The IQ Heat 135 is an encrypted sensor that detects high or quickly rising temperatures. The IQ Heat 135 will notify you if the temperature exceeds 135°F (57°C) or if there is a a rate of rise of 12°F to 15°F (6.7 to 8.3°C) per minute. With the IQ Heat 135 you'll know if there is a problem before it becomes a disaster.
