Scheme introduction：
This product solution overcomes the maintenance problem that the wireless room temperature collector needs to retrieve the charge and replace the dry battery every year. It is a standard 86 box installation mode, which uses AC220V single live wire power supply (built-in XD303 series high-performance single fire switch module, which stably realizes single fire power supply and intelligent charging functions, without flashing or burning the light). It can directly replace the old switch in the home (traditional mechanical wall switch), and supports single and dual control. Its installation position is fixed, it is not easy to move at will, the installation height is reasonable, and the collection temperature is accurate. It has become the best choice among all kinds of room temperature collection equipment. It is mainly used in the northern heating room, so that users, heating companies and management departments can understand the heating situation and effectively avoid heating disputes.
