Abstract: 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.

Abstract: A self-adjusting balance valve controller controls water flow through a hydronic emitter in a heating and/or cooling temperature control system. The valve controller obtains a measured temperature differential between an inlet and an outlet of the hydronic emitter and determines a displacement of a coupling pin from the measured temperature differential. The valve controller then instructs a driving mechanism to move, through a coupling mechanism, the coupling pin to adjust a valve that results in a desired water flow through the hydronic emitter. The valve controller may maintain a stable temperature differential at a desired differential value, which may be obtained through a user interface or from a memory device. Moreover, the desired differential value may vary with different times of operation or temperature control situations.
