MC5000-B OBSOLETE
- LEAD-LAG CONTROLLER W/ECON SHUTDOWN, B-ALARM BOARD
The Bard MC5000-B is an OEM lead lag controller assembly with economizer shutdown and the B alarm board configuration, used to coordinate redundant Bard HVAC units by staging operation and managing fault and status alarm outputs for critical cooling applications. This controller is designed to maintain orderly rotation and response logic between paired systems, helping keep telecom and equipment shelter cooling stable while providing the alarm functions associated with the -B alarm board. If you are replacing a failed controller or restoring proper lead lag operation after service work, match the part number MC5000-B exactly and verify wiring and sensor compatibility per the Bard controller instructions for your installation.
