MC4001-AC OBSOLETE
- BARD LEAD LAG CONTROLLER W/BASE ALARM & ETHERNET BOARD
The Bard MC4001-AC is an OEM solid state dual unit lead lag controller package designed to coordinate two Bard wall mount air conditioners in telecom and other critical cooling applications by alternating lead duty, balancing runtime, and maintaining stable temperature control. This version includes the base alarm board and the Ethernet communication board so you can integrate remote monitoring while still keeping local alarm outputs available for common site alarm requirements. Built to Bard specifications for compatibility with MC4001 Series control strategies and wiring practices, the MC4001-AC is the correct choice when you need a direct replacement controller assembly to restore reliable staging, changeover, and alarm reporting without field improvisation.
