The controls for the HVAC are surprisingly through the TV's hotel web site. An old thermostat is still on the wall and powered to show temperature, but is otherwise non-functional and misleading. The web site for room control itself is rather confusing, and I had to get a staff member to show how to work it. For example, there is a button saying "ON", but counter-intuitively, you need to leave it alone of you really want the system to be on. If you click the "ON" button, it turns the system off. Eventually, a little experience solved all the problems, but it was an annoyance to have to learn the hard way. This was only a minor concern--most of the hotel was very nice and a very good value.
