1.4 Product features
High efficienct, universal outdoor unit
The outdoor unit can match with wall mounted type, duct and cassette type indoor unit. One set
outdoor can match with multiple indoor units, up to 3 sets. Even when 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.
Total indoor load can be up to 135% than the standard match
The total capacity of all indoor units can be 135% more than the mominal cooling capacity, but the
total indoor cooling capacity will not be increased.
Newly designed V- appearance indoor unit
The wall mounted type indoor unit adopts the newly designed V appearance, more fashion, more
beautiful. The unit is designed with the health airflow and sterilize function, which will make the air
more healthy. Also the air blow direction can be set as step or stepless control, much convenient to
control.
Newly designed guarding plate of valve
In order to protect the valve against the dust, the rain or the snow, etc. we add a
guarding plate to the valve.
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.
Adopt the advanced DC inverter technology
The system adopts the advanced DC inverter technology, which can consume less power energy to
realize the equal efficiency, saving money for you.
With air inlet filter, enhance the air quality
The high efficiency filter can collect the dirt and remove the bacterium, which can be installed on the
easy-to-unload place, convenient to be cleaned.
Convenient infrared remote controller
This remote controller YR-H65 can realize the healthy air flow and sterilize function, it is mobile type
appearance, so smart and compact.
And the infrared controller can be equipped with the controller holder, convenient to fix
the remote controller.

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
on the operation panel. Then according to the failure code chart, you can eliminate the failure soon.
Central control function, if connected with a detector and a central controller
That is convenient for building management.
Weekly timing function, if connected with a detector and a weekly timer
Adjustable heating temperature compensation
In heating mode, the temperature compensation can be adjusted by the remote controller. If you do
not want the compensation, you can set the compensation as 0 degree.

The noise level will be measured in the third octave band limited values, using a Real Time Analyser
calibrated sound intensity meter. It is a sound pressure noise level. The detailed method please refer to
the following information:
Installation state: the unit should be placed on the flat floor or be mounted in horizontal direction.
Testing method:
outdoor unit:
1.air outlet from side: the noise level is the average sound pressure level measured from front, left, right
directions.
2.air outlet from top: the noise level is the average sound pressure level measured from front, back, left, right
directions.
measured point:
H ( height to the ground) = (h (unit height) + 1m) /2
