OPERATION
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 con-
tinuous ventilation with high speed override is recommended.
A Heat Recovery Ventilator (HRV) 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 HRV will help in cooling the incoming fresh air
using the stale air that is being exhausted.
Fantech HRVs are designed to run continously or intermittently, giving the homeowner complete control over their air quality.
Continuous low speed ventilation is recommended, which will help eliminate carbon dioxide, VOCs 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 HRV.

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.
Summer:
The air is sometimes hot and humid. To stop the warm humid air from entering, set the
dehumidistat at its highest level. If the EDF5 controller is installed, the air exchanger can
be set to cycle the unit on and off as desired from that wall control. However, continuous
ventilation is recommended.
Spring:
Temperatures are more moderate and become warmer each day. To keep the humidity and
temperature uniform, set the dehumidistat higher (if installed). You may also switch the
HRV to standby mode if desired.
