The controller 24 can be electrically connected to various components such as the water temperature sensor 8, radar level sensor 9, inlet valve 7, heater 3, solenoid valve 16, and booster pump 17. By receiving data from the water temperature sensor 8 and radar level sensor 9, it displays the water temperature and level information in the hot water tank 2 in real time on the display screen, allowing users to intuitively understand the working status of the water heater. Users can also preset parameters such as heating temperature and descaling time through the controller 24. The controller 24 automatically controls the opening and closing of the inlet valve 7, the start and stop of the heater 3, and the operation of the solenoid valve 16 and booster pump 17 in the descaling mechanism according to the preset parameters, realizing the automated operation of the water heater without the need for frequent manual operation by the user, greatly improving the convenience and comfort of use. All components of the entire water heater work together in a coordinated manner, with complete functions and a scientific and reasonable design, providing users with a safe, efficient, and convenient hot water experience.
