3.0 CONTROLS (CONT’D)
Location: Located in the busiest area of the house.
Purpose: To adjust air supply and select desired indoor humidity level.
Adjusting the AIR SUPPLY CONTROL:
a) Select speed MIN. or MAX. using switch A (as shown on diagram).
• Select speed MIN. (minimum speed) for normal daily operation (24 hours a day all year round).
• Select MAX. (maximum speed) for excess pollutants and humidity (parties, odors, smoke, etc.)
b) To turn the unit off, place selector at the OFF position. However, if optional auxiliary controls
are used, they will still be active.
Adjusting the HUMIDITY CONTROL:
Setting during the summer months:
Normally, there is no condensation on your windows during this period which, therefore, eliminates the need of the humidity control.
Set knob B to SUMMER position during this period.
Setting during the fall, winter and spring months:
• METHOD 1 (fast and simple for new users):
a) Determine approximately the outside daytime temperature.
b) Set knob B to this temperature.
NOTE: Continue using this method for about a month before trying Method 2 suggested below.
• METHOD 2 (more precise adjustment):
Use METHOD 2 (steps a to f below) if there is condensation on your windows after using METHOD 1 for at least
1 month. As ventilation needs vary from one house to another (depending on cooking habits, frequency of showers,
washing, window design, etc.), an adjustment based on outside temperature may not adequately solve the condensation
problem in your house.
a) Select speed MIN.
b) Turn knob B clockwise until you hear a click.
c) Turn knob B a notch below the click.
d) 12 to 24 hours later, check if there is still condensation on the windows.
e) If there is, repeat steps b, c, d above (until desired results are obtained).
f) Compare the two values: the one obtained with METHOD 1 and the other with METHOD 2. Use the variance for
future reference. For example, if there is a 3-degree variance, you can conclude that, for your house, an adjusment
of 3 degrees below the outside temperature is required for optimum condensation control.
It is possible (and normal) to experience condensation on your windows when drastic changes in temperature occur (e.g. -5°C
[23°F] to -20°C [-4°F]). In that case, we suggest waiting a few days to allow the situation to stabilize.
