• These parameters set the upper and lower limits for the SP setting. The
SP can be set within the range defined by the upper and lower limit set
values in the "set point upper limit" and "set point lower limit" parameters.
If existing SP settings are out of the range, they will be changed to either
the upper or lower limit values (which-ever is closest).
• When the temperature input type and temperature unit are changed, the
set point upper limit and set point lower limit will be changed to the upper
and lower limits of the sensor.
• During temperature input, the decimal point position is dependent on the
currently selected sensor. During analog input, it is dependent on the
"decimal point" parameter setting.

• This parameter selects 2-PID control or ON/OFF control as the control
system.
• The AT tuning function can be used in 2-PID control.
