split range control is which the output of a controller is
split to two or more control valves. For eg,
For 0% controller output,valve A fully open & B fully
closed.
For 25%, Valve A 75% open,B 25% open
For 50%, Valve A& B- 50% open,
For 75%, Valve A 25%open, B-75%open..
For 100%, Valve A fully closed & valve B Fully Open..

Like this, d controller output action can be set depending
upon the application...
