Bard ECON-WD2-4 is a field installed, low leakage economizer with exhaust designed for compatible Bard wall mount air conditioners and heat pumps, providing full flow ventilation up to 100 percent outside air when conditions allow. This OEM assembly uses a JADE controller with outdoor enthalpy sensing and a mixed air sensor to modulate the dampers for reliable free cooling, stable supply air control, and code required minimum ventilation when an occupied signal is present. It is commonly applied on W and J series wall mount units in the 1.5 to 3 ton range, and it is a dependable choice when you need a direct fit Bard economizer package that restores proper outdoor air and exhaust function without guesswork on field adaptations.
