Executing Heating/Cooling Control Section 4-4
Automatic Cooling
Coefficient Adjustment
By executing AT during heating/cooling control, the cooling coefficient can be
automatically calculated along with the PID parameters.
Note If there is strong non-linear gain for the cooling characteristics, such as when
cooling water boils for cooling control, it may not be possible to obtain the opti-
mum cooling coefficient at the Controller, and control may take the form of
oscillating waves. If that occurs, increase the proportional band or the cooling
coefficient to improve control.

To set heating/cooling control, set the Standard or Heating/Cooling, Dead
Band, and Cooling Coefficient parameters.
