VMA1617 and VMA1632 VAV Controllers

Installation Guide

Applications

The VMA1617 and VMA1632 programmable digital

controllers are designed for Variable Air Volume

(VAV) applications that communicate through the

BACnet

®

 MS/TP or N2 protocol. These Variable

Air Volume Modular Assembly (VMA) controllers

feature combinations of an integral digital pressure

sensor (DPT), a damper actuator, and a 32-bit

microprocessor. The controllers' small package size

facilitates quick field installation and efficient use

of space without compromising high-tech control

performance. These VMA controllers connect easily

to the non-communicating sensor for zone air

temperature sensing.

Switchable communications
protocols

By default, 

 Metasys

®

 system 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.
VMA16 controllers are BTL-tested and listed as

BACnet Application Specific Controllers (B-ASCs).
Release 10.1 and higher of Controller Configuration

Tool (CCT) can be used to switch the Field Bus

communications protocol in this controllers

to be either the standard BACnet 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.
The N2-capable controllers can be used as functional

replacements for legacy N2 controllers. The N2-

capable controllers have the following features and

benefits:
• Have the I/O quantities and characteristics of

Metasys

 family controllers

• Must be programmed with CCT, which has similar,

but not identical programming capabilities as

HVACPro, GX9100, GPL, and other legacy tools

• Support SA Bus devices
• Support WRZ wireless sensors from the controller

using the WRZ-7860 receiver

• Are available in Buy American versions (most

models)

The N2-capable controllers 

do not

 support the

following features:
• Zone Bus (for example, TMZ sensors and M100

actuators) or XT-Bus (System 91) devices (for

example, XT, XTM, and XP modules)

• Wireless connection to the N2 bus
• NxE passthrough

compliance

United States

This equipment has been tested and found to

comply with the limits for a Class A digital device

pursuant to Part 15 of the FCC Rules. These limits

are designed to provide reasonable protection

against harmful interference when this equipment

is operated in a commercial environment. This

equipment generates, uses, and can radiate radio

frequency energy and, if not installed and used in

accordance with the instruction manual, may cause

harmful interference to radio communications.

Operation of this equipment in a residential area

may cause harmful interference, in which case the

users will be required to correct the interference at

their own expense.
