A heating system includes a single thermostat that controls multiple thermostatic radiator valve (TRV) controllers that control heat transfer to radiators in a room. Each TRV controller has the capability to automatically detect the open/closing point and maximum heating point and to register corresponding pin positions of the valve. Each TRV controller is subsequently instructed by the thermostat to adjust the valve in relation to a determined percentage of the registered pin positions, thus accounting for the varying characteristics among the valves in the system. The TRV controller detects the maximum heating point by checking the rate of temperature rising and the open/closing point by sensing the temperature turning point through a temperature sensor situated appropriately in relation to the associated radiator.
