Variable Air Volume Modular Assembly (VMA)
1400 Series
The Variable Air Volume Modular Assembly (VMA)
Series is a family of configurable digital controllers.
Each model in the VMA1400 Series combines a
controller, pressure sensor, and/or actuator housed in
one preassembled unit.
Unique features that reduce installation and
commissioning time while enhancing Variable Air
Volume (VAV) system operation make the VMA the
product of choice for VAV systems.
The VMA1400 Series is available in four models:
• Cooling Only (VMA1410)
• Cooling with Reheat and/or Fan (VMA1420)
• External Actuator (VMA1430)
• Metasys® Zoning Package (VMA1440)
Note: The VMA1440 is used exclusively as part of Figure 1: VMA1430 and VMA1410/1420
the Metasys Zoning Package. See the Metasys Zoning (1440 Not Shown)
Package Product Bulletin (LIT-639050) for details.
Features and Benefits
Integrated Module Includes controller, pressure sensor, and/or
actuator, preassembled to reduce installation
time
Enhanced Actuator Provides a fast response stepper motor that
(All Models but 1430) drives the damper from full open to close in
30 seconds
Automated Commissioning Uses Proportional Adaptive (P-Adaptive) and
(All Models but 1440) Pattern Recognition Adaptive Control (PRAC)
for continuous loop tuning
Advanced Diagnostics Offers damper stall detection, starved box
detection, actuator motor duty cycle, VAV box
flow test, and other diagnostics on most models
Network Communications Enables integration into a Building Automation
System (BAS)
Easy Configuration Provides simple question/answer software format
for quick selection of project-specific applications
Software Addressing Allows remote addressing and identification
from a configuration tool
