What does ERR01 mean on my SMC Networks HEC002-A5 Controller?

If your SMC Networks Controller displays ERR01, it is caused by high-level noise on the power line, ground line, or temperature sensor line. Move the product to an environment with little noise, and turn on the power supply. If there is no alarm, it was caused by noise. Please consult with us.
