The lower the water temperature, the greater the resistance value. Working range: 0-120 degrees. Alarm temperature: 98 + -2 degrees When the water temperature reaches the alarm temperature and the alarm switch is closed, the alarm light will turn on. When the water temperature decreases and the alarm switch is turned off, the alarm light will be turned off. When the alarm temperature is reached, the response time is approximately 1 second. The water temperature sensor has 2 wires, one is connected to the water temperature meter, and the water temperature parameter is displayed. One connection alarm switch
