A wide rage auto turn OFF timer covering 1 minute to 20 hours in three ranges with S1. As soon as power is applied to the circuit the IC1  starts to oscillate happily and feeds clock pulses to the IC2 . The IC2  and IC3  give a combined count rate of 81920 before the output of the IC3  goes high and turns Q1 on. With pot RV1 adjust the Time.
