Automatic Digital and Manual Humidifier Control Models 60, 62 & 4655 Operating Instructions INSTALLER: Please leave this Operation Manual with the homeowner.
YOUR HUMIDIFIER OPERATING INSTRUCTIONS Your humidifier is controlled by either an Automatic Digital Humidifier Control, or a Manual Humidifier Control. The Automatic Digital Humidifier Control offers two modes of operation, Automatic or Manual. When in the Automatic Mode, this system offers the following benefits: • You will receive the optimum amount of humidity so that your home and its furnishings are protected from the damaging effects of excess condensation or low humidity during the heating season.
AUTOMATIC MODE (Manual Mode – see page 5) MANUAL MODE (Automatic Mode – see page 4) Figure B – Manual Mode Figure A – Automatic Mode 90-1235B Your Aprilaire Humidifier Control is installed in the cold air return duct. During the first heating season, your Humidifier Control needs to be set initially to match your home’s condition. Please follow these steps when adjusting your control (refer to Figure A). 1. Turn the dial setting knob to “5”, which is within the normal range.
See Table 1 for the recommended settings. These settings, which are based on years of research, represent a compromise between humidity levels that would be most desirable for comfort and humidity levels that are suitable for protection of your home and to avoid condensation on your windows. For example, a wintertime indoor humidity of 50% may be considered ideal for comfort, but unfortunately, it probably would result in condensation, which can cause damage to your home.
ADDITIONAL INFORMATION TABLE 3 – Operation Guide Your humidifier is a precision system that will accurately maintain the humidity in your home. For every 2°F change in outdoor temperature, the Digital Humidifier Control will automatically adjust the indoor RH by 1%. The Digital Humidifier Control will accurately control the humidity in your home to a maximum of 45%. The humidity values in Table 2 are targets based on outdoor temperature and the Digital Humidifier Control setting.
