Fig. 111.
2. Select Auto.
3. Move the slider bar to select humidity level.
Fig. 112.
4. Touch More Settings if frost or condensation appears on
the windows. Use a lower number to prevent frost or con-
densation. Use a higher number if indoor air is too dry.
Window Protection limits the amount of humidity to pre-
vent frost or condensation on windows. See notes below.
Fig. 113.
5. Touch Done to save your settings. Touch Cancel to
ignore changes.
6. 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.
