Learn the basics of HVAC Controls. What are Analog and Binary Inputs and Outputs used for? See how a Fan Coil System, VAV System and Garage Carbon Monoxide Control System Works. These HVAC systems are used to control temperature, pressure, humidity, flow, and air quality. In this video we’ll show you how these HVAC systems use various controls to respond to the needs of the environments that they seek to control.
