WRM30+ is equipped with a display and two buttons for the user interface. It is organized in two environments: one for
displaying and one to configure. In the first one there is a main screen which summarizes the most important information
of the system; then other main screens show in detail other values. The other environment concerns the configuration
where the operating parameters of the system are set. The various sequences are detailed in the following tables.
