Bard 8620-221 - EIFM Relay Kit
Bard part number 8620-221 is an OEM EIFM relay kit used with MC4000 lead lag controllers and CB4000 communication boards when interfacing with older style EIFM economizers, helping the controller reliably recognize and manage economizer operation as intended. This relay kit is a practical fix when retrofitting or servicing Bard wall mount systems that use economizer free cooling controls, since the relay provides the proper switching interface the controller expects for accurate status and command operation. As a genuine Bard electrical control component, 8620-221 is built for correct fit and dependable field performance, and we recommend confirming economizer style and controller wiring against the Bard installation manual before ordering to ensure compatibility.
