- Economizer Logic Module
The Bard 8602-045 Economizer Logic Module is an OEM control component used to manage economizer operation in compatible Bard wall-mount HVAC systems, processing sensor and enable signals to command free cooling functions and help the unit change over correctly between economizer and mechanical cooling. Replacing a failed logic module can resolve intermittent economizer performance, improper damper operation, or control faults tied to the economizer sequence. Because economizer controls can vary by unit series and ventilation package, confirm compatibility by matching the full part number and checking your Bard unit model and wiring diagram before ordering.
