Window Protection is set on a scale from 1–10. A setting
of 1 represents poorly insulated windows and a setting of
10 represents well insulated windows. A lower number
automatically reduces the humidity to help prevent frost
or condensation on your windows. Use a higher number
if indoor air seems too dry. To prevent frost/condensation
on your windows during cold outdoor temperatures,
poorly insulated windows require a lower Window Pro-
tection setting, which will limit how much your humidifier
can run.
7.
After you set the Window Protection setting, check for
frost/condensation on your windows in the morning. If
frost/condensation is present, adjust the Window Protec-
tion setting to the next lowest number and check for frost/
condensation on your windows the next morning. Con-
tinue to adjust the Window Protection setting to a lower
number until frost/condensation is no longer present.
NOTE: The thermostat will not run the humidifier when
the indoor humidity has reached the “Window
Limit” that is displayed on the screen.
NOTE: Window Protection is available only if an outdoor
air sensor is installed.
