Condition: The "additional temperature input display" parameter must be
set to ON and the "input type" parameter must be set to a non-contact
temperature sensor.
These parameters allow the input range to be shifted both at the upper and
lower limits (2-point shift) (as opposed to the "temperature input shift" parame-
ter, where the entire input range is shifted by a fixed rate (1-point shift)). A 2-
point shift enables more accurate offset of the input range compared with a 1-
point shift when the input shift values at the upper and lower limits differ.
This parameter sets input shift values for each of the upper and lower limits
(2-point shift) of the input range.

Condition: The control must be 2-PID control.
These parameters set the PID constants for control. The PID can be automat-
ically set by executing autotuning.
Proportional action:P refers to control in which the MV is proportional to the
deviation.
Integral action: I gives a control action that is proportional to the time inte-
gral of the control error. With proportional control, there is
normally an offset (control error). So, proportional action
is used in combination with integral action. As time
passes, this control error disappears, and the set point
comes to agree with the control temperature (process
value).
Derivative action: D gives a control action that is proportional to the time
derivative of the control error. As proportional control and
integral control correct for errors in the control result, the
control system will be late in responding to sudden
changes in temperature. Derivative action enables control
