The good plan B

The previous owners have abandoned a portable air conditioner exotic brand (Enviracaire Climair 8RC HCL-725RE) without a remote control, I have sought to replace it. Only a German website offers a dissuasive price which appears to be the original part.
I fell back on it, relying on the automatic search function and, miraculously, in a few moments the two devices have communicated!
For occasional use, this remote seems a good plan B, at an acceptable price.
