ABSTRACT:
The control device has a power regulator for the timed power to the heating system of the electrical apparatus. The heating system is provided with a temperature sensor which, up to a given desired temperature, bridges the power regulator with the aid of a temperature switch, so that full power is supplied to the electrical apparatus heating system. On exceeding the desired temperature, power is supplied to the electrical apparatus via the power regulator.
The temperature sensor is additionally heatable by an auxiliary heating system to obtain a variable changeover temperature of the temperature switch (22).
The auxiliary heating system is preferably always switched on when the heating system of the power regulator is switched off.
