Typically, the model name is displayed once on the FND display during product startup and then disappears. However, if the model name is continuously displayed or alternates with the temperature, it is highly likely due to electrical noise. Please try the following method to resolve the issue.
First Method: Separate Wiring
- Bundle the sensor line, communication line, and load machine connection line together, and separate the power supply line to operate the device. Installing the power supply line, sensor line, load connection line, and communication line in the same conduit or duct can increase the likelihood of noise. This may cause unstable power supply, leading to errors where the model name is continuously displayed or alternates with the temperature.
Second Method: Use a Noise Filter
- Purchase a noise filter to prevent electrical noise and connect it to the power line for operation. This can help reduce noise and resolve the error.

The product memory may have been damaged due to noise.
