1.4 Product features
DC inverter technology, high energy efficiency, higher EER A+, energy saving for the
user
The outdoor unit adopts DC inverter compressor and motor, so save power energy is just to save
you have already installed the air conditioner, if you want to add or reduce one unit, go ahead freely
as long as your operation complies with our design. Greatly convenient for designer and installer.
Precise control, more comfortable and more reliable
The outdoor is equipped with electronic expansion valve, which will control refrigerant flow more
precisely. As a result, the user will feel more comfortable and the unit is more reliable.
Also, the outdoor is with oil segregator, which will keep the compressor working normally and make
oil return more smoothly.
Universal indoor units for multi upgrade series, unitary smart DC inverter and HAIER
DAC split inverter type
The indoor units are universal for the outdoors which belongs to EASY STOCK series. EASY
STOCK is new concept brought by Haier to be convenient for design, sale, operation, and stock
management.
Adopt the much friendlier refrigerant R410a
The air conditioner system adopts the greatly friendly refrigerant R410a, which is protective for the
ozone layer and is good to avoid the earth getting warmer. Benefit for the environment.
High voltage communication, convenient wiring work
Connect indoor and outdoor directly, and there is no communication wire between indoors. Thus
Multiple control types
The indoor unit can be controlled by multiple types: infrared controller, wired controller, central
controller. More choice, more conveniently.
10℃constant temperature control
When leave home temporarily, press 10℃button of remote controller, the indoor temperature won’
t decrease rapidly while be controlled at 10℃. When come back home, press it again, the unit will
be back to normal status and setting temperature.
Auto–restart function (optional)
All indoor units have auto-restart function. When the power supply cut off suddenly, the unit will
automatically recover the previous running mode once the power supply is on.
Self-diagnostic function
In the course of operation, if the failure occurs, the failure code will display on the wired controller or
the wiring work is more convenient. No need to set indoor address.
money for the user. And the outdoor can match with multiple indoor units, up to 5sets. Even when

on the operation panel. Then according to the failure code chart, you can eliminate the failure soon.
Central control function, if connected with a central controller
That is convenient for building management.
Weekly timing function, if connected with a weekly timer
Universal power supply for 50Hz and 60Hz
The multi upgrade series adopts universal power supply for 50Hz and 60Hz, which is convenient for
design. Much wider application.
