VMA1615 and VMA1630 Variable Air Volume Controllers
Installation Instructions
MS-VMA1615-0U, MS-VMA1615-1U, MS-VMA1630-0U,
MS-VMA1630-1U
Applications
The VMA1615/1630 programmable digital controllers are
designed for VAV applications that communicate through
the MSTP or N2 protocol. These 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 wired network sensors
for zone and discharge air temperature sensing.
Important: The MS-VMA1615-xU and
MS-VMA1630-xU models are used in
Metasys Release 8.1 smoke control
applications and are UL 864 UUKL/UUKLC
10th Edition Smoke Control Listed. You
must refer to the Metasys® System UL 864
10th Edition UUKL/ORD-C100-13 UUKLC
Smoke Control System Technical Bulletin
(LIT-12012487) for detailed requirements
and procedures for installing,
commissioning, and operating UL 864
UUKL/UUKLC Listed Metasys system
devices. The UL 864 UUKL/UUKLC listing
for Smoke Control Equipment is voided if
(1) you do not use the required software
tools at the required versions; or (2) you do
not meet the requirements or do not follow
the procedures as documented in the
Metasys® System UL 864 10th Edition
UUKL/ORD-C100-13 UUKLC Smoke
Control System Technical Bulletin
(LIT-12012487).
Switchable Communications
Protocols
By default, the Metasys® system FEC Family Controllers
and network sensors communicate using either the
standard BACnet protocol, based on the ANSI/ASHRAE
135-2004, or the BACnet/IP protocol. The BACnet
protocol is a standard for ANSI, ASHRAE, and the
International Standards Organization (ISO) for building
controls.

Part No. 24-10143-01604, Rev. —
Refer to the
QuickLIT website
FEC, VMA, and most IOM field controllers are BTL-listed
as BACnet Application Specific Controllers (B-ASCs).
FAC field controllers and the VMA1930 Field Controller
are BTL-listed as BACnet Advanced Application
Controllers (B-AACs).
Release 10.3 with Release Module (RM) 10.2 of the
Controller Configuration Tool (CCT) can be used to switch
the Field Bus communications protocol in supported FEC,
FAC and VMA controllers to be either the standard
BACnet MSTP or the N2 protocol. All new controllers use
BACnet MSTP as the default communications protocol.
Switchable communications protocols in the MSTP
models provide a cost-effective upgrade and
modernization path for customers with existing N2
controllers.
The N2-capable FEC Family Controllers can be used as
functional replacements for legacy N2 controllers. The
N2-capable FEC Family Controllers:
•
have the input and output (I/O) quantities and
characteristics of the FEC 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
•
are available in Buy American versions (most models)
•
are listed for UL864 UUKL/UUKLC (some models).
N2 is supported as part of the Metasys® 10th Edition
listing for Smoke Control System Equipment.
The N2-capable FEC family controllers:
•
do not support Zone Bus (for example, TMZ sensors
and M100 actuators) or XT-Bus (System 91) devices
(for example, XT, XTM, and XP modules)
•
do not support a wireless connection to the N2 bus
•
do not support NxE passthrough
