4. Character of Products

1) The length of horizontal refrigerant pipe can reach 70m,the total pipe length can reach
100m, the height difference between indoors unit and outdoor unit can reach 30m, the
height difference between indoor units can reach 10m.

2) 1000m super far distance communication between indoor and outdoor units, convenient
control and easy to enlarge the scale of units assembly.

3) Indoor unit can be controlled separately.

4) Equipped with computer-checking interface, conveniently for service work.

5) Far distance sending of refrigerant, and distribute refrigerant intelligently and reasonably
according to the needs of each room, high efficient and energy saving.

6) Display of automatic test of trouble.

7) Healthy negative ion generation function can refresh the air and excite the oxygen,it is optional.

8) The ceiling concealed models move the indoor electronic expansion valve out to

MP3 (electronic expansion valve box), completely avoid the flow sound of EEV,
extremely lower noise, and realize super-silence running in deed.

9) The ceiling concealed models (except AE07\AE24) all have return air box, it will be
set back return air when out of factory. When installation, bottom plate 2 can be
removed and installed on the back, consequently, return air mode has been
transferred to down return air.

10) In order to remain the best running state of indoor unit, control the refrigerant flow
by MP3 (MP2), so as to realize energy saving for every unit and the most
comfortable operation.

11) The units except for convertible model are all wired controller and remote controller

models.If you want a wired control unit or a remote control unit, please inform us ahead of
schedule.

The unit with remote controller is matched with receive display.
The unit with wired controller equipped with wired controller, can make remote operation on
wired controller with remote controller such as YR-H39, but the remote controller is
additionally purchased.
