1. A circuit for bi-state control of the operation of a deep well pump engine, containing a value setting device, signals transducers and a controller with output connected with the pump unit engine, characterized in that it has a tubular capacitive sensor (1) submerged in the deep well (2), connected via a transducer (3) with the adder input (4), and to the second input, to which a water level setting device (5) is connected, and the output of the adder (4) is connected via a controlled gain amplifier (6) with the input of a set of comparators (8), with the output connected to the controller input (9).<IMAGE>
