Abstract

In a method for automatically triggering flushing of a urinal with water an electrically actuatable shut-off valve is arranged in the water inlet line for shutting off water flow. A temperature sensor is positioned at a siphon of the urinal. Signals generated by the temperature sensor are sent to an electronic control and computing device. A temperature gradient is determined with the electronic control and computing device based on the signals generated by the temperature sensor. The shut-off valve is opened for flushing the urinal when the temperature gradient exceeds a preset limit.
