Abstract

Power outputs in a heating control and/or regulation device are each electrically connectable to a heating element, especially a radiant heater. A power input is able to be connected electrically to a power supply for the heating elements. A power distribution device is connected electrically on its input side to the power input and is connected electrically on its output side via a branch to each of the power outputs to supply the power outputs with electric power from the power supply. A switching element is disposed in each of the branches or between each of the power outputs and the heating elements. A control and/or regulation unit is configured such that it controls and/or regulates the switching state of the switching elements as a function of set values. An interface receiving set values has at least one additional connection to a temperature measurement device that measures actual values of temperature. The control and/or regulation unit is configured such that it acquires the actual values of the temperature from the temperature measurement device and additionally controls and/or regulates the switching state of the switching elements as a function of these actual values of the temperature.
