It is controlled by the hotel and you get what heat they want to give you and when they want to give it to you. Carrying a small electric heater is not a bad idea at certain layover hotels. The cultural difference is huge in this respect as Chinese just put on another layer of clothes if it is cold whereas the Western mentality is to relax in our underwear in out hotel layovers and set the thermostat where you want it.
