Résumé

Stable control of an HVAC system can only be achieved when the number of controlled variables are less than or equal to the degrees of freedom (DOF), which represents the maximum number of variables in the control system that can be manipulated by it. In complex HVAC applications, the number of points in a system, such as an air handler control sequence, can exceed 100. Therefore, understanding the DOF in such a system is essential in realizing a stable control sequence.
