Abstract

In an electric system that controls electrical or state variable devices through inputs received from device operators such as switches, buttons and the like, where some of the button control or set sequences for the electrical devices and others predefined “presets”, an automatic sequence tracking process monitors the system and adjusts the position of the sequence steps for buttons that are associated therewith, to ensure that they always track the current condition of the electrical devices. Thereby, actuation of sequence generating buttons will always choose the next step in a sequence for the corresponding electrical device.
