Before you write the program, configure these inputs, outputs, and variables<br />
in your <strong>Tracer</strong> MP580/581 controller.<br />
Also, because you are programming a constant-volume air-handling unit,<br />
set the controller to use the SCC profile. For more information about configuring<br />
the controller, including setting it to use the SCC profile, see the<br />
<strong>Tracer</strong> MP580/581 Programmable Controller <strong>Programming</strong> guide<br />
