MATelec HydroWHIZ FPC-63320-F Mild Steel Three Phase 5.5 kW Variable Speed Three Pump Controller

Pressure boosting, water transfer and hot water circulation with three pumps are managed by the HydroWHIZ FPC-63320-F, providing variable-speed regulation with level, pressure and temperature operating modes. Its 5.5 kW VSD rating runs from a three-phase 400 Vac supply, matching motor speed to system 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. In pressure-control modes, Pipe Fill builds line pressure while jacking pump control brings Pump 1 out of sleep first, activating the main pumps when necessary.

Proportional speed control responds to level or temperature changes, with PID control maintaining steady pressure. The IP44 powder-coated mild steel cabinet includes integral ventilation and a removable gland plate.

A colour touchscreen HMI provides system and individual pump status, operating modes, logged events and diagnostic functions. Modbus RTU RS485 supports SCADA integration, and a 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.

Features

• 4-20mA analogue input compatible with level, pressure or temperature transducers
• Eight digital 24Vdc inputs for backup float switches, pressure switches or thermostats
• Jacking pump control brings Pump 1 out of sleep first, with the main pumps starting when it can no longer keep up with demand
• Removable gland plate
• Colour touchscreen HMI for monitoring, diagnostics and alarm logging
• Sleep Assist Boost temporarily increases pressure before sleep, allowing a longer sleep period and reducing pump cycling
• Individual pump circuit breaker protection
