ABSTRACT:
A method for controlling a motion of a gas valve in a gas feed line coupling a supply device to a burner is provided. The method includes receiving a signal representative of a user-selected desired level of heat output of the burner, translating the received signal to a first current signal, measuring a second current signal in a conducting medium that is operatively coupled with the valve, deriving a third current signal from the first and second current signals, and providing the third current signal to the conducting medium to control the motion of the valve.
