(c) When CH Auto tuning instruction (Yn4 to Yn7) is turned off and on in the setting
mode and the module is shifted to the operation mode
After the module is shifted to the operation mode (Setting/operation mode instruction (Yn1) is turned off and
on), the simultaneous temperature rise parameter and PID constants are changed with auto tuning.
