5-38 Parameter Functions & Definitions
Manual Reset Value
Conditions of Use: The control mode must be standard control with the
2-PID control method configured. In addition, the Integral Time parameter
must be set to 0.
Function: This parameter allows you to configure the manipulated variable to
remove offset during stabilization of P or PD control.
Related Parameters
• PID ON/OFF (Initial Setting function group, page 5-55)
• Integral Time (Adjustment function group, page 5-35)
Hysteresis (Heating)
Hysteresis (Cooling)
Conditions of Use: The control method must be ON/OFF control. For
Hysteresis Cooling the control mode must be heating and cooling.
Function: This parameter allows you to configure the hysteresis function to
help ensure stable operation during ON/OFF control. For more details, refer
to page 3-26,
Hysteresis.
• In the standard control mode, use the Hysteresis Heating parameter.
The Hysteresis Cooling parameter cannot be used in standard control
(refer to Figure 3.24).
• In the heating and cooling control mode, the Hysteresis parameter can
be set independently for heating and cooling. Use the Hysteresis
Heating parameter to configure the heating Control Output, and use the
Hysteresis Cooling parameter to configure the cooling Control Output
side hysteresis (refer to Figure 3.25).
