These units feature dual set point functionality and multiple fan speed settings. The integrated condensate lift mechanism (27-9/16" lift) allows for long piping and application versatility. These compact indoor units are an excellent choice for office buildings, schools, hotels, assisted-living facilities, and other applications where ceiling space is limited.
