The self adjusting technology will automatically adjust the water pressure and energy output after reading the incoming water temperature by itself. It brings two benefit in using, to keep water temperature and flow steady and to ensure only small amount of energy is used all the time. Stiebel, Takagi and some of Noritz tankless water heaters adopt the skills.
