As the season approaches for cooling in North America, we want to share some information on Summer Bypass, or Night Cooling. Most of our units provide for automatic Summer Bypass and utilize programming that senses when the inside temperature is warmer than desired, and the outside temperature is cooler than the inside temperature. A damper is automatically opened that routes the outgoing warm air around the heat exchanger, and allows the cool outside air to come directly into the house, through the filters, and to the living spaces. This allows for cool evening/night air to cool the house down without opening windows. Although this has limits to the amount of cooling achieved, it is a very efficient way to temper the house during the summer season.
