Applications

Rainwater utilisation in single- family houses for reducing potable water consumption in connection with cisterns or tanks.

Toilet flushing

Sprinkling/irrigation

Supplying machinery

Secondary cleaning purposes and other applications in the non-potable water sector

Function/construction

Ready-to-plug single-pump water supply system as compact module for single-family houses. For completely automatic supplying of rainwater from an underground tank or from a cistern. The 11-litre replenishment vessel offers optimised replenishment of potable water into the consumer network when cisterns are not full. Automatic Switchover to potable water replenishment, pump operating time-dependent water replacement in the replenishment vessel, anti-lime deposit protection through automatic actuation of the solenoid valve, built-in automatic switch-off during dry running. Variable switch-off pressure. Commissioning with base parameters set ex-works (plug & play) by means of the RainControl Economy RCE electronic control device. Permanent operating data recording, energy-saving mode function, operating state protocol. Operation and parameterisation by means of user-friendly, menu-driven function keys. The system fulfils the criteria outlined in DIN 1989 and in EN 1717.

Planning Guide

The suction line is to be laid in an uninterrupted rise from the cistern to the AF system. A clearance of at least 200 mm is to be provided for above the system for correction purposes. A clearance of at least 100 mm is to be provided for to the left of the system in order to ensure ventilation of the pump motor. For additional planning instructions and/or details concerning the planning of rainwater utilisation systems, see Wilo-Brain “Rainwater Technology Handbook”.

Product advantages

Compact, ready-to-plug rainwater utilisation system

Low-noise, thanks to multistage rotodynamic pump and complete encapsulation of the system

Automatic support function for evacuation of air from the suction line

In compliance with DIN 1989 and EN 1717

Upholding of previous performance parameters; this ensures that interchangeability with previous systems will be maintained

High economic efficiency, thanks to fresh water replenishment according to requirements
