1. Features
1.1 Energy Saving Technology
Innovation technique for full DC inverter compressor
High-performance, low-sound DC inverter compressor operates at a faster frequency, reducing start-up
time. This helps the unit to bring the room temperature up to the set level quickly.
Large capacity DC inverter compressor
The products adopts larger capacity DC compressor, so the piping system can be simple, the wielding
points can be less, and the possibility of leakage can below.

Optimized designed heat exchanger.
Double C-shape heat exchanger combined, large heat exchange area
and high performance, enhance the efficiency of the system.
Compact structure and space saving.
1.2 Convenience And Comfort
Wide operation range
No matter the ambient temperature is as high as 52℃in hot summer or -20℃in cold winter, the system
can operate perfectly and supply comfortable environment for users.
Wide operation voltage range
Normally the voltage divination of the power supply is around ±10%, ARV Individual Series can operate
within ±15%. Especially in the place with unstable power supply, it is useful and effective.
Auto addressing
The outdoor units can send address to all the indoor units in the system
automatically, more convenient and saving the installation time.
The outdoor unit can monitor connected indoor unit quantity in real time
and stop for protection automatically when an error occurs.

Non-polarity communication
2-core shielded signal wire and non-polarity communication between outdoor and indoor unit, easy
installation and make the system more reliable.
Extend pipe length and height
Thanks to DC inverter control technology, it is possible to design a system
with longer piping length and higher level difference, makes the system more
flexible and suitable for most types of buildings.
Max. total piping length----------------------------------------1000m
Max. actual piping length---------------------------------------190m
Max. level difference between IDU~IDU---------------------30m
Max. level difference between ODU~IDU--------------------90m
Max. piping length from 1st branch to the farthest IDU---90m
Different operation modes
Differentoperation mode for various applications. Users can change the mode through the switch on the
outdoor PCB, which is easy operation.
Heating priority: System will work in heating mode only.Other mode demand will no response
Cooling priority: System will work in cooling mode only.Other mode demand will no response
First on priority: The first start indoor unit operation mode will decide system operation, others different
demand will no response.
Majority priority: System operation mode is decided by majoritydemand.
Silent operation
By using optimized fan blades and the computational
Fluid Dynamics technology, the product is equipped with
the night low-noise operation function. Provide more
quiet operation during the night. Minimum operation
noise only 45dB(A)

Night silent operation ( Compare with normal operation, silent operation noise reduce 12dB(A)）
VIP design
Special VIP control function, the VIP room will
decide the whole system operation mode, prior to
the other mode or economic locking function, ensure
the priority of the important room.
Intelligent defrosting
AUX intelligent defrosting technique extend the
heating operation and decrease the frequency of
defrosting. Result in stable room temperature,
offer comfort life.
1.3 Reliable & Stable
Black box function
The E-rom of the controller can memorize the
operation information 30 minutes before the
malfunction happening. It is useful for engineer on
job site, it can be used as instruction for trouble
shooting.

All-around Black box function
The product have some safety protection design as following.
Discharge temperature protection
High/low pressure protection
Drive module protection
Phase sequence protection
Refrigerant lack protection
Four-way valve protection
Indoor unit quantity decreasing alarm function
Compressor over-current protection
1.4 Intelligent Control
Self-diagnosis software
Self-diagnosis software canmonitor the running state of the outdoor and indoor units real time, and
display the malfunction, which is convenient for commissioning and troubleshooting.
Network control
AUX has the independent central control software which can control up to 99 outdoor unit and 1024
indoor unit.
The central control software can be combined with the BMS adapter ,such asBACnet and Modbus
adapter.
