Building HVAC controls are the systems and devices used to regulate the temperature, humidity, and air quality of a building. These controls can be as simple as a single thermostat or as complex as a network of sensors, controllers, and actuators. The purpose of HVAC controls is to ensure that the building’s occupants are comfortable and that the building’s systems are operating efficiently. By controlling the temperature, humidity, and air quality, HVAC controls can reduce energy costs, improve indoor air quality, and extend the life of the building’s HVAC systems. HVAC controls are typically installed by a qualified HVAC technician, who is trained to understand the needs of the building and the occupants, and to select the appropriate components for the job. In addition to selecting the right components, the technician must also ensure that the components are properly installed and that the system is properly calibrated. Properly installed and calibrated HVAC controls can help ensure that the building’s occupants are comfortable and that the building’s systems are operating efficiently.
