ELIMINATES COLD DRAFTS WindFree™* Cooling technology maintains the desired temperature and eliminates cold drafts by delivering air through micro holes on the unit's fascia panel when the louvers are closed, producing a dispersed and gentle flow of air defined as "still air." The WindFree™* fascia panel includes a humidity sensor to prevent condensation by restricting WindFree™* operation in high humidity conditions. WindFree™* operation is available in cooling mode only. MAXIMIZE ENERGY SAVINGS A Motion Detection Sensor (MDS) will automatically turn off or change the set temperature based on room occupancy, and learn occupancy patterns to reduce run time between occupied and unoccupied times. Use of MDS is optional (sensor sold separately). INDIVIDUAL BLADE CONTROL With independent louver control, the four louver blades can be individually set at the same or different angles within a 32-65° range. COMPACT SIZE The WindFree™* Mini 4-Way Cassette fascia panel is designed to fit in a standard 2x2 ft. ceiling grid without interfering with adjacent ceiling tiles, lights, or sprinkler systems. ADVANCED COMMISSIONING AND SERVICE The WindFree™* Mini 4-Way Cassette is equipped with a removable EEPROM chip on the main circuit board to store unit option settings, serial number, unit tag, and other field programmed data. This allows for ease of startup, commissioning, product registration, and future service work when using Samsung service software (S-Net Pro2).
