I have noticed that if you have issues with your Control:10/15 it may be wise to verify that it is not a faulty power supply. Although the power supply could give indications that it is fine with initially powering up the C10 and having its light on power supply illuminated. It still could be faulty if you experience any other issues such as freezing or shutting down. This was verified with one of my units. Swapping out the power supply cleared up any issues.
