Description
The Trane WIR03423 Wiring Harness for Return Air Temperature and Humidity Sensors is an electrical connection assembly HVAC systems to link return air with the main control board. It carries low-voltage signals that allow the system to monitor return air conditions such as temperature for accurate environmental control. This is typically installed in air handling units and rooftop systems where sensor feedback is required for regulating cooling, heating, and ventilation cycles. It supports proper system operation by ensuring data transmission between the sensing component and control logic.
