Warrick 26C1B0E Control

The Warrick 26C1B0E is a heavy-duty liquid level control designed for precise low water cutoff and pump-up/pump-down applications. Operating on a 120Vac supply voltage, this Series 26 conductivity-based controller features a 26,000 ohm sensitivity and direct acting mode, making it ideal for maintaining boiler water levels and preventing dry-fire conditions. The SPDT relay configuration provides one normally open and one normally closed contact for versatile field wiring. Engineered with a built-in 3 second time delay, the unit prevents rapid cycling and nuisance tripping caused by surface turbulence or splashing. This 1/8" panel standoff style board includes a manual reset feature with a power outage memory, ensuring the system remains locked out after a low-water event until manually cleared by a technician. The open-board design with spade terminals allows for rapid integration into existing control cabinets where space and efficiency are critical for contractors.

• Enhanced System Reliability: The conductivity probe control eliminates moving parts, reducing mechanical failure points in steam and hydronic systems.
• Fail-Safe Operation: The manual reset with power outage feature ensures that critical low-water conditions are addressed by a technician before the burner resumes operation.
• Stable Signal Processing: Integrated 3-second time delay filters out electrical noise and physical water surging for a consistent control signal.
• Direct Board Replacement: Standard panel standoff mounting and spade terminal connections simplify the replacement of legacy Series 26 control modules.

Common Technical Questions

How do I wire the manual reset circuit on the 26C1B0E?
The Warrick Series 26 manual reset utilizes the dedicated reset button wiring on the board; once a low-water trip occurs, the relay latches open until the water level is restored and the reset circuit is closed, even if the 120V power supply is cycled.

What is the purpose of the 26,000 ohm sensitivity rating?
The 26,000 ohm sensitivity defines the maximum resistance the control can detect between the probe and the common ground. This high-sensitivity level is specifically calibrated for standard tap water and boiler water applications to ensure a reliable conductive path.

Can this board be used for high-level alarm applications?
While primarily used for low water cutoff, the SPDT relay and direct acting logic allow it to be configured for high-level detection by utilizing the opposite contact state in conjunction with your probe placement.
