7-5-6 Heating Control Period (cp)
Cooling Control Period (c-cp)
Condition: The control must be set to 2-PID control when the cooling side
control period is cooling/heating control.
Function • These parameters set the control periods. Set the control periods taking
the control characteristics and the electrical life expectancy of the relay
into consideration.
• In a standard control system, use the “heating control period” parameter.
• In a heating and cooling control system, the control period can be set
independently for heating and cooling.

reverse operation increases the manipulated variable when the PV
decreases.
