Installation Notes：
Window Operation
The water meter is usually in a low-power off-screen state, and it can be woken up when the magnet is placed in the lower left corner of the screen (where the CPA logo is located). The magnet moves across the lower left corner of the screen to realize switching and cycling of the display window.
Window Display
Display order：Cumulative flow > Instantaneous flow > Time Meter Number > All screens on > all screens off
