Description
The Trane WIR04000 Wire Return Sensor Temperature is a wired harness assembly used to carry temperature signals from the return air sensing point to the control module. It transmits resistance-based input from the sensor so the system can adjust heating or cooling operation based on return air conditions. The wiring is designed to maintain stable signal communication between the sensing location and control board under normal operating conditions. Installed between the return air sensor and control circuitry in HVAC systems, it operates as a signal transmission component that supports accurate temperature response and coordinated system response.
