This paper presents a solution for managing an air handling unit (AHU) through a Building Management System (BMS), with a special focus on component selection and interconnection, control logic, and safety functions. Key elements of the AHU such as fans, heaters, heat recovery units, coolers, humidifiers, and relevant sensors are analyzed in detail. The operating principles and wiring of components are described through electrical schematics, including the use of EC motors. The integration with the BMS system using Schneider Electric equipment is elaborated. Safety operation criteria are addressed, along with logic sequences implemented via relay technology that govern both normal and alarm operating modes of the AHU.
