Set point limitter

Parameters
The setting range of the set point is limited by the set point limitter. The set
point limitter is used to prevent the control target from reaching abnormal tem-
peratures. The upper- and lower-limit values of this set point limitter are set by
the "set point upper limit" and "set point lower limit" parameters in the "initial
setting level", respectively. However, note that when the set point limitter is
reset, the set point is forcibly changed to the upper- or lower-limit value of the
set point limitter if the set point is out of the limitter range. Also, when the input
type and temperature unit are changed, the set point limitter is forcibly reset to
the sensor setting range.
