Once the solar water heater at home fell ill, and the water supply, water level, and temperature were abnormal.
I checked the information on the Internet and said that it may be the problem of the sensor, but also that there are other possibilities.
I'm not sure what the problem is, so I have to find someone to repair it.
The person in the background also replaced a sensor and collected a hundred yuan.
Later, I searched on a certain treasure, and the sensor was about five to twenty or thirty.
Later, we need to pay attention to the selection of sensors:
1. Is the sensor mounted on the upper side of the solar water tank or on the top?
2. Is it 2-core or 4-core,
In fact, just ask the store for the model of the water heater, and the store will tell you which one to buy.
