TRV controls the room temperature by sensing the room air temperature and automatically opening or closing the flow in order to maintain preset temperatures. A manual valve controls the temperature of the radiator regardless of the room air temperature. Radiators of 1800 Watts or more are recommended to use TRVs as they save people having to continually adjust the radiator temperature.
