Application
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 capable of switching between MS / TP and N2 communication protocols. With a digital pressure sensor and a damper actuator, our VMA16 controllers are available in a small package that enables fast field installation and efficient space utilization. Our VMAs offer a wide variety of network sensor options for measuring zone temperature, duct temperature, zone content, carbon dioxide content and more.
