FX15 Controller Technical Bulletin
Operation
Introduction
The FX15 controller is a high-performance field controller and has been
designed to respond to a wide range of applications, including dual
compressor chillers and rooftops, close control units, packaged air
handling units, unit vents, and water source heat pumps.
The FX15 controller has 27 physical input/output points on board and
can be further expanded by connecting the XT91D00/XP91Dxx Series
expansion modules.
Parameters in the control application can be displayed and modified
from the optional user interface.
Key Concepts
Software Programming and Application Configuration
The FX15 controller provides configurable control algorithm, memory
and connectivity services, real-time functions, and I/O expansion
through its customizable, object- and service-oriented architecture. The
device configurations can be created and downloaded into the target
controllers via the FX Tools Pro software package.
The tools available in the package are:
• FX Builder: The programming and configuration of the Facility
Explorer controllers is done using the menus, navigation trees, and
graphic screens of the FX Builder tool. The configuration includes
the definition of the controllers to be connected, the physical inputs
and outputs and data points to be monitored, and the format of the
display screen of the controller.
• FX Builder Express: A simplified version of the FX Builder, called
FX Builder Express, is also available to configure a library of
standard applications specifically designed for Facility Explorer
controllers. The configuration is done using the specific graphic user
interfaces of the FX Builder Express.
