Heat or Cool Linearity
Select an output curve. For a nonlinear process, select
CURVE 1 or CURVE 2.
Selectable values: CURVE 1, CURVE 2, or LINEAR. Refer
to Figure 4.4.
Figure 4.4 Linear and Nonlinear Outputs
If curve 1 or 2 is selected, a PID calculation results in a low-
er actual output level than the linear output requires. One
of the nonlinear curves may be used when the response of
the system to the output device is nonlinear.
