EL6 CPU
The CPU represents the mind of the entire system and it's programmable without the use of any programming language. Wash programs are composed by cycles, which in turn are composed by steps. The scope of this programming pyramid (programs > cycles > steps) is to allow to plan an infinite number of integrated functions: this way, the CPU has perfect control of the washing machine in which it is installed and it can predefine the right reactions to any incoming event.
