HVAC controls and building automation parts (also known as BAS or DDC components) are the controllers, actuators, sensors, and valves that regulate heating, ventilation, air conditioning, and lighting systems in commercial and institutional buildings. Network controllers and direct digital control (DDC) modules process temperature, pressure, and flow readings from field sensors and command damper and valve actuators to maintain setpoints. Found in office buildings, hospitals, schools, and industrial facilities, these components are essential for occupant comfort, energy efficiency, and reliable operation of building mechanical systems.
