Chapter 1 – Product Overview

The BACnet Actuating Terminal Equipment Controller (ATEC) is the Siemens Industry
FLN controller used in pressure independent Variable Air Volume applications (See the
following figure.). 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.
