Features
Environment-friendly Refrigerant
Daikin is committed to protecting the global ecosystem and has developed air-cooled chiller with R410A, a new
type of environment-friendly refrigerant. Without chlorine, the environment-friendly R410A causes no harm to the
ozonosphere ( ODP=0).
Easy Installation
UAL R410A series is designed to best facilitate user installation. The refrigerant system is made hermetic in the
factory. Customer do not need to connect any copper pioe or rell refrigerant or invest more money for complex
water systems.
Outstanding Performance
UAL R410A series features leading-edge scroll technology and name-brand accessories which are strictly tested
for high compatibility and reliability. Equipped with efcient scroll compressors and precise electronic expansion
valves, these units feature high EER, especially at partial load.

Flexible module combination
1~10 sets with different capacity can be combined at will to satisfy the load selection requirements of various
applications. The modular design of the unit allows the owner not to have to invest in the equipment at one
time, the owner can increase the investment at any time with the development. The number of modular and the
corresponding equipment greatly save the initial investment.
Compact Size
Moreover, UAL R410A series features compact size. UAL R410A can be lifted without large lifting tools and located
on the roof, balcony or any possible outdoor space.
Reliable Operation
UAL R410A series adopts modular design and one by one start, reducing the impact upon the grid when starting.
All units have undergone strict and long-term test, ensuring relable operation even under extreme cold conditions.
Units themselves, moreover, have multiple pretections. Then security of units is maximally guaranteed.
Low Sound Level
Thanks to the newly designed spiral blades, the outdoor units feature smooth air ow signicantly reducing the
turbulence and lowering the air ow sound level. Unique compressor sound-insulation design and fully hermetic
volute compressor minimizes the operation noise.
Intelligent Control System
UAL R410A features user-friendly intelligent control system. Micro chip and large-scaled LCD display are employed
to make the control swift and easy.
■ Group control (Optional): One single controller can control a group made up by one master unit and maximum 9
slave units.
■ BMS (Optional): UAL R410A provides interfaces for BMS. One serial port can support maximum 32 gateway and
one gateway can support one master unit and maximum 8 center units and one end unit.
Basic operating mode Fault alarm and protection
■ Cooling ■ More than 13 protection and fault alarm functions
■ Indoor controller lock
Parameter setting Memory function
■ Real time setting ■ Backup battery for realtime clock
■ Weekly timing on/off (one on/off per day) ■ Customized parameters preservation after power failure
■ Cooling water inlet temperature
Parameter display Other functions
■ Running status display ■ Error log inquiry
■ Setted inlet water temperature ■ Average compressor worn time
■ Actual inlet water temperature ■ Remote on/off
■ Timing point ■ Water system two-way valve control
NOTE:
■ THE LENGTH OF COMMUNICATION WIRE BETWEEN THE MASTER UNIT AND THE WIRED CONTROLLER IS 40M. THE LENGTH OF
COMMUNICATION WIRE ATTACHED TO THE SLAVE UNIT IS 5M.
■ THE MAIN BOARD OF THE UNIT PROVIDES AN INTERFACE FOR REMOTE CONTROL. BUT REMOTE CONTROLLERS ARE NOT
PROVIDED AND SHOULD BE INSTALLED ON SITE.
