The Advanced Application Field Equipment Controller (FAC) Series Controllers are BACnet® Advanced Application Controllers (B-AACs) with integral RS-485 Master-Slave/Token-Passing (MS/TP) communications.
FAC Series Controllers feature an integral real-time clock and support time-based tasks, which enables these field controllers to monitor and control schedules, calendars, alarms, and trends. FACs can continue time-based control and monitoring when offline for extended periods of time from a Metasys® system network.
FAC Series Controllers can also 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/or trending performed locally in the field controllers.
The FAC2612 controller features line-voltage relay outputs, making this controller well suited for use in terminal units. The FAC2612-2 model uses a line-voltage power supply, eliminating the need for a 24 VAC transformer in line-voltage applications.
A full range of FAC and Field Equipment Controller (FEC) models combined with the Input/Output Module (IOM) models can be applied to a wide variety of building applications ranging from simple fan coil or heat pump control to advanced central plant management.
All FAC controllers support wireless communications using the ZFR Series accessories.
Refer to the Metasys® System Field Equipment Controllers and Related Products Product Bulletin (LIT-12011042) for product application details.
•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.
•ZigBee™ 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 between Metasys field controllers to WRZ Series Wireless Room Temperature Sensors and 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
