technical field

The utility model relates to a solar water heater controller.

Background technique

Solar energy is more and more popular because of its environmental protection, pollution-free, cheap and other characteristics. Many families and public places are using solar water heaters. However, solar energy is greatly affected by the weather. When there is insufficient sunlight at night or on cloudy days, the water in the water tank may not reach the set temperature. At this time, it is necessary to use auxiliary heating to heat the water in the water tank to a sufficient temperature. Meet the requirements of users for all-weather use.

At present, solar water heaters are developing rapidly, and many manufacturers have met the basic needs of customers. For example, electric heating is used as the auxiliary heating method. The controller has time display, water level display and temperature display. electricity and meet the requirements of different users' usage habits. In addition, it also has functions such as short circuit protection, leakage protection, anti-dry heating, power failure protection, fault alarm and manual control.

So many control functions need to be realized by selecting the buttons on the solar water heater, which is cumbersome, and solar water heaters are used in places with high humidity, and it is easy to cause danger due to electric leakage when pressing the buttons.
