Automatic Summer Bypass

The Summer Bypass includes a damper assembly which allows the supply fresh outside air directly into the home without going through the heat exchange system. Heat will not be recovered from the warmer inside air of the home so no further heat will be picked up through the heat exchange process. When the Summer Bypass is “off” the air is switched back to run through the heat exchanger again. The summer bypass is not recommended if your home is “air conditioned” and it is being used to cool the inside air. In this case the heat exchanger will act in reverse by cooling the warmer fresh incoming air before it is introduced.
