Device employable in different circuit configurations using parallel wiring harnesses, a HVAC system employing the device and a method of manufacturing a HVAC unit

摘要

A HVAC unit manufacturing method and a HVAC system are disclosed herein. In one embodiment, the HVAC system includes: a controller having control board terminals, a parallel wiring harness having a first and a second connection header, the first connection header coupled to the control board terminals, and a switch having terminals. The terminals of the switch including: a pair of functional terminals configured to indicate a status of the switch and a pair of jumpered terminals independent of the pair of functional terminals and internally connected together within the switch, wherein designated combinations of the terminals indicate a circuit configuration for employing the switch in the HVAC system with each of the terminals having a particular design that dictates a specific corresponding connection header be used for each of the designated combinations, wherein a single one of the designated combinations of the terminals corresponds to the second connection header.

主权项

1. A method of manufacturing an HVAC unit, comprising:
connecting a first device to a second device having multiple terminals employing a first parallel wiring harness, said multiple terminals including a pair of functional terminals connected across a contact of said second device and a pair of jumpered terminals independent of said pair of functional terminals and internally connected together, wherein designated combinations of said terminals indicate a circuit configuration for said electrical device with each of said terminals having a particular design that dictates a specific corresponding connection header be used for each of said designated combinations; and connecting said second device to a third device employing a second parallel wiring harness, wherein said third device is a same device as said second device and said first parallel wiring harness has a first connection header configured to connect to one of said designated combinations to implement a particular circuit configuration.
