Johnson Controls FAC3613 Installation Manual

FAC3613 Advanced Application Field Equipment

Application

The FAC3613 Advanced Application Field Equipment
Controller (FAC) is part of the Metasys® system
Field Equipment Controller family. The FAC36
Series controllers run pre-engineered and user­programmed applications and provides the inputs
and outputs required to monitor and control a wide
variety of HVAC and other facility equipment.

FAC36 controllers operate on an RS-485 BACnet
MS/TP Bus as BACnet Advanced Application
Controllers (B-AACs) and integrate into Johnson
Controls® and third-party BACnet systems.

FAC36 field controllers include an integral real-time
clock, which enables the controllers to monitor
and control schedules, calendars, and trends, and
operate for extended periods of time as stand-alone
controllers when offline from the Metasys system
network.

Communications protocols

The FAC3613 field controllers can communicate
using BACnet MS/TP, N2, or wireless Zigbee. By
default, the FAC3613 field controllers communicate
using the standard BACnet MS/TP protocol. The
BACnet protocol is a standard for ANSI, ASHRAE, and
the International Standards Organization (ISO) for
building controls.

The FEC Family Controllers, including the FAC3613,
can be used as functional replacements for
legacy N2 controllers. The N2-capable MS/TP
field controller models provide a cost-effective
upgrade and modernization path for customers
with existing N2 controllers. For installation and
commissioning support, and tips for efficient and
safe replacement, refer to the Modernization Guide
for Legacy N2 Controllers (LIT-12012005) and the
controller-specific documentation. For information
about mapping N2 Objects in controllers with
switchable communications protocols, refer to the

N2 Compatibility Options chapter of the Controller Tool
Help (LIT-12011147).

To configure FAC3613 field controllers to
communicate using the N2 communications
protocol, see Configuring N2 Communications.

The FAC3613 field controller can also be installed in
a wireless application using a ZFR/ZFR Pro Wireless
Field Bus Router. To configure these controllers to

communicate using the wireless communications
protocol, see Configuring Wireless Communications.

Fast persistence

The FAC3613 model has been significantly upgraded
and now includes a fast persistence feature that
allows you to retain data values at a configurable
interval, up to once per second. Persistence refers
to how often samples of data are stored locally. This
upgrade to the persistence feature ensures that
in the event of a problem, such as a loss of power,
more recent data can be retrieved up to the rate that
the data is persisted, minimizing the potential loss of
data. When power is restored, previously persisted
data, up to the rate of persistence, is still available
and accessible. When persistence is configured
for once per second, you risk losing only the most
recent one second of data before the power loss.
Persisting data may be essential for situations that
require greater data accuracy. This may include
certain methods of utility data collection and billing

Attributes that can be persisted in the FAC3613
include: Counter Input Present Value Attributes,
Binary Input, Binary Output, and Binary Value COS
Counts and Active Time Attributes, and PID/PRAC
tuning parameters.

Terminal blocks and bus ports

See FAC3613 physical features for terminal block
and bus port locations on the FAC3613 controller.
Observe the following guidelines when wiring a
controller.

Input and Output terminal blocks

The fixed input terminal blocks are located on the
bottom of the controller, and the output terminal
blocks are located on the top of the controller. See
Table 2 for more information about I/O terminal
functions, requirements, and ratings.

FC bus terminal block

The FC Bus terminal block is a blue, removable, 4­terminal plug that fits into a board-mounted jack.

Wire the removable FC bus terminal block plugs on
the controller, and other controllers in a daisy-chain
configuration using 3-wire twisted, shielded cable as
shown in Figure 4. For more information about the

Figure 6: Pin number assignments for sensor, SA
bus, and FC bus ports on Field Controllers

Figure 7: 24 VAC supply power terminal block
wiring

SA Bus port

The Sensor (SA Bus) port on the bottom of the
controller is an RJ-12, 6-position modular jack
that provides a connection for MAP Gateway, the
Bluetooth® Commissioning Converter (BTCVT), the
VAV Balancing Tool, specified network sensors, or
other SA Bus devices with RJ-12 plugs.

A DIS1710 Local Controller Display also can be
connected to the SA Bus port (but only on FEC
models without integral display and push buttons).

The Sensor port is connected internally to the SA
bus terminal block. For more information about the

Supply power terminal block

The 24 VAC supply power terminal block is a gray,
removable, 3-terminal plug that fits into a board­mounted jack on the top right of the controller.

Wire the 24 VAC supply power wires from the
transformer to the HOT and COM terminals on the
terminal plug as shown in Figure 7. Do not use the
middle terminal on the supply power terminal block.
See for more information about the Supply Power
Terminal Block.

Note: The supply power wire colors may
be different on transformers from other
manufacturers. Refer to the transformer
manufacturer’s instructions and the project
installation drawings for wiring details.

Important: Connect 24 VAC supply power
to the field controller and all other network
devices so that transformer phasing is uniform
across the network devices. Powering network
devices with uniform 24 VAC supply power
phasing reduces noise, interference, and
ground loop problems. The field controller
does not require an earth ground connection.
