Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes an enclosure that is divided by a partition extending between a first panel and a second panel of the enclosure such that the partition defines an outdoor air flow path and a return air flow path through the enclosure. The partition includes an opening extending between the outdoor airflow path and the return airflow path. The HVAC system also includes an energy recovery wheel that translatably extends through the opening and is positioned within the outdoor air flow path and the return air flow path. The energy recovery wheel is disposed within the enclosure at an oblique angle relative to the outdoor air flow path and the return air flow path.

Abstract: 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.
