A 60,000 BTU outdoor condenser powers cassette heads that slide neatly between ceiling joists while providing whisper-quiet heating and cooling down to -13 F. One-Way cassettes use TU1 copper heat-exchangers, an integrated condensate pump, built-in Wi-Fi smart kits, and eco-friendly R454B refrigerant for efficiency up to 22 SEER2. On the 6K-12K model a simple ENC1 dip-switch lets you select 6K, 9K, or 12K capacity on site for true application flexibility.
