HydroWHIZ Variable Speed Pump (VSD) Controller and Module

MATelec Australia’s HydroWHIZ Controller has been designed with ease of use at the core of the system design. Building on the wealth of the pump control features in the Advanced controller, the HydroWHIZ brings these features into a new age with a colour touch screen interface and a streamlined setup process. In a world where information is power the
HydroWHIZ has extensive time and date stamped alarms, logged data, trend graphs and diagnostic pages to provide the user with all the information required for optimisation and preventative maintenance.

Featuring the flexibility of level, pressure and temperature system modes with a wide range of functions and protections, the HydroWHIZ VSD controller is ideal for a wide range of applications including water transfer, stormwater and sewage pump out, constant pressure, hot water circulation and chiller supply, to name a few. The External VSD version optimises the onboard smarts of a complete system using external variable speed drives.

Function Features
  • Multi pump control - Control of up to 6 pumps in any number of duty, duty assist and standby pump configurations
  • Pump limiting - For limiting max flow or power requirements
  • Duty sharing and alternation - Adjustable duty change period and bumpless transfer
  • Pump staging and destaging - Additional pumps are staged into operation to maintain setpoint and destaged when no longer required
  • Staggered pump start and stop - Prevents excessive current draw and reduce water surge or hammer
  • Manual control - Manual modes for system and pumps with 10 minute timeout to revert back to auto mode
  • System types - Level, pressure or temperature control modes
  • Control directions - For emptying or filling a tank, boosting or dropping pressure and heating or cooling temperature
  • Speed control of pumps - Proportional speed control for level and temperature control, PID control for pressure with adjustable proportional and integral values to change VSD responsiveness
  • Level control mode - Controlled by 4-20mA hydrostatic level transducer and optional backup high and low level float switches, submerged in a tank or pit
  • Tank top up valve control - Tops up tank with mains water when normal inflow of rain or treated water into tank does not keep up with demand (Specific to level control)
  • Maintain minimum level - Ensures minimum tank level is maintained (Specific to level mode, empty direction)
  • Pressure control mode - Controlled by 4-20mA pressure transducer and optional high and low pressure switches
  • Jacking pump control - Pump 1 will always be the first to wake from sleep and main pumps will start if unable to keep up with demand (Specific to pressure mode)
  • Mains bypass valve control - Switches to mains water to bypass supply tank when pumping system is out of water or in fault condition (Specific to pressure mode)
  • Sleep assist speed minimise - When the system is at setpoint and pump speed is constant due to no demand for water, the system will slowly drop the pump speed, helping it to go to sleep sooner (Specific to pressure mode)
  • Sleep assist boost - When the system is nearing setpoint and there is no demand for water, the system will boost the pressure before going to sleep so it can sleep for longer, reducing pump cycling (Specific to pressure control)
  • Pipe fill - If the system wakes up and pressure is low, pipe fill runs a single pump to gently build pipe pressure and shuts the pump down if unable to build pressure within 10 minutes (Specific to pressure mode)
  • Temperature control mode - Controlled by 4-20mA temperature transducer and optional backup high and low temperature thermostats
  • Sleep modes - Sleep can be enabled to allow pumps to sleep when setpoint is reached, or disabled so one pump is always running to circulate water (specific to temperature mode)
  • IP44 rated, powder-coated mild steel enclosure with removable gland plate, integral ventilation and thermostatically controlled fan
  • Pad-lockable mains power isolator switch
  • Circuit breaker protected low voltage control and input circuitry
  • Individual pump circuit breaker protection

  • 1-6 pump outputs (230Vac three phase for both 1 & 3 phase versions)
  • BMS volt free output for common fault
  • Output for solenoid valve available upon request
  • Modbus RTU Serial RS485 connections for SCADA
Interface Features
  • Main screen with system status, auto/off/manual modes

  • Alarms screens with mute/reset, date & time stamped historical faults
  • Logged data with system event & fault counts, pump starts, run hours
  • Analog feedback value trend graph
  • Streamlined, user friendly system setup process
  • System diagnostics for easy fault finding, factory reset
