[0005] As a preference, the antenna interface II is an external antenna interface and / or a built-in antenna interface.

[0006] As a preference, the function setting key also includes a reset key.

[0007] As a further improvement, the WiFi module is connected and communicated with the mobile terminal APP.

[0008] The utility model installs the main controller on the bracket at the bottom of the solar water bucket, and then the sensor, solenoid valve, and electric heating leads installed on the solar water bucket can be directly connected to the main controller, eliminating the trouble of wiring indoors. A wireless display is added, and the main controller and the display use a 433MHz two-way communication module to achieve wireless communication. It is only necessary to provide power to the display, so that the solar water heater can be controlled through wireless communication, which is not limited by the installation site and is easy to operate.

[0009] The utility model wireless solar water heater controller realizes the connection with the wireless module through the technology development of the dedicated single chip microcomputer, and effectively increases the anti-interference ability and the rapidity and stability of the connection through the circuit board technology design. The antenna can be external or internal, and the layout of the internal antenna wiring is isolated from the power line.

[0010] The beneficial effects of the utility model are: the main controller is installed on the solar water heater, an independent display is added, which is not limited by the installation site, and the trouble of wiring indoors is avoided. The installation, operation and use are very convenient. The hot water status at home can also be conveniently observed and controlled through the mobile phone, providing convenience for family water use. BRIEF DESCRIPTION OF THE DRAWINGS
