TABLE 3 – Outdoor-Indoor Relative Humidity - 6 - Manual Mode: (Automatic Mode – see pg 4) Your Aprilaire Humidifier is controlled by a Humidifier Control installed either in the living area or in the cold air return. It is important to anticipate a drop in outdoor temperature and reduce the setting accordingly to avoid excessive condensation.
