Introducing the new TX9000RF and the convenience of radio frequency technology to temperature control. Unlike infrared remotes that require a direct path to operate an electrical device, the TX9000RF utilizes radio frequency, allowing the user to make adjustments to the temperature from virtually anywhere in the home. The TX9000RF also uses the latest in digital technology for highly accurate temperature control, a large lighted display for easy readability and the Lux Speed Dial®, a patented device that makes reprogramming simple. The TX9000RF is 7-day programmable and just as important, it meets the rigorous Energy Star® regulations for energy savings. Summary of Features: System or Battery Powered (6 "AA" Batteries Included) WARNING: When Replacing Batteries Use Energizer ® or DURACELL ® Alkaline Batteries Only, 7 Day Programmable - Each Day Can Be Different
