Operation - Fantech SHR 1504 Operation Manual

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 with the stale air that is being exhausted.
Fantech HRV'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 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. If the Intellitek series 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.
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 dehu-
midistat may help give greater control over the inside environment.
