Operation

A Air Exchangers (AEV) is designed to bring fresh air into a building while exhausting an equal amount of stale air. During the winter months, the
incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors. During summer months
when the indoor space is air conditioned, the AEV will help in cooling the incoming fresh air with the stale air that is being exhausted.
Our AEV's are designed to run continuous or on intermittent, giving the homeowner complete control over their air quality. Continuous low speed
ventilation is recommended, which will help eliminate carbon dioxide, voc's and other gases as well as freshen up the home. Intermittent high speed
ventilation can be obtained through a variety of optional remote controls found in this manual. Below are some examples of seasonal operation of an
AEV.
Winter:
Humidity control is very important during the winter
months. This is when problems will be most
apparent since condensation on the windows will
often occur. The colder the outside temperature, the
greater the risk of condensation in the home. The
average relative humidity should be maintained
between 30-60% to avoid condensation. Low speed
continuous ventilation with high speed override is
recommended.
Spring:
warmer each day. To keep the humidity and
temperature uniform, set the dehumidistat higher (if
installed). You may also switch the AEV to standby
mode if desired.

Optional control

To avoid window condensation:
• It is not necessary to change
the humidity control every
day. Monitor the average
weekly temperature or
experiment with various
settings until you find a level
that is comfortable for you.
• Adjust the control when
needed.
Summer:
The air is sometimes hot and humid. To stop the
warm humid air from entering, set the dehumidistat
at its highest level.
Fall:
Rain and rapid temperature changes make it difficult
to control the internal humidity level and may result in
condensation on the windows. A remote dehumidistat
may help give greater control over the inside
environment.
Dehumidistat I
The wall mount dehumidistat monitors the humidity level in the area it is
installed. When the humidity level rises above the desired set-point, the
AEV will activate to high speed/override mode. Once the humidity level
returns to desired condition, the unit will return to the normal mode.
2 low voltage wires required for operation.
