I9-TTSBC: Triple Tank Sump and Bore Pump Controller

This model is specially designed to control Three water tanks and Two water pumps to supply water to the overhead tank from both Sump water and Bore water, one pump will be operated for an instance. Whenever water in any one of the overhead tanks or both overhead tanks becomes minimum water level, Initially sump water pump is operated to supply water to the overhead tank. If the water in the sump goes below the foot valve level, the sump motor switches OFF and activates the bore motor supplying water to the overhead tank. This unique mechanism ensures a sufficient water level in the overhead tank. This gives priority to the sump water even if the bore water pump is running. If the sump water level reaches 50%, the bore water pump switches OFF and activates the sump motor to pump water to the overhead tank.
