It is a single-pole normally open electromechanical relay that has a 24-volt coil, which closes its contact when energized to allow current to pass to a load in HVAC systems. It is connected to thermostats, control boards, and contactors. This relay aids in switching control loads and also in the coordination of compressors, fans and other objects in air handlers, rooftop units, furnaces, and packaged equipment.
