Default unit setpoints
Many of the control parameters are automatically configured by pressing this button
after the Sales Order screen is entered. Failure to press this button can result in
unstable control. Note that some versions of software also have a Default Setpoints
button on the Capacity Control screen. That button does not need to be pressed
because the Default Unit Setpoints button on the Diagnostic screen will set all of the
parameters.
