Sorry I must have delivered the info a bit confusing. Its not working at all no matter where it is plugged in, by itself or other. And it has been working plugged into the outlet its currently in for over a year.

In all honesty I don't know what setting it is on. I have the temp set at 88 and the dif at 1. Otherwise, I don't know what settings there are.

I will look for the manual online, and I will email RBI if I can't figure it out
