I-Feel technology uses a temperature sensor built directly into the remote control rather than relying on the sensor inside the indoor unit on the wall. When activated, the system adjusts its performance based on the temperature surrounding the remote, which is usually where you are sitting. This eliminates the common problem of the ceiling being the "right" temperature while you are still too warm on the couch. You can find this smart feature in most of our Cooper&Hunter and Bravo units. It is the ultimate tool for personalized comfort in any one zone wall mount installation. It also helps the system maintain better humidity control by sensing the air at your level.
