controller, which can be integrated to any supervisory
controller capable of managing N2 Open networks and Figure 1: VMA1832 Controller
devices, such as the Network Communication Module
(NCM) and Network Automation Engine (NAE).
The VMA1832 controller features an advanced design
that provides optimum performance and easy access to
power, network, and field terminations. These controllers
come with 32-bit microprocessors that meet and exceed
ever demanding industry standards.
Note: A software download that allows VMA1832
controllers to communicate as
BACnet® Multidrop Serial Bus/Token Passing
(MS/TP) devices will be available at a future date.
This functionality provides a differentiated and
cost-effective platform upgrade path for existing
customers who are looking for a gradual upgrade
strategy and should be considered during
installation of the controller.
Features and Benefits
Features Benefits
N2 Open Communications Protocol Can be integrated into existing N2 networks, which extends the life of the existing
Metasys system installations.
Standard Software Platform Uses a common software design to support use of a single tool for control
applications, commissioning, and troubleshooting to minimize technical training.
Auto Tuned Control Loops Reduce commissioning time, eliminate change-of-season re-commissioning,
and reduce wear and tear on mechanical devices.
Universal Inputs and Binary and Allow multiple signal options to provide input/output flexibility.
Configurable Outputs
Optional Local Controller Display/Keypad Allows convenient monitoring and adjusting capabilities at the local device.

Controller Configuration Tool
The Controller Configuration Tool (CCT) is used to
configure, simulate, and commission the VMA1832
controllers on an N2/FC bus.
The Configuration mode allows you to select a number
of mechanical and control logic options through System
Selection Trees for typical air handling, terminal unit, VAV
box, and central plant mechanical systems (Figure 2).
When required, you can customize the standard logic
provided by the system selection process to meet your
specialized control logic requirements. Configuration
mode also allows you to customize certain display options
available to controllers that use a local controller display.
Figure 2: Mechanical Selection in CCT
For VAV applications, CCT features an optional box flow
test to automatically exercise the VAV box to ensure
correct mechanical installation and proper configuration
of the key flow setup parameters. Additionally, the
Metasys system provides multiple configurations of room
network sensors and a handheld VAV balancing tool that
can be used to perform VAV balancing tasks.
In addition, the Commissioning wizard has a Balancer
tab for VAV applications to easily auto calibrate VAV
boxes and set flow constants in one location.
A Commissioning mode only version of the CCT software
is available to the Johnson Controls® branch offices for
jobs or individuals having only commissioning tasks (for
example, balancing contractors). The Configuration and
Simulation modes are disabled in the CCT
Commissioning software.

monitor room temperature. Options are available to also
monitor zone humidity, carbon dioxide (CO2), local
temperature setpoint adjustments, occupancy, and other
variables. This data is transmitted to a field controller on
the SA Bus.
The VMA1832 controller is able to reuse existing TE-6xxx
Series Sensors from existing VMA14xx installations using
an adapter included with the VMA1832 controller.
TMZ-1600 applications require use of a new sensor when
installing a VMA1832. The VMA1832 controller can be
used with a WRZ Series Wireless Sensor and a
WRZ-7860 Series One-to-One Receiver. The VMA1832
can also reuse existing TE-700 Series Sensors from
existing VMA14xx installations. The VMA1832 also
supports the TE-730 Series Sensor.
Figure 4: NS Series Network Zone Sensors Applications
The VMA1832 controllers can be configured for both
single-duct and dual-duct VAV box applications. The
VMA1832 controllers require an additional damper
actuator and Differential Pressure Transducer (DPT)
sensor for dual-duct or supply/exhaust applications.
Note: Connecting an Input/Output Module (IOM) to the
VMA1832 via the SA Bus connection is not
supported.
Hardware
The VMA1832 controllers are enclosed in a plastic
housing with an attached metal shield. The controller,
transducer, and actuator are all integrated into a single
enclosure.
The VMA1832 controllers’ housing may eliminate the
need for a separate enclosure for the VMA. Check code
requirements for appropriate applications.
