be set by selecting a specific commodity. If
OPTI-SET is turned ON, a list of all available
commodities will appear. The commodity selected
will appear in the setpoint menu. If a change is
made to any of the below variables after selecting
a commodity, OPTI-SET will go from ON to
CUSTOM and the displayed commodity will go
away.
