To avoid window
condensation:
• It is not necessary to
change the humidity
control every day. Monitor
the average weekly
temperature or
experiment with various
settings until you find a
level that is comfortable
for you. Adjust the
control when needed.
•
A dehumidistat is ideal
for use in energy
efficient houses where
indoor humidity (during
the heating season) is
higher than outdoor
levels. High humidity is a
major cause of structure
damage and IAQ
problems such as mold
and mildew.
