Page 9: General Information (Features)
1. General Information (Features) VRF Air Conditioners 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. - Page 10 FEATURES < Outlet Air Temperature Control > In this mode, the control system bring the outlet temperature closer to the setting temperature of the wired controller, using an outlet air thermistor in the unit. [Advantage] When it is set introduce outdoor air, the system enable intake of fresh air without impacting the room temperature.
