Step 4. Operating the Controls
Where you set your desired humidity levels depends on your personal comfort level, outside temperature and inside temperature. A starting set point of 30% - 40% ROOM humidity is recommended but there may be conditions that require a different setting.
IMPORTANT: Water damage may result if condensation starts to form on windows or walls. Humidity SET point should be lowered until condensation no longer forms. We recommend room humidity levels do not exceed 50%.
