5-13 Using PID Sets
One set of all the parameters that are related to 2-PID control are called a PID set.
• You can register up to eight PID sets.
• There are the following two ways that you can specify PID sets.
• Setting a Fixed PID Set
• Using Automatic Selection of PID Sets by Zone
• You can specify the PID set selection method for each program in the PID Set No. parameter in the
Program Setting Level.
• The same PID sets are used for all programs.
