Trane BAYENTH005A Enthalpy Kit 319852-301 this specific thermal expansion valveThe Trane BAYENTH005A Enthalpy Kit is a field installed OEM component engineered for ReliaTel controlled rooftop units to provide precise enthalpy based economizer control. By integrating both dry bulb temperature and relative humidity sensors, this kit allows the system to calculate the total heat content (enthalpy) of the outside air. This data is critical for determining when outdoor air is more suitable for "free cooling" than mechanical
