting parameter query.

2. When there is only one IDU, press the “MODE” button in “nb”
status to enter bar code query without selecting the project

3. The system quits the query status if no operations are
performed in 60 seconds.
4. The bar code query starts from the entire-unit bar code of IDU
and ends at the controller bar code of IDU without circulation. That
is, the query does not start again even if users press “▼”.

In parameter query status, "FAN", “TIMER”, "SLEEP", and "SWING" are invalid. By pressing the
“ON/OFF” button, users can return to the main interface but not power on/off the unit.

3.5 Failure Display
When a fault occurs during the system operation, the temperature area of wired controller displays
the fault code. When multiple faults occur, fault codes are circularly displayed.
When a fault occurs, power off the unit and ask for professional maintenance personnel for help.

4 Monitoring Software
4.1 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.

Duct type split Air conditioner Inverter Series
4.2 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.
