EV5 automatic water pumping/draining/feeding controller is a multi-purpose controller with more powerful functions than EV3 and can be widely used in a variety of applications with excellent durability and flexibility.
1. With duplex intelligent control of upper water tank and lower water well, the controller is able to carry out unattended automatic water pumping and refilling operations, that is, automatically pumping water from the water well into the upper water thank for water refill when the upper water thank is short of water, or automatically pumping water into the upper water tank for storage when the lower well or pool is full.
2. The product can be widely used in various applications requiring single water draining/pumping control.
3. With water refilling control of single water tank and tower, the controller is able to automatically start water refilling when the water level is below the lower limit, and automatically stop water refilling at the full water level.
4. The controller, equipped with a manual water feeding button, allows users to manually control the water refilling operation temporarily in order to facilitate commissioning and adjustment during the initial installation.
5. With the important water shortage protection function, the controller can prevent the pump from damages caused by dry running in case of no water.

答：可以的，EV5可以只用A,C两根线控制满水位，满水停止输出，低于满水开始输出，不过满水时会延时约30秒后才停止输出。注意接线时必须将C,D,E短路。
答：这个是因为PVC管上有水膜导致的，而且低水位的传感器和公共极比较近，最容易发生此类问题。简单解决方法就是将公共极离远补水探极或则干脆不要绑在PVC管子上；建议如果要安装在PVC管上探极一定不能挨着PVC管。
答：液位传感器线最远可以拉100米的距离，延长的导线也没有特殊要求，用普通的网线即可，但是不能和强电在一个管子里走线。
答：控制器内部是一个6A的继电器，考虑应用余量，如果接水泵，100W以下可以直接接，超过100W的需要用中间继电器（或交流接触器）扩容转接，如果是接电磁阀，因为电磁阀的功率通常都比较小，可以直接控制。
