MATelec HydroWHIZ FPC-63220-I Mild Steel Three Phase 15 kW Variable Speed Two Pump Controller

Suitable for two-pump installations in water transfer, stormwater and sewage applications, the HydroWHIZ FPC-63220-I provides variable-speed regulation with level, pressure and temperature operating modes. Its 15 kW VSD rating runs from a three-phase 400 Vac supply, matching motor speed to system demand.

With automatic duty alternation and bumpless transfer, the controller distributes operating hours evenly across the two pumps. Additional pumps are brought into operation as demand increases to maintain the selected setpoint, then removed from service when they are no longer required. Pumps are started and stopped in sequence to reduce excessive current draw and minimise water surge or hammer. Sleep Assist Boost and Pipe Fill help reduce pump cycling and gently build pressure in empty pipelines.

Proportional speed control responds to level or temperature signals, while PID control adjusts pressure with configurable proportional and integral values. The enclosure is IP44-rated mild steel with a thermostatically controlled fan and removable gland plate for field cabling.

System monitoring and configuration are handled through a colour touchscreen HMI, with Modbus RTU RS485 providing connectivity to SCADA systems. The touchscreen provides system and individual pump status, operating modes, logged information and trend graphs. A volt-free common fault relay offers remote alarm signalling.

Protection features include 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. Pump limiting can be configured where maximum flow or power requirements need to be kept within defined system limits.
