• These parameters set the upper and lower limits of the set points. A set
point can be set within the range defined by the upper and lower limit set
values in the SP Upper Limit and SP Lower Limit parameters. If these
parameters are reset, any set point that is outside of the new range will be
forcibly changed to either the upper limit or the lower limit.
• When the temperature input type and temperature unit have been
changed, the set point upper limit and set point lower limit are forcibly
changed to the upper and lower limits of the sensor.
• During temperature input, the decimal point position depends on the cur-
rently selected sensor, and during analog input it depends on the Decimal
Point parameter setting.
