Metasys, VAV Modular Assemblies

VMA16s (32-bit) are programmable digital controllers tailored for VAV
applications that communicate via the BACnet Master-Slave/Token-Passing (MS/TP) protocol. The VMA16
(32-bit) controllers feature an integral digital pressure sensor, an integral damper actuator, and a 32-bit
microprocessor. The controllers' small package size facilitates quick field installation and efficient use of
space, while not compromising high-tech control performance. The VMA16 (32-bit) controllers connect
easily to the NS Series Network Sensors for zone
and discharge air temperature sensing.

These features make the VMA16 (32-bit) the product of choice for VAV
systems. The wide variety of network sensor models provides options
for measuring and displaying zone temperature, occupancy detection,
duct temperature, zone humidity and dewpoint determination, carbon
dioxide (CO2) level, setpoint adjustments, VAV box fan speed control,
and discharge air temperatures.
