7.4 About Test Run

are The following procedures describe the test run of the
whole system. This operation checks and determines the
following items:
Check if there is a wiring error (with the
communication check of the indoor unit).
Check if the stop valve is open.
Determine the length of the pipe.
INFORMATION
i
Before you start the compressor, it may take
10 minutes to achieve a uniform cooling
state.
During the test run, the sound of the cooling
mode in operation or the solenoid valve may
become louder, and there may be changes in
the displayed indicators. This is not a
malfunction.

7.5 Test Run Implementation

1. Make sure all the settings you need to configure are
completed. See section 6.2 on the implementation of the
field settings.
2. Turn on the power supply of the outdoor unit and the
indoor units.
INFORMATION
i
Make sure the power supply is turned on 12
hours before operations so that the crankcase
heater is properly energized. This is also to
protect the compressor.
Specific procedures for the test run are as follows:
Step 1: Power on
Cover the lower panel of the ODU, and power on all
IDUs and ODUs.
Step 2: Enter commissioning mode
When the ODU is first powered on, it displays "-. -. -. -."
, which means the unit is not commissioned.
Long press the "DOWN"
simultaneously for 5s on the master ODU to enter
commissioning mode.
Step 3: Set the number of IDUs in a system
The digital display of the master ODU displays "01 01",
where 1st and 2nd digits always on, 3rd and 4th digits
flashing. The 3rd and 4th digits represent the number
of IDUs, the initial value is 1, short press the "DOWN"
or "UP" button to change the number.
Once the number of IDUs has been set, short press the
"OK" button to confirm and automatically proceed to the
next step.
Step 4: Select the system communication protocol
Enter the communication protocol setting interface, the
digital display of master ODU displays "02 0", where
the 1st and 2nd digits always on, the 3rd digit off, the
4th digit flashing. The 4th digit of the digital display
represents the communication protocol type, the initial
value is 0. Short press the "DOWN" or "UP" button to
change the communication protocol.
and "UP" buttons
54
If the system is all SDV6 IDUs, and the IDUs and ODUs
connected by PQ comm., please select SDV6
protocol RS-485 (P Q) communication, and set the 4th
digit of the master ODU digital display to 0; ODU factory
default SDV6 protocol RS-485 (P Q) communication.
If the system has a non-SDV6 IDUs, and the IDUs
and ODUs are connected by PQE comm., please
select the non-SDV6 protocol RS-485
communication and set the 4th digit of the master ODU
digital display to 1.
If the system is all SDV6 IDUs, the IDUS and ODUs are
connected by M1M2 communication, and all IDUs are
powered uniformly, please select the HyperLink (M1M2)
communication + indoor unit uniform power supply, and
set the 4th digit of the master ODU digital display to 2.
If the system is all SDV6 IDUs, the IDUS and ODUs are
connected by M1M2 communication, and there is
separate power supply for IDUS, please select the
HyperLink (M1M2) communication + indoor unit separate
power supply, and set the 4th digit of the master ODU
digital display to 3.
Once the communication protocol has been set, short
press the "OK" button to confirm and automatically
proceed to the next step.
Step 5: IDUs and ODUs address setting
Enter the auto addressing function, the digital display of
master ODU flashes "AU Ad" and "X YZ" in rotation. "AU
Ad" means the auto addressing is in progress, "X"
represents the address of the ODU, "YZ" represents the
number of detected IDUs; the auto addressing takes
about 5-7 minutes, and automatically proceed to the next
step after completion.
Step 6: System initialization
Entering system initialization, the digital display of master
ODU flashes "INIt" and "X YZ" in rotation. "INIt" means
initialization is in progress, "X" represents the address of
the ODU, "YZ" represents the number of detected IDUs;
the system initialization takes about 3-5 minutes, and
automatically proceed to the next step after completion.
Step 7: Test run
During a test run, the system automatically diagnoses the
air outlet static pressure of the ODU, the stop valve
status, the consistency of the refrigerant piping and
communication wiring, and the installation environment.
For a properly installed and connected system, the test
run will last for about 40 to 60 minutes. In this process,
the ODU digital display will show "STP1" to "STP7". After
the test run, the digital display will show "End", 10
seconds after which the system will automatically
proceed to the next step.
In case of an abnormal shutdown of the ODU during the
test run, the digital display will show the error code.
Please troubleshoot according to the troubleshooting
guide. After troubleshooting, the test run will restart
through the menu "n11-2" on the master unit until the
digital display shows "End" and the system proceeds to
the next step. Then, the test run is completed.
Step 8: Complete
Upon completion of the test run, the system will enter the
standby mode, and the digital display will show "X YZ"
where X represents the ODU address and YZ represents
the number of IDU(s) detected. Then, the unit can start
properly.
