<p>Further sensors (8a, 8b, 10a, 10b) have two operational modes like the first (9), corresponding with two detection regions of differing sizes. A further detection circuit is connected to them. This similarly produces an output as long as a person or object is detected in the more extensive region, the signal controlling a driver circuit. A further logic circuit associated with the further sensors, controls other attributes of the water flowing to the shower, on detection of a person or object in the smaller region.</p> |
