Advanced Field Equipment Controllers (FACs)

Featuring Real-Time Clocks for Enhanced Monitoring & Control

Our FAC Series Advanced Field Equipment Controllers feature a real-time clock and support time-based tasks – enabling them to monitor and control schedules, calendars, alarms, and trends – typically for air handling and central plant equipment. FACs feature the ability to continue time-based control and monitoring when offline for extended periods of time, and they can operate as stand-alone controllers in applications that do not require a networked supervisory device or for network applications where it is preferred to have the scheduling, alarming, and trending performed locally.

Features and Benefits
  • Switchable communications protocols from BACnet MS/TP to N2 protocols or N2 to BACnet MS/TP protocols.
  • Standard BACnet Protocol – Provides interoperability with other 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.
  • ZFR Wireless Field Controller (FC)/Sensor/Actuator (SA) Bus Interface – Provides a wireless alternative to hard-wired Metasys system counterparts, providing application flexibility and mobility with minimal disruption to building occupants.
  • Bluetooth® Wireless Commissioning Interface – Provides an easy-to-use connection to the configuration and commissioning tool.
  • 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.
  • BACnet Testing Laboratories™ (BTL) Listing – Ensures interoperability with other BTL-listed devices. BTL is a third-party agency which validates that BAS vendor products meet the BACnet industry-standard protocol.
  • 32-bit microprocessor ensures optimum performance and meets industry specifications.
  • BACnet Automatic Discovery support enables easy controller integration into Metasys BAS.
  • Integral end-of-line (EOL) switch enables field controller as a terminating device on the communications bus.
  • Pluggable communications bus and supply power terminal blocks expedite installation and troubleshooting.
  • Wireless capabilities via a ZFR1800 Series Wireless Field Bus System enable wireless mesh connectivity to supervisory controllers, facilitating easy initial location and relocation.
  • Patented proportional adaptive control (P-Adaptive) and Pattern Recognition Adaptive Control (PRAC) technologies provide continuous loop tuning.
  • Writable flash memory allows standard or customized applications to be downloaded from the Controller Configuration Tool (CCT) and enables persistent application data.
  • Large product family provides a wide range of point mix to meet application requirements and allows for the addition of one or more IOMs and/or Network Sensors to provide even more I/O capacity.
    Support for the DIS17 remote display for monitoring and commanding of I/O and configuration parameters.

When school officials at Central Bucks School District wanted to trim budgets, they insisted that nothing compromise the learning environment. Through a performance contract with Johnson Controls, school officials say they already are saving $1.5-2M in utility costs annually.
