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.

Outdoor temperature(cooling): 35℃DB/24℃WB, outdoor temperature(heating): 7℃DB/6℃WB

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

and, it is 1m to each side.
