Single Phase Dual Pump Rain/Mains Pump Controller with BMS

The unique MATelec Rain/Mains Dual Pump Controller is designed to provide a continuous supply of water for a variety of uses, whilst prioritising and maximising the use of rain water. The system comprises of a controller, a pulse latching solenoid valve and float switches. The controller not only monitors the level of stored rain water and switches the valve accordingly, but controls two single or three phase pumps in a pressure pumping system.

  • Smart chirp mode alarms - Alarms automatically silence after 5 minutes if not muted, then chirp every 5 minutes
  • Manual control - Manual pump mode with optional 5-minute timeout to revert back to auto mode
  • Duty sharing and alternation - Duty pump alternates on pump start and after 30 minutes of continuous running in alternation mode, or after 6 hours of accumulated running in circulation mode
  • Pump staging and destaging - Second pump is staged into operation on high level and destaged when no longer required
  • Staggered pump start - Prevents excessive current draw and reduces water surge
  • Controlled by - Lead pump, lag pump and low pressure switches
  • Rain water use - If rain water becomes available, the controller pulse closes the mains water valve and the pressure switch will control the pump
  • IP56 rated, powder coated mild steel enclosure with inner door and removable gland plate
  • Pad-lockable mains power isolator switch
  • Circuit breaker protected low voltage control and input circuitry
  • Individual pump isolation
  • Contactor and thermal overload protection of pumps
  • Din rail mounted terminal connections
Control & interface
  • Dual pump keypad interface:
    • Indicator lights for power on, high & low-level alarm, pump run, pump fault/overload and prime loss
    • Push buttons for alarm mute/reset, pump auto/off/manual control
  • Rain/mains keypad interface:
    • Indicator lights for mains and tank water use, system fault
    • System test/reset button for checking pump and valve function, resetting faults
  • PCB control module with dipswitches for adjusting configuration
  • Rain/mains PCB control module for rain/mains changeover functionality
  • Visual (strobe) and mutable audible (buzzer) alarms

Fault Protection

  • Pump overload protection - Shuts down pump/s on overload, with automatic duty alternation
  • Low pressure alarm - Shuts down pump/s if unable to build pressure within 60 seconds, after the low-pressure input closes
  • Mains water use - In the event of rain water depletion, pump fault or power failure, the controller shuts off the pump and pulses the valve open for mains water use.

Modification Options

  • 316 stainless steel enclosure
  • Generator input socket and automatic changeover
  • Me-Link 4G SMS alarm sender
  • Conductivity probes inputs and rain/mains level indication keypad

  • BMS volt free outputs for power on, mains water, pump run and pump fault (BMS version only)
Included with panel
  • 25mm female/female 12Vdc pulse latching solenoid valve.
