The Selmo system consists of two complementary layers:
The switching mechanism – it is the logical layer that controls the process.
You can think of it as the brain of the machine.
This is where it is decided which state is active and when the next one follows.
The system layer (zone level) – it is the interface to reality.
Here the model communicates with the physical world – with buttons, sensors, valves, actuators or software functions.
Both layers together form a self-contained unit:
The switching mechanism provides the state information that the zones respond to with the appropriate actions and feedback.
