Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a heat pump having a housing. The HVAC system also includes an energy recovery ventilator (ERV) or heat recover ventilator (HRV) integrated with the heat pump such that an access panel to the ERV or HRV faces outwardly from the housing of the heat pump, and such that the access panel is accessible at an outer boundary of the housing.

Abstract: A method and system for testing a remote I/O sub-assembly. The method including: allocating source memory, destination memory and DMA queue memory location in a memory of the remote I/O sub-assembly; writing a pattern of test data into the source memory location; writing a set of descriptors simulating data transfer commands into the DMA queue memory location; wrapping a first remote I/O port of the remote I/O sub-assembly to a second remote I/O port of the remote I/O sub-assembly with a remote I/O wrap cable; (e) configuring a DMA engine of the remote I/O sub-assembly to point to the DMA queue memory location and to the first and second remote I/O ports; and loading each descriptor of the set of descriptors into the DMA engine and transferring data from the source memory location to the destination memory location based on the descriptors.
