Abstract
According to one embodiment of the invention, a method for regulating temperature in a system comprises receiving, at a building management system, information concerning a degree of opening of a plurality of control valves. Each of the plurality of control valves is associated with at least one terminal that is in communication with a supply header line of a system, and is operable to open or close according to its own logic based on the demand of the associated terminal or terminals. A determination is made, based on the degree of opening of the plurality of control valves, as to whether changes need to be made to the operating parameters of production equipment of the system. The changes to the production equipment operation of the system are operable to change at least one parameter of a fluid being supplied to the supply header line of the system. An initiation of changes is made if it is determined that the change needs to be made. The changes in the production equipment yield a difference in the at least one parameter of the fluid.
