1. Usage and performance characteristics
temperature detection: can detect water temperature and display;
Filter management: can be used for up to 4 groups of filter management and display (If customer needs, you can add more groups of filter display)
Through the high and low voltage switch can also detect water full,then stop; water less,then add water,and other functions.
Water quality detection: with water quality testing function can be detected RO filter,after water filtration if it meets the requirements.
