Process and apparatus for individual adjustment of an operating parameter of a plurality of environmental control devices through a global computer network

Abstract

An apparatus and process for individual adjustment of an operating parameter of a plurality of environmental control devices, such as VAV devices (,) in an HVAC system. The process includes the step of connecting at least one of computers (,) for input of a parameter control set point based signal and a unique VA device identifying signal through an Internet website (,) to the plurality of HVAC devices (,). The computer (,) is, for example, connected to the VAV devices (,) such that the computer (,) can be used to adjust the temperature set point of only one of the plurality of VAV devices (,), most typically the device located in the same space (,) as the communicating computer (,). Such computer (,) can be wired or wireless, and use the global computer network website (,) to connect to the VAV devices (,) through a building computer (,) and local area network (,). In the preferred form, the computers (,) are also capable of retrieving the current temperature set point from the VAV device (,) and the current room air temperature proximate the VAV device (,), outputting or displaying them on a computer output or display device, and thereafter adjusting the temperature set point for the environmental control device, for example, by using graphical interface software.
