光电复合热水取暖控制器的研制

开发设计了一种利用太阳能热并能用电补充加热的光电复合热水取暖控制器，该控制器具有水箱水位、水温的显示和检测功能，并可根据需要随意设定水位、水温、最关键的是其具有漏电检测保护功能，本文阐述了控制器的工作原理及特点，介绍了它的硬件实现和软件设计。该装置试运行已经取得了成功。

Design to a controller for heating system of solar and eletrical energy

A device has been developed which controls a water heating system. The water is heated not only by solar energy but also by electricity for the complement.It can check,indicate the water level and the temperture of the tank.A key function is the automatic protection system for electricity leakage.The working principle,characteristics,hardware structme and the software design are introduced in this paper.
