Applications
The VMA1615/1626/1628/1630 programmable digital
controllers are designed for VAV applications that
communicate through the BACnet® MS/TP or N2
protocol. These VMA controllers feature combinations of
an integral digital pressure sensor (DPT), a damper
actuator, and a 32-bit microprocessor. The VMA1626 has
an actuator but does not contain a DPT. The VMA1628
model has a DPT but does not contain an actuator. 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 and wireless
network sensors for zone and discharge air temperature
sensing.
Switchable Communications
Protocols
The Metasys® system FEC Family Controllers and
network sensors communicate using either the standard
BACnet protocol, based on the ANSI/ASHRAE 135-2008,
or the BACnet/IP protocol. The BACnet protocol is a
standard for ANSI, ASHRAE, and the International
Standards Organization (ISO) for building controls.
FEC, VMA16, VMA18, 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 10.1 and later 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 MS/TP
or the N2 protocol. All new controllers use either BACnet
MS/TP as the default communications protocol, or
BACnet/IP. Switchable communications protocols in the
MS/TP 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
• support WRZ wireless sensors from the controller
using the WRZ-7860 receiver (most models)
• are available in Buy American versions (most models)
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
North American Emissions
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.
