MATelec HydroWHIZ FPC-63220-K Mild Steel Three Phase 22 kW Variable Speed Two Pump Controller

Two-pump pressure boosting, water transfer and hot water circulation applications are addressed by the HydroWHIZ FPC-63220-K, which delivers variable-speed regulation with level, pressure and temperature operating modes. Its 22 kW VSD rating runs from a three-phase 400 Vac supply, with speed adjusted according to system demand.

The control logic supports duty alternation, staging and bumpless transfer to balance operation across the two pumps and maintain stable system performance. Additional pumps are brought into operation as demand increases to maintain the selected setpoint, then removed from service when they are no longer required. Pressure-control functions include Pipe Fill for gentle line pressurisation and Sleep Assist Boost for extended sleep periods during low demand.

Jacking pump control brings Pump 1 out of sleep to handle low demand, activating the second pump only when necessary. Housed in an IP44 mild steel cabinet with thermostatic fan ventilation, the panel includes a colour touchscreen HMI for local monitoring and programming. The touchscreen provides system and individual pump status, operating modes, logged events and diagnostics.

Standard Modbus RTU RS485 communication enables integration with SCADA and BMS platforms, with a common fault relay providing remote alarm notification. Protection features cover 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

• Thermostatically controlled fan provides enclosure ventilation
• Removable gland plate
• User setup and diagnostics managed through colour touchscreen HMI
• Sleep Assist Boost temporarily increases pressure before sleep, allowing a longer sleep period and reducing pump cycling
• Individual pump circuit breaker protection
• Pump anti-seize protection runs pumps periodically during low use to help prevent seizing
• Jacking pump control brings Pump 1 out of sleep first, with the main pumps starting when it can no longer keep up with demand
