Abstract

1. Supplementary device for several electrical direct heating devices (1, 2), one of which as main heating device (1) has a thermostat (1a), the supplementary device (3) containing a current sensor (3a, 3b) through which the current of the heating resistor (1b) of the main heating device (1) flows and the current sensor (3a, 3b) operating a semiconductor switch (3c) for switching on and switching off additional direct heating devices (2), characterized in that the current sensor is a current transformer (3a, 3b), the primary winding (3a) of which is series-connected to the thermostatically regulated main heating device (1) and the secondary winding (3b) of which is arranged in the control circuit of the semiconductor switch (3c).
