Intelligent defrosting program Conventional unit's defrosting timing & duration is fixed

Intelligent defrosting program starts according to heat exchanging efficiency & capacity change due to the frost. Less temperature fluctuations, people feel more comfortable.


Benefits For Users06. Fan Reversal Protection

In standby, if the outdoor fan motor is rotating in opposite direction at a high speed by the wind or other natural factors, the unit can’t start so as to keep the fan motor from broken down. It will start when the fan motor speed slow down.


Benefits For Users07. Flexible For All Kinds Of Rooms

8 types & 55 models of indoor units, suitable for all kinds of rooms.


03. Benefits For Installers


Benefits For Installers01. Long Pipe & Height Difference.

The total pipe length: 125 m

The longest pipe length: 50 m

Height deference: 30 m Height difference

between indoor units: 15 m

Length from first indoor distributor to last indoor

unit: 25 m

<25m<50m

<15m<30m


Benefits For Installers02. Space saving installation

Multiple indoor units can be connected to 1 outdoor unit, and long piping connection is also possible.

Compare to one-drive-one type, the outdoor unit can be installed in various places to realize the space-saving installation.


Benefits For Installers03. Addressing Methods

Automatically addressing: system will distribute address to indoor unit automatically

Automatic addressing will reduce artificial faults and manual works.


Benefits For Installers04. Automatic Addressing
