[+} Increase Size
In operation, the pressure sensor provides dry running protection and pressure controlled disconnection for convenient handling - the pressure is shown clearly on the LCD display. Should there be a shortage of rainwater, mains water is supplied on demand until sufficient rainwater is again available. At the same time, a zone valve makes the changeover controlled via a float switch in the rainwater tank. The mains water is fed in accordance with EN 1717 via a proportional float valve.
As stagnation protection, the water in the mains supply tank is changed after a standing time of 30 days. The change to mains water operation can also be made manually. All connections are designed as screw connections, except for electrical connections which are plug-in. Covers, pumps and mains water tanks are provided with vibration protection components. The floor-mounted system controller is easy and quick to install.
