Communications system, a hvac system employing the same and a method of manufacturing a component for the hvac system

Abstract

In one aspect, the disclosure provides an HVAC system. In one embodiment, the HVAC system includes: (1) an air handler configured to condition and circulate air for the HVAC system, and (2) an air handler controller for the HVAC system configured to control operation of the air handler, the air handler controller including interface circuitry having a predetermined coupling impedance and configured to couple the air handler controller to components of the HVAC system via a communications network of the HVAC system, wherein a total of the predetermined coupling impedance and an end node coupling impedance at each of the components is substantially a defined maximum loading impedance for the communications network and wherein the end node coupling impedance of one of said plurality of end nodes is determined based on said predetermined coupling impedance and end node coupling impedances of remaining ones of the plurality of end nodes.

Dependencies are inferred from the claim text.
