Trane WIR3345 Air Temperature Wire Harness 16"

The Trane WIR3345 16” air temperature wire harness is an essential part of measuring and controlling air temperature in HVAC systems. It conveys temperature information of a limit switch to the control board of the system. This data assists the control board keep specific temperatures for comfort by addressing chants which include use of the heater or ac. Limit switches are normally mounted in the air ducts or in any other specific location in the HVAC equipment. It has a temperature sensitive component that produces an electrical signal when a particular temperature is attained. The wire harness then transmits this signal to the control board where the signal is decoded and an appropriate action taken.
