if the knob
B
is set above the click, the unit
will exchange in low speed with the
outside and if it is set below the click, the
unit will exchange on high speed with the
outside until the desired humidity level has
been reached.
• When “MAX.” (maximum speed) is selected,
the unit will exchange on high speed with
the outside either if he knob
B
is set below

active.
A
DJUSTING
THE
CONDENSATION CONTROL
Setting during the summer months:
Normally there is no condensation on your windows during this period which therefore
eliminates the need of the condensation control for a few months. Set knob
B
at the
“SUMMER’’ position during this period.
Setting during the fall, winter and spring months:
1)
Determine the humidity level in your house (bring the knob
B
counterclockwise to
-20°C, then bring it back clockwise slowly until you hear a “click”).
2)
Set knob
B
a notch under this temperature level or “click”.
NOTES:
1. Do not select a temperature below -20°C. This could lead to excessive dryness
in the air causing discomfort for the occupants.
2. When the humidity level is high, the unit automatically operates at maximum
speed. If you change the setting of your “AIR SUPPLY” knob (
B
) at that time, it
will remain at maximum speed until the humidity level is reduced, and then
switch to the desired setting.
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] within few
hours). In that case, we suggest waiting a few days to allow the situation to stabilize.
