Keystone's reliable through-the-wall air conditioning units offer consistent cooling and enhanced comfort, even during the hottest days. With easy through-the-wall installation, this 10,000 BTU air conditioner provides efficient cooling for rooms up to 450 square feet, while the dehumidification feature removes up to 2.3 pints of moisture per hour, improving air quality. Designed for smaller living spaces such as apartments, dorm rooms, and sheds, this unit also offers supplemental heating capacity of 10,600 BTU. The supplemental heating mode is intended for use when outdoor temperatures range from 23 to 76 degrees Fahrenheit and is not meant to serve as a primary heat source. Equipped with a unique remote control, this unit features a built-in thermostat that accurately senses the room temperature, displaying it on the remote's LCD screen, and communicates with the AC unit every 3 minutes to ensure precise cooling. Energy-saving options such as the energy saver mode, sleep mode, and programmable 24-hour timer help reduce electricity costs. The Check Filter alert reminds you to clean the easily removable mesh filter, ensuring optimum performance. Please note that this unit requires a special 230-volt/20-amp electrical outlet and is incompatible with a standard 115V household electrical outlet.
