Building HVAC Controls

Teach the fundamentals of modern building HVAC controls in a compact system

This system teaches modern HVAC direct digital controls (DDC) of commercial buildings using components from Johnson Controls. Devices from the system communicate over an SA bus or FC bus using the widespread open source BACnet MS/TP protocol. Modern installations use a technology called direct digital control (DDC), a microprocessor-based system that can be programmed for various control sequences. These complex HVAC systems require installation and maintenance technicians to have a strong understanding of their general operation.

Topic coverage

  • Identify/locate sensors, controllers and actuators of a typical air-handling unit (AHU), and define direct digital control
  • Differentiate between the types systems such as CAV and VAV for controlling temperature, humidity and CO2 levels
  • Briefly explain how the various devices of an HVAC system exchange information
  • Connect zone controllers to the simulated AHU, load various scenarios and adjust the signal value of the simulated sensors
  • Access and view status HVAC system information on a SCADA interface from a web browser
