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.
