Bard MC4002-A - Dual unit lead lag controller
The Bard MC4002-A is an OEM dual unit lead lag controller that sequences two Bard wall mounted air conditioners so runtime is shared evenly while still bringing on additional cooling stages as demand increases. Supplied with Alarm Board A, it provides dry contact alarm outputs and clear front panel status indication to support remote monitoring for critical applications like telecom shelters and equipment rooms. This controller is designed to work with systems that may use economizers, two stage or dual compressor cooling, and can be configured for heat pump operation, helping restore proper staging, rotation, and alarm reporting when replacing a failed or obsolete controller.
