Optimize energy efficiency: Adjust the operation mode and power according to the ambient temperature, humidity, etc., so that the air conditioner can run efficiently and reduce energy consumption. Pressure protection and control: the high-pressure sensor monitors the refrigerant pressure at the condenser outlet, which will not be too high, and the low-pressure sensor monitors the evaporator outlet pressure, which will not be too low, ensuring the safe operation of the equipment. Stable and reliable: After severe environmental testing, it can work stably under harsh conditions such as high temperature and high humidity to ensure the long-term stable operation of the air conditioner. Rapid Response: It can sense temperature changes in a very short time, quickly provide feedback to the air conditioner, timely adjust the operating status, and reduce temperature fluctuations. 1Pcs Temperature Sensor ，Compatible ForGree ，F3 F4 F5 External 6-wire Inverter Air Conditioner, Weight: 0.110231131 pounds, Manufacturer: GENTERUN
