  • Standard Protocol with BTL Listing
    Provides interoperability with Johnson Controls and third-party Building Automation System (BAS) products that use the widely accepted BACnet® standard.
  • Standard Hardware and Software Platform
    Uses a common hardware design throughout the family line to support standardized wiring practices and installation workflows. Also uses a common software design to support use of a single tool for control applications, commissioning, and troubleshooting to minimize technical training.
  • State-Based Application Control Logic with Adaptive, Automatically Tuned Control Loops
    Prevents simultaneous heating and cooling, reduces commissioning time, eliminates change-of-season re-commissioning, and reduces wear and tear on mechanical devices.
  • Universal Inputs and Configurable Outputs
    Allow multiple signal options per channel to provide input/output flexibility.
  • Complete Product Family with Modular Components
    Meets any HVAC equipment or building system control requirement using only the needed components.
  • Ability to reside on the FC Bus or SA Bus
    Provides application flexibility
