Verasys® Application Controllers


The Verasys® Application Controllers are part of the Smart Equipment Controller family. The Verasys Application Controllers run pre-engineered applications and provide the inputs and outputs required to monitor and control a wide variety of HVAC equipment.

Verasys Application Controllers operate on an RS-485 BACnet® MS/TP Bus as BACnet Advanced Application Controllers (B-AACs). The controllers integrate into Johnson Controls® and third-party BACnet systems.

Verasys Application Controllers include an integral real-time clock that enables the controllers to monitor and control schedules, calendars, and trends. The controllers can operate for extended periods of time as stand-alone controllers when they are disconnected from the system network.


  • Standard BACnet Protocol —Provides interoperability with other Building Automation Systems (BAS) products that use the widely accepted BACnet standard.
  • Standard Software and Application Development —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.
  • Configurable Controller —Eliminates the need for software or programming in the field. Factory commission and programmed. Only configuration of parameters in the field through local display or MAP.
  • Real-time Switchable communication protocols from BACnet MS/TP to Modbus or N2 —Is available through the onboard display or MAP Gateway one configuration parameter can be set to switch the protocol in real time.
  • Dedicated Modbus Integration bus —Provides interoperability with other Modbus devices through the dedicated Modbus master port.
  • Predefined alarms and trends —Based on HVAC/R application all alarms and trends will be predefined within the controller.
  • Auto-Tuned Control Loops —Reduce commissioning time, eliminate change-of-season re-commissioning, and reduce wear and tear on mechanical devices.
  • Universal Inputs, Configurable Outputs, and Point Expansion Modules —Allow multiple signal options to provide input/output flexibility.
  • USB Port —Onboard USB port for firmware upgrades and backup/restore of configuration of the controller.
  • BACnet Testing Laboratories (BTL) Listing —Ensures interoperability with other BTL rev 12- listed devices. BTL is a third-party agency, which validates that BAS vendor products meet the BACnet industry-standard protocol.
