General Description
Component Data
The MicroTech Unit Ventilator Controller (UVC) is a microproces-
sor-based controller designed to provide sophisticated control of
an economizer-equipped AAF-HermanNelson unit ventilator. In
addition to providing normal operating control, the MicroTech UVC
provides alarm monitoring and alarm-specific component
shutdown if critical system conditions occur.
Each UVC is factory wired and factory programmed for the spe-
cific unit ventilator model and configuration options ordered by
the customer. The UVC can be wired and programmed to oper-
ate as a stand-alone controller, as a master or slave
controller, or as a MicroTech network controller.
Communication ports allow networking capability and
access to any UVC from an IBM compatible personal computer
(PC) equipped with Monitor software.
The MicroTech Unit Ventilator Controller (UVC) is shown in
Figure 1.
