The current disclosure relates to steam generation and supply apparati and associated control systems. A provider stores a message in the SIM based on a payment, which determines the level and period of services to be provided. In particular the load elements can be selected from inductive resistors or silicon resistors or be constituted by resistors of a size selected to optimize the noise inversely proportional to frequency. In response, if the AP is the root AP, the root AP operates as a proxy controller through which the traffic may be routed. Electrical connection lines between the components andor the contact areas on the interconnect device and an electrical contact area on the end section of the foil conductor strip create the electrical connection between the control electronics on the interconnect device and the surrounding area outside of the control device.
