New VRF central controllers from Johnson Controls offer more options


MILWAUKEE (March 23, 2016) – A new central controller and enhanced network adapter software from Johnson Controls make it easier than ever to manage variable refrigerant flow (VRF) systems, whether within a building management system or independently.

Users can now easily integrate their VRF systems with a BACnet® or LonWorks® system with enhanced adapters, or can use a remote-access, web-based dedicated system.

The new BACnet adapter software, which can control up to 64 refrigerant systems and 160 indoor units, provides:

  • Web-based interface for configuration
  • Streamlined installation and setup from a familiar web browser
  • Support for Fahrenheit (°F) and Celsius (°C) units
  • 1°F (0.5°C) increments for temperature control
  • Simplified commissioning of indoor units with an auto-discovery function

The new LonWorks adapter provides similar functionality for the LonWorks open protocol.

The new Web-enabled central controller’s Web-based interface allows a VRF system to be controlled and monitored by up to five local or remote Windows-based PCs and/or tablets. Other features include:

  • Built-in software for easy access with no need for an optical drive for installation
  • Advanced multi-zone control of large commercial projects
  • Block and group control for scheduling, mode, setpoint and prohibit-RC functions
