Figure B – Manual Mode
When installed in the Manual Mode (see
Figure B
– internal
switch in “MAN” position and “M” in the display), it is important
to anticipate a drop in outdoor temperature and reduce the
setting accordingly to avoid excessive condensation. For
example, with an outdoor temperature of 20°F the correct setting
will be 35%. If the temperature is expected to fall to 0°F, then
merely reduce the setting to 25% several hours prior to the
temperature change.

MANUAL MODE (Automatic Mode – see page 5)
See
Table 1
for the recommended settings. These settings,
which are based on years of research, represent a compromise
between humidity levels that would be most desirable for
comfort and humidity levels that are suitable for protection of
your home and to avoid condensation on your windows. For
example, a wintertime indoor humidity of 50% may be
considered ideal for comfort, but unfortunately, it probably would
result in condensation, which can cause damage to your home.
Observing the recommended humidity levels on your Humidifier
Control is an important safeguard. Condensation of water on the
inside surface of windows in the form of fogging or frost is
usually an indication of too much humidity. This same
condensation can occur in other areas in your home, possibly
resulting in damage.
