  • electric storage heaters also have a charge regulator which receives the release signal for the charge releases within low load times either directly or indirectly via a central control device which is jointly assigned to a storage device group. If necessary, the charge controller also receives a control signal via the central control device, which sets the setpoint of the storage core heat content depending on weather and time values as well as preset parameters. The actual value of Speicherkern- heat content 'is detected by a high temperature sensor, which is connected to the Aufladeregier.
