Variable Air Volume Modular Assemblies (VMAs)

At Johnson Controls, our VMAs are designed to provide the best control for Variable Air Volume (VAV) boxes. With 32-bit processors, our VMA16s and VMA1832s are programmable controllers that can switch between MS/TP and N2 Communications protocols. Featuring a digital pressure sensor and a damper actuator, our VMA16 controllers come in a small package that facilitates quick field installation and efficient use of space. Our VMAs feature a wide variety of network sensor options for measuring zone temperature, duct temperature, zone humidity, carbon dioxide levels and more.
