8602-025 OBSOLETE
- Enthalpy Control
Bard 8602-025 is an OEM enthalpy control component used with Bard economizer ventilation systems to help the unit decide when outdoor air conditions are suitable for free cooling based on temperature and humidity rather than temperature alone. In wall-mounted Bard applications equipped with an enthalpy-capable economizer control, this part supports stable economizer changeover and proper damper operation by providing the correct enthalpy-based input so the system can economize when conditions are favorable and lock out economizer operation when they are not. For best results, confirm compatibility by matching the Bard part number 8602-025 to your unit model and the economizer control sequence shown in the Bard documentation before ordering.
