VRF Air Conditioners

Johnson Controls proudly introduces new Variable Refrigerant Flow (VRF) air conditioners, a highly-efcient

and reliable air-conditioning system. Recently, increased numbers of buildings are requiring "intelligent"

facilities that include communication networks, ofce automation, and a comfortable environment. In

particular, a comfortable environment is becoming more of a year-around requirement in ofce buildings.

The VRF multi-split system air conditioner meets these requirements. The proven combination of the scroll

compressor and inverter provides the best air conditioning for small and medium ofce buildings.

■ VRF System

Johnson Controls has developed the VRF system with its customers in mind.

This system, allows the interconnection of indoor units for all our VRF air conditioners.

This system provides the consumer with greater exibility for installation, which means that the air-

conditioning systems will integrate better within complex facility structures.

TC-17006-rev.1

● Easy Maintenance and Flexible Design

(1) Face panel

The unit has been designed with a face panel and a slim body. The front panel is easy to clean and

should remain relatively dust free. It is easily removed and washed with water.

(2) Compact design width of 31-1/8 inches (790mm) (Only for TIWM006B21S and TIWM008B21S)

The compact design width of 31-1/8 inches (790mm) makes it possible to install in a narrow space.

(3) Applicable to centralized control

When each indoor unit is controlled with a wireless controller, there is no need to install a wired

controller with a centralized control system.

● Easy Installation

(1) DIP switch setting without removing the front panel

Other switch settings can be performed without removing the front panel.

Open the electrical box cover and perform the eld electrical wiring work without removing the front

panel.

(2) Operation control with wireless controller

Each unit can be controlled with a wireless controller by

built-in receiver kit. A wired controller is also available

instead of a wireless operation.

A signal-receiving buzzer and indicator light signals the

wireless controller operation.

In an instance of group control with a wireless controller

(multiple units are controlled simultaneously with one

wireless controller), an optional receiver kit or wired

controller is required.
