Abstract
Abstract A building automation system comprising: means for conditioning air; means, associated with the air conditioning means, for distributing the conditioned air to at least one space to be conditioned and means for sensing environmental conditions in the at least one space to be conditioned. The building automation system also includes means for managing the operation of the conditioning means, the distributing means, and the sensing means; and means, using wireless two-way transmissions, for operably linking the managing means, the conditioning means, the distributing means, and the sensing means.
