■When 'CH1 Auto tuning command' (Y4) is turned from OFF to ON in the setting mode and the
mode is shifted to the operation mode
After the mode is shifted to the operation mode ('Setting/operation mode command' (Y1) is turned from OFF to ON), the
simultaneous temperature rise parameter and PID constants are changed by the auto tuning.
