A fully automated system for controlling water purification units based on distillation. Control parameters in the system include an overall power inpu t fuse (2) that protects against electrical shorts, a manual reset switch (3) that resets the whole system to an initial state, a thermal overload switch (1) that protects the boiler against running dry, a product level switch (4) that prevents the product tank against overflow, a boiler pressure switch (5 ) that maintains the proper level in the boiler, an inlet solenoid (6) that controls the flow of inlet water, a boiler drain solenoid (8) that controls the periodic draining of the boiler, a timer delay relay (9) that prevents water produced during transient conditions from entering the product container, a product output solenoid (10) that directs product water either to the product container - or a waste stream, and three indicator lights (11,12,13) that provide continuous operational status.
