Operation
In the example at left, the PID Set Automatic Selection Data parameter
is set to "PV."
When PV 200.0°C, PID Set 1 is used
When 200.0 < PV 400.0°C, PID Set 2 is used
The PID Automatic Selection Range Upper Limit parameters are set
so that the values increase as the PID set numbers increase.
The value for PID set 8 is internally fixed so that the Automatic
Selection Range Upper Limit parameter is set to 999.9% FS.
To prevent chattering when changing PID sets, hysteresis can be set
in the PID Set Automatic Selection Hysteresis parameter.
The PV, DV (deviation), or SP can be set for the PID Set Automatic
Selection Data parameter.

Hysteresis
Independent operation or coordinated operation can be used when 2-
channel standard control or 2-channel heating/cooling control is
selected.
Note: Multi-channel program operation is not possible if heating/
cooling control is selected for a model with two outputs.
The following table shows the number of programs if the Independent
Operation/Coordinated Operation parameter is set to "Independent
