Description
Electronic water stop - to protect against water damage (no interruption of water supply in case of power failure). Ball valve with external thread M 1" for combined size ¾" +1" and M 1 ½" for combined size 1 ¼" and 1 ½". (*max. distance to BWT Perla 30 m).
1. Intended use
For opening and closing a water-carrying line in buildings manually or through remote control after an event is reported by the floor sensor(s). AQA stop Wireless comprises a shut-off valve and control unit with a power supply and EnOcean® wireless module. The shut-off valve comprises a ball valve that is certified for use with drinking water and includes an electric motor that is integrated into the water-carrying line. Four designs with suitable connections are available for a variety of line diameters: G ¾", G 1", G 1¼" and G 1½" connection thread. The shut-off valve for the water-carrying line can be opened and closed in three different ways: – By mechanically opening and closing the shut-off valve using the control lever – By electrically opening and closing the shut-off valve using buttons on the control unit – By closing the shut-off valves via the floor sensors The control unit is in constant contact with the programmed floor sensors. An event message is triggered if a leakage is detected by the floor sensors (for example, due to leaking household devices or a burst pipe in a water line). The water line is then closed by the AQA stop Wireless to prevent any more water from escaping.
2. Function
If the floor sensor comes into contact with water, the AQA stop Wireless cuts off the water supply after about 6 minutes. This minimizes water damage that can occur due to pipe bursts and pipe cracks.
3. List of supplied parts
AQA stop Wireless comprising:
- Brass shut-off valve with drinking water certification.
- Control unit with power supply and EnOcean wireless module and 0.9 m mains cable.
- Floor sensor with EnOcean technology.
4. Installation conditions
The range of the floor sensor depends on the materials installed in the building. The unit requires a constant power supply. Observe all applicable installation regulations, general guidelines and technical specifications. An earthed power socket is required for the electrical connection.
5. Functional and warranty conditions
This BWT product requires regular functional monitoring, maintenance and replacement of important parts after certain intervals. See the installation and operating instructions for the maintenance intervals.
