MATelec HydroWHIZ FPC-63220-C Mild Steel Three Phase 2.2 kW Variable Speed Two Pump Controller

Two-pump water transfer, stormwater and sewage applications are addressed by the HydroWHIZ FPC-63220-C, which provides variable-speed regulation with level, pressure and temperature operating modes. Its 2.2 kW VSD rating runs from a three-phase 400 Vac supply, matching motor speed to demand.

Control logic allows selection between level, pressure or temperature modes, with staggered pump starting reducing excessive current draw and water surge or hammer. Additional pumps are brought into operation as demand increases to maintain the selected setpoint, then removed from service when they are no longer required. Sleep Assist Speed Minimise and Sleep Assist Boost extend sleep periods and reduce pump cycling, with staggered start-stop delays reducing water surge.

Housed in an IP44 mild steel enclosure with thermostatically controlled fan, the panel includes a colour touchscreen HMI with comprehensive diagnostics, pump circuit breakers and a lockable isolator switch. The touchscreen provides system and individual pump status, operating modes and logged information. A volt-free common fault relay provides BMS signalling, and Modbus RTU RS485 supports SCADA integration.

Configurable protection covers high and low limits, no-flow and feedback-signal faults. VSD and system protection functions monitor operating conditions and provide configurable responses to faults such as overload, pressure, level, temperature, no-flow and feedback-signal conditions. Manual operation is available for both the system and individual pumps, with a 10-minute timeout returning the controller to automatic operation.

Features

• Pipe Fill gently builds pipe pressure during startup
• Integrated RS485 serial communication supports Modbus RTU for SCADA connection
• Padlockable mains isolator switch allows the incoming power supply to be physically isolated during servicing and maintenance
• Circuit breaker protected low-voltage control and input circuitry
• Individual pump circuit breaker protection
• Sleep Assist Boost temporarily increases pressure before sleep, allowing a longer sleep period and reducing pump cycling
• Colour touchscreen HMI simplifies on-site commissioning and alarm tracking
