RMQ 3-45-A A-W-A-BVBP

The RMQ rainwater unit is designed for the monitoring and control of rainwater collection and utilisation systems. The unit detects faults in the rainwater collection system and makes the necessary adjustments to ensure that the system is operating.

When insufficient rainwater is available from the collecting tank (e.g. underground tank), the RMQ unit switches to mains water supply, thus providing sufficient water at the points of consumption, e.g. water closet, tap. The connection between the integral mains water tank and the suction pipe from the collecting tank is closed by means of the built-in three-way-valve.

The RMQ unit has been approved for

  • the control of rainwater collection systems,
  • as domestic waterworks for the utilisation of rainwater,
  • for operation in residential and commercial areas as well as for small enterprises.
