enabling up to 10 damper motors to be linked via modular cords on a single zone

reducing the risk of premature high-limit trips

Field-made wiring often lacks the proper gauge and terminal crimp integrity required for UL-rated system performance

it ensures seamless integration with existing burner manifolds
