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 1 – Operation Guide".
2. During the coldest portion of the first heating season, minor adjustments
may be necessary. This is dependent upon your individual home
construction, refer to "TABLE 1 – Operation Guide".

Your Automatic Humidifier, is a high precision system that will accurately
maintain the relative humidity in your home. For every 1°F change in outdoor
™ or
temperature, the control will automatically adjust the indoor relative humidity
(RH) by 1/2%. If you would like to determine the RH in your home, follow
these steps:
1. Determine the outdoor temperature.
2. Activate the furnace blower by setting your thermostat fan switch to the
"On" position, or setting your thermostat to a higher temperature.
3. Turn the control dial setting to the "Off" position. Then, slowly turn the
dial clockwise until you hear the solenoid valve "click on." Next, slowly
turn the dial counter-clockwise until you hear the solenoid valve "click
off." 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.
TABLE 2 – % Relative Humidity Guide
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%.
The HumidiTrac
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.
