Freshwater Pump Controller

Control and manage your freshwater pump

Designed to control the freshwater pump using a high-quality pressure sensor, this device boasts intelligent features, enhancing pump reliability and noise reduction. With an intuitive interface, it requires no specialized tools for calibration. The FWPC offers two PWM-controlled outputs, an audible warning, and arrives ready-to-install with necessary accessories. Energy efficient, it's also "MRS Cloud Connect" compatible. If the sensor malfunctions, the system relies on the pressure switch for operation.

Freshwater Pump Controller Solution
  • Easy calibration, no specialized tools or software is required.
  • FWPC supports two high current outputs with pressure switch. 
  • The standard system has single pump output and audible warning device.
  • Being a plug-and-play solution, FWPC has all the necessary accessories from the box, cable harness, audible warning device, fuse connection kit including butt connectors, etc.
