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 nominal 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.

Commercial Air Conditioner
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.
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.
Software for diagnostic installation
After installation, you can use file "X-MULTI Setup Assistant " to know the installation is OK or
not, if system has error, software will give you trouble shooting.
