HVAC control assemblies, and corresponding methods of determining equipment wiring harness connections

Abstract:

Exemplary embodiments are provided of HVAC control assemblies. In an exemplary embodiment, an HVAC control assembly includes an HVAC control board, a first interface connector, and a second interface connector. The first interface connector and the second interface connector each include multiple pins adapted for connection to an equipment wiring harness. The assembly also includes an electrical conductor connected between at least one of the multiple pins of the first interface connector and at least one of the multiple pins of the second interface connector, and an HVAC controller configured to determine whether an equipment wiring harness is connected to the first interface connector or the second interface connector based on a state of at least one of the multiple pins connected to the electrical conductor. Example methods of determining an equipment wiring harness connection in an HVAC control assembly are also disclosed.
