Adjustment Level Section 7-4
7-4-9 Cooling Coefficient (c-sc)
Condition: The control must be either heating and cooling control or 2-
PID control.
If the heating and cooling characteristics of the control target differ enough to
prevent satisfactory control characteristics from being obtained by the same
PID parameters, adjust the proportional band (P) on the cooling side by add-
ing the cooling coefficient to control cooling.
Function In heating and cooling control, cooling side P is calculated by the following for-
mula to set the cooling coefficient:
Cooling side P = Cooling coefficient
× P (proportional operation)
