Remote controller nonvolatile memory error

What does E1 mean?

Data cannot be read normally from the nonvolatile memory of the remote controller control board. This indicates a critical internal fault within the remote controller's memory, which is essential for storing settings and operational data. The remote controller will be unable to retain settings and function correctly, making system control unreliable.
