Heating/cooling control, Advanced PID control
If there is a large difference in the heating and cooling characteristics
of the object and satisfactory control is not possible using the same
PID constants, the heating P (proportional band) can be multiplied by a
coefficient for use in cooling control.
• The cooling P in heating/cooling control is obtained using the
following equation and the coefficient is set accordingly.
Cooling P = Cooling coefficient
Setting range
0.01 to 99.99

PID Proportional Band (PID Setting Level) (P. 8-40)
c-db
This parameter sets an output dead band for heating/cooling control. A
negative value can also be set to create an overlap band.
• Set an area centered on the SP where the control amount is 0
during heating/cooling control.
Setting range
