test conditions: indoor 20℃DB, outdoor 7℃DB/6 ℃WB; connection pipe length: 5 m,
without height drop between units.
③The total capacity of connected indoor units must be in the range of 50%~135% of the outdoor
unit capacity. The relevant parameters can be corrected by referring to the unit capacity
correction table.

④The above parameters are tested based on the standard connection pipe length. In the actual
project, the parameters should be corrected referring to the capacity correction for the long
connection pipe of units.
⑤Specifications may be changed due to product improvement. Please refer to nameplates of the
units.

Chapter 2 Commissioning
WARNING!
Before performing operations (such as commissioning, maintenance, and repair) on the device, you
need to shut down the unit and cut off the power, and use a relevant instrument to ensure that the
voltage at the power input terminal is zero, and the power indicator on the main board is off. Otherwise,
an electric shock or injury may be caused.
NOTE!
The unit features a low-power standby function. When the unit is standby, the power indicators on
the main control board and the drive board are on.

2 Safety Requirements
WARNING!
Safety measures must be taken for outdoor operations. All involved commissioning personnel and
maintenance personnel must master the building construction safety regulations and strictly follow them.
Special workers like refrigeration workers, electricians, and welders must hold special work licenses
and cannot work on other posts.
When the device is operated, the power of the entire system must be cut off, and the equipment
safety requirements must be strictly followed.
All installation and maintenance operations must comply with the product design requirements and
national and local safety requirements.
It is strictly forbidden to directly connect the compressor to the power.

3.2 Debugging and Operation
3.2.1 Precautions
(1) Do set one (only one) module as the main module during debugging.
(2) When there is no special requirement, the other functions do not need to be set, and it can be
operated according to the factory settings. For special functions, please refer to the related technical
documents.
(3) Installation and debugging operation must comply with the relevant regulations of the local country
or region.
(4) Debugging must be carried out by a professional or under the guidance of a professional. Do not
debug the air conditioning unit by yourself.
(5) All scattered objects, especially metal chips, wire ends and clamps, should be removed from the
body.
(6) Check if the terminals of the electrical components in the unit are loose and the phase sequence is
correct.
(7) Before debugging, all pipeline valves of the unit are required to be open.
(8) Power cannot be supplied until all installation work is completed.
(9) Before conducting the debugging, please ensure that the compressor has been preheated for more
than 2 hours, and check whether the preheating is normal by hand. Debugging can be started up
only when the preheating is normal, otherwise the compressor may be damaged.
(10)When starting up the debugging, the system automatically selects the operating mode according to
the current ambient temperature.
(11)When debugging, the front panel of the outdoor unit must be completely closed, otherwise it will
affect the accuracy of debugging (as shown in the figure as below).

Short press: press the button for 3s and then release it;
Hold the button for 5s: press the button for 5-10s and then release it;
Hold the button for 10s: press the button for 10s and then release it.
3.2.2 Basic Introduction for Engineering Debugging
3.2.2.1 Debugging Method
DC inverter multi VRF unit has three debugging methods at present:
(1) Conduct it by pressing the buttons on the main board of outdoor unit.
(2) Install proprietary software to conduct the debugging through PC. Indoor and outdoor units’
parameters displayed simultaneously through PC software.
(3) Use multi-functional debugger. (As for the detailed operation method for debugging, please
refer to corresponding instruction manual.)
3.2.2.2 Basic Operations
Operation Action Remarks
Commissioning start Press and hold the SW3 confirm button on
the master unit for over 5 seconds.
—
Selection of
non-wired-controller
commissioning
mode
During the commissioning, press and hold
the SW1 up button and SW4 back button
for over 5 seconds to enter
non-wired-controller commissioning mode.
After entering this mode, the system no
longer detects the communication status
between the indoor unit and the wired
controller, and the indoor unit can be
commissioned without a wired controller.
Commissioning exit
In commissioning status, press and hold
the SW3 confirm button on the master
module for over 5 seconds to exit
commissioning.
—
Commissioning
pause
During commissioning, press the SW4 back
button on the master unit to keep the status
of the completed previous commissioning
phase of the current phase.
For example, if the system receives a
commissioning pause signal when
performing step 10 "Main pipeline status
detection before startup", the system returns
to the waiting phase after step 9 "Refrigerant
detection before startup”.
Commissioning
resume
In commissioning pause status, press the
SW4 back button on the master unit to
continue to perform commissioning. —
