The 7 Series represents our top-of-the line products and the 700A11 is quite possibly the most advanced heating and cooling system on the planet. It signifies groundbreaking innovations on multiple fronts–most notably as the first variable capacity geothermal system available to homeowners and the only product to surpass both 43.5 EER and 5.1 COP. It’s vastly more efficient than any ordinary heating and cooling system and 30% more efficient than any other two-stage geothermal heat pumps. The 700A11’s variable capacity technology works in concert with a variable speed loop pump and variable speed blower motor to provide a level of comfort you need to experience to believe. The unit also provides the industry’s widest capacity range–from as low as 20% to as high as 130% - to keep homeowners comfortable over the widest scope of conditions. Active dehumidification, advanced hot water generation logic, SuperBoost™ cooling, IntelliZone2 compatibility, and energy monitoring are additional features that make the 7 Series one of a kind.
