Product Details

The Keystone 12,000 BTU 230-Volt through-the-wall air conditioner with 10,600 BTU Supplemental Heat Capability is perfect for rooms up to 550 sq. ft. In addition to cooling, this versatile unit also offers supplemental heat capability, providing you with an additional heat source to your main heat source when outdoor temperatures are above 45°F. It has electronic controls with LED display and a temperature sensing LCD remote control allowing you to conveniently see, set and maintain the room temperature from across the room. Money saving features include energy saver mode, sleep mode and a programmable 24-hour timer. This unit is designed for through-the-wall installation and is not designed for standard window installation (WALL SLEEVE SOLD SEPARATELY). This unit also requires a special 230-Volt/20-Amp electrical outlet and will not operate with a standard 115-Volt household electrical outlet.
  • SUPERIOR COOLING AND HEATING: With a 9.5 energy efficiency ratio (EER), this 12,000 BTU through the wall air conditioner can effectively cool rooms up to 550 sq. ft and dehumidify up to 2.5 pints per hour. (Product is not suitable for window installation)
  • 230-VOLT/20-AMP ELECTRICAL OUTLET REQUIRED: This air conditioner has a 6.5ft power cord with a NEMA 6-20P grounding plug that will not fit a standard 115V electrical outlet.
  • TEMPERATURE SENSING "FOLLOW ME" REMOTE CONTROL: With a thermostat built into the remote control, say good-bye to uneven room temperatures. The remote makes it easier to control the unit from anywhere in the room and its integrated thermostat signals the AC to cool the space based on where you are.
  • FRONT-ACCESS FILTER: Let's face it. Filters collect dust. With our front-access design, cleaning that dusty filter is a piece of cake. Simply pull it out, vacuum or rinse and dry, and slide back into place. No hassle and no disassembly required.
