[Parameters]
• PID control: Normal setting
• PD control: Set a PB value slightly smaller than and a TD value slightly larger than the respective values for PID.
• Manual reset: Equal to MV value when the deviation equals ‘0.’
• Deviation and deadband set values: Set the above values first and choose appropriate deviation and deadband values so
to avoid integral (reset) windup while maintaining the shortest rise time.
