Introduction to FX15
Figure 1: FX15 Classic
The FX15 is a high performance field controller of the Facility Explorer
system, specifically designed for commercial Heating, Ventilating, Air
Conditioning, and Refrigeration (HVACR) applications such as chillers
and rooftops, indoor packaged air conditioning units, air handling units,
and close control units.
The controller has 27 physical inputs and outputs and supports a wide
range of temperature sensors and actuating devices. Additional physical
inputs and outputs may be achieved by adding the XT/XP expansion
modules on the local Extension bus.
The FX15 controller is fully programmable or configurable, using the
FX Tools Pro software package, for a wide range of commercial
environmental control applications.
The FX15 controller is also available with a serial communication card
for integration into a Building Automation System with a LONWORKS®
or N2 Open bus network.
For stand-alone applications an on-board, real-time clock circuit is also
included to support the start-stop scheduling of equipment and real-time
based control sequences.
The FX15 can be integrated, as a slave device, in a distributed control
application managed by a master controller (FX16 Master Controller or
Master Display).
Optional accessories make the FX15 controller the state of the art
solution for the HVACR market:
• N2 Open, plug-in communication card
• LON, plug-in communication card
• user interface: Medium User Interface (MUI) and Large User
Interface (LUI)
