DJUSTING
HUMIDITY CONTROL
Setting during the summer months:
During this period, unless being afflicted with breathing problems, using the
humidity control is unnecessary. Set the slide switch to ‘’OFF’’. (Do not
exchange in day time; exchange at night time, if cool outside, or if it is not
raining.)
Setting during the fall, winter and spring months:
(When condensation appears on windows)
1) Determine the humidity level in your house (bring the knob counterclockwise
to its maximum position, then bring it back clockwise slowly until you hear
a “click”).
2) Set the knob to one line under this temperature level or “click”.
It is possible (and normal) to experience condensation on your windows
when drastic changes in temperature happen (for example: -5°C [23°F]
to -20°C [-4°F]). In that case, we suggest waiting a few days to allow the
situation to stabilize.
CAUTION
Do not select a temperature below -20°C (-4°F). This could lead to
excessive dryness in the air causing discomfort for the occupants.
