• Normally use the default values for these parameters.
• The AT Calculated Gain parameter sets the gain for when PID values are calculated using
AT. When emphasizing response, decrease the set value. When emphasizing stability,

increase the set value.
• The AT Hysteresis parameter sets the hysteresis for limit cycle operation during
autotuning when switching ON and OFF.
• The Limit Cycle MV Amplitude parameter sets the MV amplitude for limit cycle operation
during autotuning.
