• COMMUNICATION BOARD KIT for MC4001

The Bard CB5000 is an OEM communication board kit used with Bard MC4001 series lead/lag HVAC controllers to provide Ethernet-based remote access for monitoring and adjusting controller functions from a networked computer. This replacement board is intended to restore reliable connectivity for viewing system status, alarms, temperatures, and setpoints where the controller is installed, making it a practical fix when the existing communication interface is damaged, unresponsive, or missing. Confirm compatibility with your specific MC4001 controller configuration and follow the Bard installation instructions for network setup and internal controller connections.
