The Aqua-PIR can prevent wastage of water and as a result can help prevent excessive consumption and damage caused by water leaks. With the valves in a normally closed position, the water supply to a WC or washroom is switched off. When the PIR detects that the room is occupied, the valve opens and water is allowed to flow normally. On leaving the room, a pre-set length of time will elapse and the valve closes again.
The Aqua-PIR can also be connected into the lighting system to switch the lights on and off during room occupancy.
