Intelligent Control for Dual-Boiler System with Digital Communication for Smart Buildings

Smart buildings have nowadays many integrated systems, like HVAC (Heating, Ventilation and Air Conditioning). In general, every component has its own control system, and these can be independent on each other or can collaborate for more complex control law. In this paper, an intelligent dual-boiler monitoring and control system (DBMCS) through digital communication using OpenTherm protocol is proposed. It is capable of controlling two independent boilers or implementing an optimal control of the dual-boiler system. DBMCS has a graphical user interface and it contains an interconnection device based on microcontroller with double function, gateway and switching device between boilers and coordinating system.
