Vav Box Control can be defined as an automated system that regulates air temperature and air flow within a heating, ventilation, and air conditioning (HVAC) system. The control system adjusts the output of each individual Vav box or zone to maintain the desired temperature.. It does this by adjusting the fan speed and mixing valve settings in order to modulate airflow and transfer heat/cooling as needed to maintain the setpoint in each zone. This helps to create a comfortable and efficient workplace environment while saving energy. With its ability to independently manage each zone, Vav Box Control is essential for businesses that need to tailor their climate zones to ensure the optimum environment for their staff and customers.
