  • Page 11: Product Overview

    Product Overview Introduction The Unit Vent Controller—0 to 10V Output is the Siemens Building Technologies, Inc. Terminal Equipment Controller (TEC) used in unit ventilator applications. See Figure 1. It provides Direct Digital Control (DDC) for five applications. The controller can operate as an independent, stand-alone, DDC room controller or be networked with an APOGEE field panel.
