The ZS U2 is a modern light time pulse switch that combines a high level of comfort, flexibility and functionality with easy handling and operation. By pressing the light button briefly or for a longer period of time, you can choose between two independently adjustable time ranges. This enables individually configurable short-term / long-term switching in a range of 0.25 to 150 minutes. Pressing the light button again immediately switches off the consumers. Two operating modes allow you to block the long-term switching. Due to its small installation dimensions, it can also be installed in switch boxes, e.g. behind a conventional button, and is therefore also suitable for renovating old buildings.
