<p>In the case of a charge controller for electrical heat-storage heaters, a switching device is provided which consists of a first switch and of a further switch. The two switches are independent of one another and each have a diaphragm box as the drive. A sensor device for detecting the storage core temperature consists of two capillary tube sensors, one of which is connected to the diaphragm box of the first switch and the other to the diaphragm box of the further switch. Furthermore, a sensor element is provided for detecting the external temperature, which is likewise constructed as a capillary tube sensor, is adjustable by an external automatic controller and whose capillary tube is connected only to the diaphragm box of the further switch. A manually operable adjusting device is arranged on the diaphragm box of the first switch. By splitting the manual adjustment and the automatic control between two mutually independent switches, the adjusting device is prevented from influencing the automatic controller, and vice versa.</p> |
