I have a Mitsubishi Mr Slim, model MSY-A24NA, installed in a computer room. I'm having trouble getting it to regulate the temperature correctly. What's the best way to set it up so it maintains a constant temp. It's working but the temp is at 70 degrees and I don't need it that cold in there. If I raise the temp on the wireless remote, it still stays at 70. I guess I need to know how to set it up including vane, fan, mode, etc.
