Product Overview
Introduction
The BACnet VAV Actuator is the Siemens Building Technologies, Inc. FLN controller
used in pressure independent Variable Air Volume applications (Figure 1). It provides
Direct Digital Control (DDC) for eight applications, and can operate independently as
a stand-alone DDC room controller or networked with a field panel. The controller
provides all input/output, system, and local communication connections. Hardware
consists of the controller and the mounting bracket.
