ABSTRACT:
A method for controlling a digital shower system includes the steps of: actuating the digital shower system for operation; detecting whether the system is in order or not, and if not, generating an error message; otherwise, performing the next step; entering a ready mode, for discharging in advance a water flow in an outlet pipe that does not reach a preset outlet water temperature; entering a shower mode, in which a desired message is input through a digital user interface, a water outlet is controlled by a control unit to continuously output water maintained at the same temperature as the preset outlet water temperature; and providing several preset power-off conditions for automatically turning off the digital shower system. The method may not only achieve the function of discharging water in advance, but also automatically shut off the water output in a certain time period, so as to save water.
