Raypak 007228F Sensor

The Raypak 007228F Remote Sensor is a critical field-service component designed for Low Water Cut-Off (LWCO) safety circuits in high-efficiency hydronic systems. As a genuine OEM replacement part, this sensor provides precise electrode-based water level monitoring to prevent "dry fire" conditions that can lead to catastrophic heat exchanger failure. It is engineered for seamless integration with Raypak boiler models including the H-1259B, H-1529B, and H-1799B series. By delivering real-time continuity data to the LWCO control module, the 007228F sensor ensures the gas valve circuit remains energized only when the probe is fully submerged, maintaining the operational integrity of the primary loop.

This remote-mount probe is built to withstand the rigorous thermal cycling and pressure fluctuations common in commercial and industrial hot water boilers. Professionals choose the Raypak 007228F sensor to ensure the internal conductivity signals match the factory calibration of the electronic LWCO system, avoiding the nuisance tripping or delayed response times often associated with non-OEM alternatives. Whether you are performing a preventative maintenance overhaul or troubleshooting a system lockout, this 007228F remote sensor for LWCO is the technician's standard for restoring safety compliance and unit reliability.

• Prevents Dry Firing: Shuts down the heating cycle immediately if water levels drop below the probe point, protecting the heat exchanger.
• OEM Compatibility: Guaranteed to interface correctly with Raypak H-Series boiler control boards and LWCO kits.
• High-Durability Construction: Materials selected for long-term resistance to scale buildup and corrosion in hydronic applications.
• Precise Signal Accuracy: Maintains steady millivolt or conductivity readings to prevent false "low water" error codes.
• Simple Field Replacement: Standardized threading and terminal connections allow for fast bolt-on installation during service calls.

What boiler models is this sensor compatible with?
The Raypak 007228F is primary equipment for the Raypak H-Series, specifically the H-1259B, H-1529B, and H-1799B models using remote LWCO safety systems.

How do I test if the 007228F sensor is faulty?
Use a multimeter to check for continuity between the probe and the boiler chassis when the tank is full. If there is high resistance while the probe is submerged, it typically indicates scale buildup or internal failure.

Can I use this as a replacement for a direct-mount LWCO?
No, this is a remote sensor designed specifically for systems where the probe is separated from the control module. Check your existing LWCO kit SKU to ensure a matches-for-match replacement.
