The Bard HVAC MC5300-BC Lead/Lag Wall-Mount Controller is equipment that is used to control the operation of several HVAC systems. It also serves the purpose of a lead/lag switch, which controls the cycling of units in a staggered manner. This avoids the occurrence of two start-ups at once, lessens the demand on the electrical system, and saves on equipment. Ideal for up to three units, the controller optimizes the system performance, prolongs the life of the equipment, and helps to save energy and cost. It is usually applied to rooftop units, chillers and other types of HVAC systems that are best run in stages.
