Resumen del manual
At this point, make note of the dial setting. 4. Locate your dial setting on Table 2. Follow the dial setting to the right until it intersects with the current outdoor temperature. This is the relative humidity in your home under existing conditions. 5. Return the thermostat and the Humidifier Control to their original settings. The Automatic Humidifier will accurately control the humidity in your home to a maximum of 45% RH and a minimum of 10% RH. The values of outdoor temperature and dial settings may fall in between or outside of the listed values in Table 2. In these cases, you can only approximate your home’s actual indoor RH. The relative humidity 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 when performing annual maintenance of the Aprilaire Humidifier.

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° the correct setting will be 35% relative humidity. If the temperature is expected to fall to 0° that evening, then merely reduce the setting to 25% several hours prior to the temperature change. The recommended settings on the Humidifier Control are based on years of research and experience (see Table 3). These settings represent a compromise between RH levels that would be most desirable for comfort reasons and humidity levels that are suitable for protection of your home and to avoid condensation on your windows. For example, a wintertime indoor RH of 50% may be considered ideal, but unfortunately, it probably would result in damage to your home. Observance of the recommended RH levels on your Humidifier Control, therefore, is an important safeguard. Condensation of water on inside windows in the form of fogging or frost is usually an indication of too much relative humidity. This same condensation can take place in other areas in your home with the possibility of damage resulting. As an example, if the outdoor temperature is 20°F, and, following step 3, the humidifier turns off at “5” on the dial range, then the RH in your home is 35%. -10 0 10 20 30 40 1 10 10 10 15 20 25 2 10 10 15 20 25 30 3 10 15 20 25 30 35 4 15 20 25 30 35 40 5 20 25 30 35 40 45 6 25 30 35 40 45 45 7 30 35 40 45 45 45 Outdoor Temperature (°F) Dial Setting TABLE 2 – % Relative Humidity Guide - 7 - Your Aprilaire Humidifier Control is a precision instrument that can be used to determine the RH accurately in your home during the winter. To do this, follow these steps: 1. Activate the furnace blower by setting your thermostat to a higher temperature. 2. Turn the control dial setting to the “Off” position. Then, slowly turn the dial clockwise until you hear the solenoid valve on the humidifier “click on.” Next, slowly turn the dial counter clockwise until you hear the solenoid valve “click off.” At this point, read the RH on the dial. This will be very close to the actual RH in your home. (See Figure B) To check the humidifier operation, set the knob to “Test/Reset”, make sure that the water saddle valve is open and that there is electricity to the unit. The furnace blower motor must be operating and the furnace calling for heat for the Aprilaire Humidifier to function. Note: Turning the knob to “Test/Reset” resets the “Change Water Panel” internal timer. After the humidifier has operated for one minute and water is entering the unit and coming out at the drain, reduce the humidistat setting to the recommended inside relative humidity, depending on the outside temperature. DO NOT LEAVE IN TEST MODE AS HUMIDIFIER WILL NOT OPERATE. Follow the suggested settings prior to a drop in the outside temperature.

Whether to use available tap water, even though it may be quite hard, or chemically softened water, is a common concern to homeowners when installing a humidifier. Water used in homes contains varying amounts of minerals. The residue remaining as a result of hard water evaporation is primarily calcium and magnesium components and is usually quite hard, scaly, and dense. Residue from softened water tends to be soft and fluffy and has a greater volume than hard water scale. The service life of a Water Panel evaporator may be extended by using hard water. In either case, the Water Panel evaporator is usuall...
