The present invention provides a system and single controller for receiving
constant and individualized information from a plurality of air control
systems. A single controller is capable of controlling and interacting
with at least two separate air control systems to control an environmental
characteristic, and in the process, reduces the costs associated with the
manufacturing and every day operation of the individual systems. In
addition, the controller is capable of intelligently communicating with
the input and output devices of the system, and particularly with each
individually interfaced appliance, such that the controller can adaptively
control the system through the use of stored historical data.
