Xylem’s McDonnell & Miller Series 67 Electronic Conversion Adapter Kit enables the conversion of a traditional mechanical low water cut-off (LWCO) into a modern, field-configurable electronic monitoring and control system using the boilerwize® (FPC-1000) low water cut-off. 

  • Modernize without replacement: Upgrade existing Series 67 installations to field-configurable electronic control while retaining the installed body.
  • Enhanced reliability: Eliminates mechanical wear components, reducing potential failure points.
  • Improved safety & control: Precise water level monitoring with the boilerwize® FPC-1000 electronic LWCO.
  • Reduced maintenance: Self-cleaning probe minimizes service requirements.
  • Quick installation: Contains the components needed for a fast, seamless retrofit.

Designed for straight forward installation, the boxed kit contains the components needed for a fast, cost-effective upgrade, while retaining the existing boiler tapping and piping configuration.

Mechanical LWCO: 
Moving parts, regular maintenance, moderate accuracy, limited diagnostics.

Electronic LWCO: 
No moving parts, low maintenance, high accuracy, advanced diagnostics.

The boilerwize FPC-1000 is a versatile, field-configurable LWCO for steam and hot water boilers. It can be configured for 24V or 120V operation and automatic or manual reset. The FPC-1000 provides protection against low water conditions and can be used as a primary or secondary LWCO device in residential, commercial, and industrial applications.
