If you wish to change the room temperature, you can operate it at the panel that you will find in your room. The magnetic key of the room must be in the electricity slot for it to work. The air conditioning will switch off automatically when you open the terrace door in order to save energy.
Upon your arrival, it is normal that the room could be warmer than normal. Connect the air conditioning as above explained and let it work for a reasonable time. You will soon notice how the room begins too cool.
