VMA1610 and VMA1620 Variable Air Volume Controllers
Installation Instructions
MS-VMA1610-xU, MS-VMA1620-xU
Applications
The VMA1610/1620 controllers are part of the Metasys®
family. VMA field controllers feature an integral 4 Nm
damper actuator and Differential Pressure Transducer.
VMA controllers run pre-engineered and
user-programmed applications required to monitor and
operate a wide variety of VAV boxes.
The VMA controllers operate on an RS-485 BACnet®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Application Specific Controllers (B-ASCs) and integrate
into the web-based Metasys system.
Note: Only -xU models of these controllers are available.
These models are for smoke control applications
only. If your application is not for a UL 864 UUKL
10th Edition smoke control application, please
review the product selection before installation.
Important: In Metasys® system smoke control
applications, use only the VMA1610 and
VMA1620 models that are UL 864
UUKL/UUKLC 10th Edition Smoke Control
Listed. For Metasys system smoke control
applications, you must refer to the Metasys
System UL 864 UUKL Tenth Edition 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 UUKL Tenth
Edition Smoke Control System Technical
Bulletin (LIT-12012487).

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.
Canada
This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de la Classe (A) respecte toutes
les exigences du Règlement sur le matériel brouilleur
du Canada.
Installation
Observe these guidelines when installing a VMA16
controller:
•
Transport the controller in the original container to
minimize vibration and shock damage to the VMA
controller.
•
Do not drop the controller or subject it to physical
shock.
Parts Included
•
one VMA16 controller with removable bus and power
terminal blocks
•
one installation instructions sheet
