This technical report outlines the integrated sequence of operation for coordinating multiple AIRSYS lead/lag HVAC controllers to achieve an effective control scheme. It discusses the benefits of using multiple controllers, including improved system efficiency and reduced maintenance costs through balanced wear and tear. The report details the control logic, which includes methods for cooling such as Free Cooling (FC) and Direct Expansion (DX), and emphasizes the importance of optimizing control setpoints and sensor placement. Three case studies are presented, each illustrating different control objectives and solutions for managing HVAC systems in various configurations. The case studies highlight the need for careful planning in controller setup to ensure effective temperature management and runtime distribution among units. The document concludes by suggesting that adapting the solutions from the case studies can address specific site requirements, encouraging further inquiries for tailored control recommendations.
