AUM 18P is a stainless-steel tap controlled with a piezo button, intended for installation on the basin with the D33 hole.
When you touch the button, water starts flowing for the preset time. This cycle can be repeated arbitrarily. After two cycles, there may (or may not) be a pause during which the water is not flowing.. If the button is touched during this period, nothing happens and water does not flow. The delay period can be set to 0 – 42.5 minutes. If the delay period is set to 0, water can be turned on any time by touching the button.
