Split Valve Configuration 
A common heat or cool type process requires two valves.  In this case the controller has only one output.  
The two motor positioners are calibrated differently, one responds to 4 to 12mA and the other responds 
to 12 to 20mA.  At 12mA, both valves are closed; one opening below 12mA and the other above 12mA.  
Refer to Figure 20 for an interconnection diagram for split valve operation using two actuators.
