Used to select a group of PID parameters according to a deviation from
the given target setpoint. The controller uses the PID parameters of the
number selected in PID group number (GRP) if the PV input falls outside
the given deviation range.
The following example shows a case when only the reference deviation
is set without setting any reference point. The selected set of PID
parameters is as follows.
Since region 1 is within the deviation range, the controller uses the 1st
group of PID parameters.
Since region 2 is outside the deviation range, the controller uses the
PID parameters of the number selected in PID group number (GRP).
