FEC26 Field Equipment Controllers Installation Instructions
MS-FEC2611-x, MS-FEC2621-x, MS-FEC2611-x OET,
Application
The FEC26 controllers are part of the Metasys® system
Field Equipment Controller (FEC) family. The FEC2511
is a modification of the FEC26 controllers. These
controllers run pre-engineered and user-programmed
applications and provide the inputs and outputs required
to monitor and control a wide variety of HVAC equipment.
The FEC controllers operate on an RS-485 BACnet®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Application Specific Controllers (B-ASCs) and integrate
into Johnson Controls® and third-party BACnet systems.
The FEC26 controller is available with or without an
integral LCD and push button user interface.
Switchable Communications
Protocols
By default, the Metasys system FEC family controllers
and network sensors communicate using the standard
BACnet® protocol, based on the ANSI/ASHRAE
135-2004.
The BACnet protocol is a standard for ANSI, ASHRAE,
and the International Standards Organization (ISO) for
building controls.
FEC, IOM, and VMA16 controllers are BTL- tested and
listed as BACnet Application Specific Controllers
(B-ASCs). FAC field controllers are BTL-listed as BACnet
Advanced Application Controllers (B-AACs). The NS
Series Sensors are BTL-listed as BACnet Smart Sensors
(B-SSs).
Release 10.1 of CCT and later can be used to switch the
Field Bus communications protocol in FEC Family Field
Controllers to be either the standard BACnet
Master-Slave/Token-Passing (MS/TP) or the N2 protocol.
BACnet MS/TP is the default communications protocol
for all new controllers. Switchable communications
protocols provide a cost-effective upgrade and
modernization path for customers with existing N2
controllers. The Modernization Guide for Legacy N2
Controllers (LIT-12012005) and the controller-specific
documentation provide installation and commissioning
support and include tips for efficient and safe
replacement. Refer to the N2 Compatibility Options
chapter of the Controller Tool Help (LIT-12011147) for
information about mapping N2 Objects in controllers with
switchable communications protocols.
