The digital readout on the automatic control displays the RH level inside the cold air return duct. RH is a measure of the amount of moisture in the air as a percentage of what the air can hold. Warm air can hold more moisture than cold air can. This reading will accurately indicate the RH in the living space when the HVAC blower is operating. Once the HVAC blower stops, the readout will not change. The control has lights which indicate humidifier operation, when the water panel needs to be replaced and when service is required. See “Operating Instructions” for more information. There are many humidifiers on the market. They all add moisture… with varying degrees of efficiency. None, however, offer the features, design, and performance incorporated into your new Aprilaire humidifier. -2--3- OPERATINGINSTRUCTIONS–MODELS400A,500A,600A&700AOPERATINGINSTRUCTIONS–MODELS400A,500A,600A&700A The Automatic Digital Humidifier Control offers two modes of operation, Automatic or Manual. An explanation of both modes follows. (See Figure A on page 5 for Automatic Mode. See Figure B on page 6 for Manual Mode.) When in the Automatic Mode, this system offers the following benefits: • You will always receive the optimum amount of humidity so that your home and its furnishings are always protected from the damaging effects of excess condensation or low humidity during the heating season. The Control automatically adjusts your home’s RH based on the outdoor temperature, increasing the time maximum comfort is maintained. • Simple operation with few adjustments. The Control eliminates the need to manually adjust the control when outdoor temperature changes. It also eliminates the need to turn the dial setting to “OFF” during the summer season. AUTOMATIC DIGITAL HUMIDIFIER CONTROL INDICATOR LIGHTS Call Dealer for Service: The red light indicates that the humidifier is not operating normally and that service is required. Change Water Panel: The yellow light indicates that it is time to change the Water Panel in the humidifier. Humidifier On: The green light indicates that the humidifier is operating normally. AUTOMATIC MODE FIGUREA–AutomaticMode90-1235 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. During the next 24-48 hours it may be necessary to adjust the dial for more or less humidity, depending on your personal comfort and home’s requirements. Refer to TABLE 3 – Operation Guide. 2. During the coldest portion of the first heating season, minor adjustments may be necessary. This is dependent upon your home’s construction. Refer to TABLE 3 – Operation Guide. The RH in your home will now be accurately controlled to meet your needs and should not need further adjustment during future heating seasons. Make note of the dial setting in the event you temporarily move the knob to “OFF” when performing annual maintenance of your Aprilaire humidifier. -4--5- MANUAL MODE FIGUREB–ManualMode90-1236ManualModeLabelandResistor When installed in the Manual Mode (see Figure B), it is important to anticipate a drop in outdoor temperature and reduce the setting accordingly to avoid excessive condensation. For example, with an outdoor temperature of 20°F the correct setting will be 35% RH. If the temperature is expected to fall to 0°F that evening, then merely reduce the setting to 25% several hours prior to the temperature change. See Table1for the recommended settings.
