Manual Humidifier Control
Figure C – Manual Humidifier Control
90-1237
Your Aprilaire humidifier is controlled by a Manual Humidifier
Control (see
Figure C
). 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 excessive 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.
