They are integrated mechanical and control systems designed to maintain thermal comfort, indoor air quality, pressurization, humidity, safety, and energy efficiency within buildings and industrial facilities. Behind every air handler, chiller, boiler, fan, pump, and control valve lies a carefully coordinated sequence of operation that determines how the system starts, responds to load changes, protects itself, and shuts down safely.\u003c\/p\u003e\u003cp\u003eThe sequence of operation is the \"logic\" of the HVAC system. It defines how equipment communicates, how sensors and controllers interact, and how decisions are made automatically by the Building Management System (BMS) or standalone controllers. A well-designed sequence ensures that systems operate reliably, efficiently, and safely under all operating conditions, from normal occupancy to emergency events such as fire alarms, power failures, or freeze conditions.\u003c\/p\u003e\u003cp\u003eIn practice, HVAC systems operate through layers of control: \u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSafety interlocks protect equipment and occupants.\u003c\/li\u003e\n\u003cli\u003eStart-up logic establishes stable operating conditions.\u003c\/li\u003e\n\u003cli\u003eModulating control loops maintain temperatures, pressures, and airflow.\u003c\/li\u003e\n\u003cli\u003eEquipment staging manages energy consumption and redundancy.\u003c\/li\u003e\n\u003cli\u003eShutdown sequences prevent thermal shock, freezing, or mechanical stress.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWhether serving a small commercial office, a hospital operating room, a pharmaceutical cleanroom, a hotel, or a hyperscale data center, the underlying operational philosophy remains fundamentally similar: verify safe conditions, establish airflow and water flow, enable cooling or heating sources, modulate capacity according to demand, and shut down in a controlled manner when required.\u003c\/p\u003e\u003cp\u003eThis document presents a generic HVAC system sequence of operation and explains how HVAC systems turn on, operate, respond to changing loads, and turn off.
