Abstract

Each desired value is recorded and stored in memory as a steamer operates for the first time when it is brand-new and filled with fresh water for the first time. The time gap between two consecutive fresh water refills at boiling temperature for the water in the steamer sets important operating parameters, which are the steamer's water boiling temperature according to geographical height, the filling time between low and high water levels fixed by devices monitoring water levels, the filling time up to the highest level after complete emptying and the speed at which the temperature of the water in the steamer changes.
