The sensor automatically turns on the HVAC fan to measure the relative humidity inside the ducts and in all rooms of the house. The humidifier turns on as soon as the measured humidity drops below the set point. The humidifier is an equipment too often neglected but so important. In winter, heating dries out the air. The result is discomfort such as skin irritation, dry cough, static electricity and sometimes even nosebleeds, not to mention damage to furniture and woodwork. Adding an Aprilaire® 400 humidifier helps prevent all this.
