Leonardo, the advanced plant management control unit.
What Leonardo is
Leonardo is the only unit of its kind that allows the integrated management of Lucas technologies (Bernoulli, Bernoulli Hybrid, Bernoulli Booster and Heron): a slim and compact controller that offers a high degree of communication and excellent performance.
Leonardo is ideal in all those plants where supervision and management is required, in order to create energy efficiency. It is also used to manage “multi energy” in our systems, for example in plants where multiple Lucas technologies coexist, therefore in complex systems where efficient management of multiple energy sources is required (Bernoulli, Heron, photovoltaic, solar thermal, back-up generators, etc.).

Leonardo: fields of application
Leonardo is integrated in some Lucas technologies: Bernoulli Hybrid and Heron.
It is precisely in Heron HE003M that Leonardo proves to be essential, becoming the conductor of the boiler room: thanks to the control of the plant temperatures, the external temperatures, the climatic curves, the mixed zones, the production of DHW and much more, Leonardo allows Heron to manage user requests in the most efficient way. All this is completed by the remote monitoring and control service, alarm remote management and maintenance remote management.
