A solar sensor is placed in the solar water tank to detect the water temperature and water level, and transmits signals such as water temperature and water level to the meter, which then displays the temperature, water level, and controls the water replenishment device.
Common sensors on the market include the following types: Huangming solar sensor (including Yijianeng):
Other brands of universal solar sensors:
Note: Since Huangming meters and other sensors are not interchangeable, other universal sensors cannot be used with Huangming solar; if Huangming solar replaces both the meter and sensor, other sensors can also be used. So when the sensor is broken, and you feel that finding someone to replace it will cost a lot, how can you replace it yourself? Step 1: Confirm the brand and model, and purchase accurately. First: Confirm the brand of the meter, whether it is Huangming or another brand, and then purchase the sensor yourself. If it is a Huangming meter, only Huangming sensors can be replaced. (Replacing the Huangming bottom-mounted sensor is slightly more complicated, for those with poor manual skills)
Second: If it is another brand of meter, follow these steps: 1. Universal sensors are divided into 2-wire and 4-wire; you can determine whether it is 2-wire or 4-wire by observing the meter panel, meter terminal, etc. After confirming which type of wire the meter uses, purchase the corresponding sensor, otherwise it cannot be used if purchased incorrectly.
A point to note here: If the meter displays that it is compatible with both 2-wire and 4-wire, do not purchase sensors (with 0.5-meter wire) indiscriminately. You need to check whether the connection wire from the meter to the sensor is 2-wire or 4-wire; buy the same number of wires as the connection wire, or purchase a sensor with a 20-meter wire.

2. Determine the installation position of the sensor, whether it is side-mounted, top-mounted, or bottom-mounted.
Step 2: After purchasing the sensor, how to replace it: To replace the sensor, you need to go to the roof, Safety first! Safety first! Safety first!
After pulling out the old sensor, insert the new sensor, when connecting the sensor wires, be sure to match the colors of the wires!!!
