The FW-VAV is a network VAV (variable air volume) input/output controller with Ethernet and Wi-Fi connectivity, as well as a 560 MHz GHz processor, 128 MB RAM, 32 MB flash memory, HTML5 graphics, a suite of applications and kits, and multifunctional adapter widgets.
The controller features five standard applications that you can download and commission with a web browser.
Important: Only use the controller as
an operating control. Design additional precautions into the control system where
failure or malfunction of the controller could lead to personal injury or damage to
the controlled equipment or other property. Incorporate and maintain other devices
that warn of or protect against controller failure or malfunction, such as
supervisory, alarm systems, safety, or limit controls.
