When the level is lower than b, D6 outputs low level, D5 outputs high level. D1-D4 output low level. VL is red. K is connected. KM is connected. M begins to feed water. When the level reaches c, D6,D1-D4 output high level. K and KM are released. M stops working. When the level is lower, D6 outputs high level, M doesn't work. When the level is lower than b, M begins to work. The circuit works in such a way to keep the level moving between b and c.
