When it senses a room is unoccupied, the Wall Mounted 9RLS2 adjusts temperatures accordingly. The device incorporates Fujitsu’s ESP (Energy Saving Program), which uses a motion sensor to determine when a person has left a room. Twenty minutes later, the unit increases room temperature by 4 F when in cooling mode, or drops the temperature by 8 F in heating mode. Available in 9,000, 12,000, and 15,000 BTU configurations, the 9RLS2 has a seasonal energy efficiency rating (SEER) of 27.2. fujitsugeneral.com
