SP Lower Limit
• 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.
• For a temperature input, the decimal point position depends on the currently selected
sensor, and for an analog input it depends on the Decimal Point parameter setting.
