Bard part number 8620-240 is an OEM EIFM 2 and 3 ton control replacement kit used on Bard wall-mount HVAC equipment to restore correct economizer ventilation control and system sequencing when the original EIFM control components fail or become unreliable. This kit is intended as a direct service replacement that helps return proper operation of the outdoor air and exhaust functions tied to the EIFM option, improving consistency during occupied ventilation and troubleshooting during maintenance. As with any Bard control update, confirm your unit model and serial number compatibility before ordering, and verify wiring and setup per the applicable Bard installation instructions for your specific EIFM configuration.
* Orders less than $50 may incure a minimum order fee.
