Operation

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.
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:
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.
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.
