When the level is lower than c, V1 V3 are disconnected and +12V voltage is put on V2, making V2 connected.K is connected and KM begins to work. M begins to feed water. When the level reaches C, V3 has a low level and is connected. Its integrated electrode becomes low level. VD4 is disconnected and K1 is connected. M keeps on working. When the level reaches b, V1 has a high level and is connected. Its integrated electrode becomes low level. V2 is disconnected and K is released. M stops working . When the level is lower than the lowest level, M begins to feed water again.
