This Air Switch Kit resolves the issue of the air conditioning fan not running constantly, such as in situations where the fan turns off when the thermostat temperature is reached (most residential systems do this). This will ensure that the scent machine only dispenses fragrance when the air conditioning fan is running. The Scent Machine – Professional includes the wiring to
connect an air switch or other devices to interrupt power to the fragrance oil pump, but this Air Switch Kit is sold separately.
