Compact rainwater utilisation system compliant with DIN 1989-100 and DIN EN 16941-1 with flexible manifold on the discharge side to save drinking water. Made up of two non-self-priming, horizontal, high-pressure multistage centrifugal pumps from the Wilo-Medana CH1-LSP series (pressure-boosting pumps) and feeding pump (ordered separately) in the rainwater storage tank (see Wilo-Padus UNI or Wilo-Sub TWI, for example). Mounted on baseplate with height-adjustable pedestal, ready for connection, including switchgear for comfortable system control.

  • Fully automated rainwater utilisation or fresh water replenishment in case of drought in large commercial or industrial buildings.

Special features/Product advantages

  • Compact, factory pre-assembled design enables easy installation
  • Simple and intuitive operation via EC switchgear combined with Green Button Technology
  • Automatic replenishment with drinking water permits reliable, continuous operation even in drought conditions
  • Flow-optimised design and deployment of IE2/IE3 motors enable energy-saving operation
  • Self-protection routines, control in the low voltage range, the use of corrosion-resistant components and the optional integration into a building management system facilitate high operational reliability
  • Maintenance notifications in the fault display via error codes
  • The integration into building automation via standard Modbus and optional extended communication via Wilo-Gateway enables remote monitoring
  • Quiet operation for very comfortable usage equipment/function

Equipment/function

  • Two high-pressure multistage centrifugal pumps from the Wilo-Medana CH1-LSP series with IE2/IE3 motor technology (IE2: up to 0.75 kW, IE3: from 0.75 kW)
  • Baseplate in a vibration-insulated design with height-adjustable pedestal
  • Two-way valve allows automatic switchover to drinking water replenishment in case of a lack of rainwater in the storage tank
  • Replenishment reservoir (volume: 400 litres) functions as a hybrid tank with overflow conforming to EN 1717 (free drain type AA) to pump rainwater and demand-oriented replenishment of fresh water when rainwater storage tank is empty
  • Throughflow diaphragm expansion tank (volume: 8 litres) conforming to DIN 4807 for energy savings if there are very small leaks in the building
  • Filling level sensor with 1.5 m cable (measurement range 0 to 5 m) allows the amount of water in the hybrid tank to be detected
  • All parts that come into contact with the fluid are corrosion-proof

on the discharge side:

  • Ball valve at each pump
  • Discharge manifold that can be connected on both sides
  • Throughflow diaphragm expansion tank (8 litres)
  • Pressure sensor 4 – 20 mA
  • Pressure gauge
  • Threaded cap or blind flange depending on the nominal diameter of the manifold (must be ordered separately)

on the suction side:

  • Pressure sensor 4 – 20 mA
  • Pressure gauge
  • Threaded cap or blind flange depending on the nominal diameter of the manifold (must be ordered separately)

Automatic pump control via fully electronic EC-Rain switchgear (Easy Control) in a metallic housing, protection class IP54. Ready for connection as electronics and hydraulics are already hooked up. Mounted on an anti-corrosive painted tubular steel structure.

A working area of 60 cm around the system is recommended in order to facilitate the maintenance process.

Operation/display

  • Two separate LED displays (1 EC(e) booster circuit board to control the feeding pump, 1 EC-rain circuit board to control the high-pressure multistage centrifugal pump of the Wilo-Medana CH1-L series) show operating data, controller parameters, operating statuses of the pumps, error messages and history memory
  • Menu navigation with seven-segment display and visualisation
  • Factory-preset parameters for easy commissioning/start
  • Setting of operating parameters and acknowledgement of fault messages using rotary knob
  • Lockable main switch
  • Elapsed time indicator for each pump and for the entire system
  • Dry-running and overflow meter
  • Fault memory for the last 10 faults

Control

  • Two non-self-priming centrifugal pumps from the Wilo-Medana CH1-LSP series (p-c control mode)
  • One feeding pump (ordered separately), for example Wilo-Padus UNI or Wilo-Sub TWI
  • Adjustable switch-on and -off pressure for base- and peak-load pump in relation to the defined duty point
  • Adjustable fill level in the hybrid tank to activate the feeding pump
  • Automatic, load-sensitive cut-in of the peak-load pump depending on the start-up pressure of the base-load pump
  • Several user levels with different rights and menu scope and presentation of comprehensive information on the main screen
  • Easy Actions menu for quick configuration of basic parameters
  • Freely selectable operating mode of pump (manual, off, automatic) and two-way valves (opened, closed)
  • Steady system control by means of pump cycling and integrated test run on idle pumps
  • Operating modes of the systems (manual or automatic)
  • Automatic, configurable pump cycling
    • Standard setting: Impulse - The base-load pump is cycled at each new demand, regardless of operating hours
    • Alternatively: pump cycling of base-load pump after set number of operating hours (EC(e) booster interval: 6 hours; EC-Rain interval: 1 to 6 hours)
  • • Automatic, configurable pump test run (pump kick)
    • Can be activated/deactivated
    • Time between two pump test runs is freely programmable
    • Disabling times can be programmed as desired
    • Speed can be adjusted as desired

Monitoring

  • System/level control in low-voltage range (24VDC)
  • Level monitoring of the rainwater storage tank with overflow detection and metering
  • Hybrid tank: High water alarm and overflow detection
  • Over/underpressure detection
  • Dry-running protection of pump
  • Calcination protection of the two-way valves
  • Automatic periodic water exchange in the hybrid tank (intervals selectable)
  • Collective run and fault signals via potential-free contacts
  • Optional inputs/outputs (see interfaces)

Interfaces

  • Potential-free contacts for SBM/SSM collective run and collective fault signals
  • Logic reversal can be applied to SBM and SSM
