The two-stage design allows the unit to run at 67% capacity most the time to maintain a consistent temperature and humidity level. When there's a demand for greater heating and cooling (such as during temperature extremes), the unit automatically and instantly changes to 100% capacity. This part load/full load capacity significantly lowers annual operating costs while increasing comfort.
In addition to the full load/part load operation, an ECM variable speed blower motor adds to comfort and efficiency with a multitude of operational modes. The blower motor automatically adapts to all applications.
The twostage heat pump system uses environmentally friendly R-410A
The HEV Series is available in 2 to 5 ton capacities
