ELECTRICAL HEATING APPARATUS, IN PARTICULAR UNDERFLOOR HEATING
First Claim
1. An electrical heating apparatus comprising:
- a heating conductor device containing;
a first heating circuit with a first power stage, andat least one second heating circuit with a second power stage,a heating temperature setting unit that sets a set-point temperature;
a temperature sensor that measures an actual temperature;
an activating device that activates the heating conductor device on the basis of the respective values of the set-point and actual temperatures;
a first energy source; and
a single control apparatus with a control module, said single control apparatus being designed as multistage controller, whereinthe single control apparatus is connected between the first energy source and the heating conductor device,the heating temperature setting unit and the temperature sensor output their signals to the control apparatus, andthe control module activates or deactivates first and second power stages individually or in combination on the basis of the difference between the set-point and actual values.

Abstract
An electrical heating apparatus comprises a heating conductor device having at least one heating circuit with at least one power stage, a heating temperature setting unit that sets a set-point temperature, a temperature sensor that measures an actual temperature, an activating device that activates the heating conductor device on the basis of the respective values of the set-point and actual temperatures, a first energy source and a single control apparatus with a control module, which is connected between the first energy source and the heating conductor device. Further, the heating temperature setting unit and the temperature sensor output their signals to the control apparatus. The control module activates or deactivates first, second and/or additional more power stages individually or in combination on the basis of the difference between the set-point and actual values.
