1. General Information (Features)

Johnson Controls proudly introduces new Variable Refrigerant Flow (VRF) air conditioners, a highly-efficient
and reliable air-conditioning system. Recently, increased numbers of buildings are requiring "Intelligent"
facilities that include communication networks, office automation, and a comfortable environment. In
particular, a comfortable environment is becoming more of a year-around requirement in office 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 office buildings.
■ VRF System
Johnson Controls has developed the VRF system with its customers in mind.
This system, which is unique in the world, allows the interconnection of indoor units for all our VRF air
conditioners.
This system provides the consumer with greater flexibility for installation, which means that the air-
conditioning systems will integrate better within complex facility structures.
■ Comfortable Air Conditioning Environment
Fresh air intake is realized while suppressing the air conditioning load by cooling or heating outdoor air.
■ Two Control Mode
Depend on the installation environment and the purpose of use, the DOAS control system can be chosen
from two options.
< Indoor Temperature Control >
In this mode, the control system bring the room atmosphere temperature closer to the set point
temperature of the wired controller, using a temperature sensor (remote sensor or thermistor in the
wired controller) mounted in the room.
[Advantage]
When using an indoor temperature sensor, the system will be able to control the temperature in
collaboration with other indoor units.
