MANUAL MODE (AUTOMATIC MODE – SEE PAGE 5)
FIGURE 2 – MANUAL MODE
When the humidistat is in Manual Mode (see FIGURE 2
– internal switch in the MAN position and M in the
display), it is important to anticipate a drop in outdoor
temperature and reduce the setting accordingly to
avoid excess 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, reduce the setting
to 25% several hours prior to the temperature change.
See TABLE 1 for the recommended settings. These
settings represent a compromise between humidity
levels within the range of comfort and protection
from window condensation. For example, a range of
40-60% indoor humidity in wintertime may be ideal for
comfort, but would result in damaging condensation.
Thus, observing recommended humidity levels on
the humidifier control is important. Condensation on
the inside surface of windows in the form of fogging
or frost is indicative of over-humidification. This same
condensation can occur in other areas of the home,
resulting in damage.

WATER PANEL CHANGE INDICATOR (MODEL 60 ONLY)
The control keeps track of humidifier operation time.
The yellow Change Water Panel light flashes after
a preset amount of running time has elapsed. This
running time is preset by the installer based on the
humidifier model and water hardness.
Refer to the ANNUAL MAINTENANCE section for
instructions on changing the water panel or call your
heating and air conditioning dealer for service. After
the water panel is replaced, turn the control knob past
7 to the Test/Reset position. It will click into position.
Leave it there until the green Humidifier On light
flashes, to reset the water panel change timer.
TEST/RESET
The Test/Reset setting allows the humidifier operation
to be checked even if there is no call for humidity. See
CHECK THE HUMIDIFIER OPERATION on page 8.
