The present disclosure relates to a communication cable for a heating, ventilation, and/or air conditioning (HVAC) system having a set of conductors extending between a first end of the communication cable and a second end of the communication cable, and a cable shield surrounding the plurality of conductors. The cable shield has a first shield connector at the first end of the communication cable and a second shield connector at the second end of the communication cable. The first end is configured to couple to a first controller of the HVAC system, the second end is configured to couple to a second controller of the HVAC system, and the cable shield is configured to electrically couple to a single electrical ground point via one or both of the first and second shield connectors.

HVAC cable grounding systems and methods

A water heating system includes a burner assembly for providing a source of thermal energy to a heat exchanger. A water inlet conduit is coupled to the heat exchanger assembly for supplying fresh water to be heated, and a water exit conduit is coupled to the heat exchanger assembly for delivering the heated water to a point of use. A bypass conduit connects the water exit conduit to the water inlet conduit, and a pump disposed in the bypass conduit circulates at least a portion of the heated water from the water exit conduit to the water inlet conduit. A feed-forward sensor positioned in the water inlet conduit between the heat exchanger assembly and the bypass conduit monitors a parameter of the water entering the heat exchanger assembly, and a processor controls the operation of the of the burner assembly in response to the feed-forward sensor.
