HVAC computer control systems are a type of technology used to control the heating, ventilation, and air conditioning (HVAC) systems in a building. These systems are designed to provide a comfortable and safe environment for occupants, while also helping to reduce energy costs. HVAC computer control systems use a variety of sensors, controllers, and actuators to monitor and control the temperature, humidity, and air quality of a building. The system can be programmed to respond to changes in the environment, such as when the temperature outside changes, or when the humidity level rises. The system can also be programmed to turn on or off certain HVAC components, such as the air conditioner or furnace, at certain times of the day. By using a computer control system, buildings can maintain a comfortable and safe environment while also reducing energy costs.
