Overview
Generic Controller I/O Layout. See
Wiring Diagram for application specific details.
Application 6689 is the slave mode application for the BACnet PTEC Unit Conditioner
Controller (550-433PA). Slave mode is the default application that comes up when
power is first applied to the controller. Slave mode provides no control. Instead, it
allows the operator to perform equipment checkout before a control application is put
into effect and to set some basic controller parameters (CTLR ADDRESS,
APPLICATION, and so on.).
