MANUAL HUMIDIFIER CONTROL
FIGURE 3 – MANUAL HUMIDIFIER CONTROL
Your AprilAire humidifier is controlled by a Manual
Humidifier Control (see FIGURE 3). The Manual
Humidifier Control is installed either in the cold air
return duct or on an interior wall of the home. With the
Manual Humidifier Control, it is important to anticipate
a drop in outdoor temperature and reduce the setting
accordingly to avoid excess condensation, just as with
the Digital Humidifier Control installed in Manual Mode
(see page 6).
To determine the indoor RH, slowly turn the knob
clockwise and counterclockwise and listen for 2 clicks.
The indoor RH is within the range of the 2 clicks. See
TABLE 2 on page 9.
