Reznor 271994 Sensor R-407A Choosing a PCBBF125S HVAC controlThe Reznor 271994 Averaging Temperature Sensor is a critical OEM replacement part engineered for precise thermal feedback in mixed air and cooling coil applications. Featuring a 36 inch length, this YD B type sensor is designed to mitigate the effects of stratified airflow by measuring the temperature across a wider cross section of the duct. This ensures the HVAC controller receives an accurate average reading rather than a localized "hot" or "cold"
