Change the knob settings as outdoor
temperature changes occur.
WARNING: Do not leave the knob in the in the
“TEST” position above “+20” or the humidifier will run
constantly.
If sweating of windows or walls occurs:
1. Check the indicator setting. The indicator should
point to the number that represents the lowest
expected 24-hour outdoor temperature. Wait 24
hours before changing the indicator setting.
2. If the indicator setting in Step 1 is correct, and
conditions have not changed, rotate the knob
back and forth from the “TEST” to minimum
humidity setting. If the humidifier goes on and
off, the control is operating properly.
3. Remember, to increase the indoor relative
humidity, turn the indicator clockwise ^ .
To decrease indoor relative humidity, turn
counter-clockwise ^ .
NOTE: Because of differences in home construction,
the number of occupants, and living habits in some
homes, when the anticipated 24-hour lowest outdoor
temperature is,for example, +10°F, your ideal humidi­
stat setting may be the low position.
