Features: 1.The temperature controller sensor is mainly used to measure the floor temperature of the floor heating temperature controller, and it is also suitable for monitoring pipeline water temperature, indoor temperature and outdoor temperature. 2.The resistance of the floor temperature sensor at 25 掳 C is 10k ohm, and the floor heating cable is compatible with all types of radiation heating systems. 3.NTC sensor's rubber thermoplastic protective shell, waterproof and rust, sturdy cable insulation layer can prevent the sensor from being damaged. 4.It is easy to connect to the hemoosener, and the sensor probe can stick to the electrical film to accurately measure the floor temperature and communicate with the thermostat. 5.The cable is about 3 meters long, suitable for most standard installation. The annex of the electrical controller is not polar, and only the two wires are arbitrarily connected to the sensor socket on the thermostat.
