You can turn the temperature down to 16 degrees on the controller, but Im not sure it would hold a room at that temp on the hottest days. I woulnd't have thought you'd want to however. If the intent was to mis-apply it as a cellar cooler (I've had that a few times) I'd use something else. If youre based in the UK and have more questions though feel free to contact me directly - *****@*******.com (I'm a sales engineer in the AC team)
