The resistance of an RC element is determined. If the heating device is only to be continuously crest-controlled in the upper half of its power range, a diode can be connected in anti-parallel to the thyristor so that the negative half-wave in relation to the thyristor is fed to the consumer in an uncontrolled manner. It is also possible to have a heating stage with double power to be provided if, according to the invention, in the case of half-wave control, the thyristor is assigned a bridging contact, the actuating element of which is advantageously coupled to that of the setting resistor of the RC element. : A roll path control results when ar: set the thyristor a ', 7,' echsc # lstromtor (triac) is used. ir.
