D : 带wifi功能机型时间自动校正; 定时开关可以在手机APP里设定。
D : Automatic time correction for models with wifi function; The timer switch can be set in the mobile app.

原机组有高低压水流保护口天的请对四链接控制掠，原勍系统没有保护口天可用导结链捡高压低压水流保抑口天；或者在工厂设置里取消保抑円天。
The original unit has high and low pressure water flow protection, please control the four links, the original system does not have protection, and the high-pressure and low-pressure water flow can be picked up by the guide chain to protect the mouth day; Or cancel the protection in the factory settings.
