Warrick 26C1D1F LWCO

The Warrick 26C1D1F is a heavy-duty 120V low water cut-off (LWCO) liquid level control designed for boiler feed and burner protection applications. As a conductivity-based level switch, it utilizes the Series 26 controller platform, featuring a normally closed (NC) contact configuration and an integrated reset push button. This unit is housed in a robust NEMA 1 enclosure, ensuring reliable performance in commercial and industrial settings. The 26C1D1F functions as a direct field replacement for legacy models including the 26C1A1F, 26C1C1F, and 26C1D0F, allowing for seamless integration into existing Warrick liquid level control systems without extensive rewiring. Engineered for high-sensitivity detection, this controller maintains precise signal integrity even in high-temperature environments, providing a critical safety layer for steam boilers and hydronic systems. Its solid-state design eliminates moving parts, significantly reducing downtime and ensuring consistent boiler safety control operation.

• Universal Field Compatibility: Designed to replace 26C1A1F, 26C1C1F, and 26C1D0F models efficiently.
• Integrated Manual Reset: Features a dedicated push button to meet code requirements for manual restart after a low water event.
• Enhanced Reliability: Solid-state circuitry prevents mechanical failure common in float-style switches.
• Simplified Installation: Standard NEMA 1 housing provides easy access to terminal blocks for rapid field wiring.
• Voltage Precision: Optimized for 120VAC power supplies, ensuring stable logic performance during voltage fluctuations.

How do I wire the Warrick 26C1D1F for a burner circuit?
The unit features NC (Normally Closed) contacts that open upon sensing a low water condition. Ensure the burner circuit is wired in series with the control contacts to provide an immediate safety shutdown.

Can the sensitivity be adjusted for different water types?
Yes, the Series 26 controller is factory-calibrated for standard conductivity levels but can be field-tuned if dealing with high-purity water or specific chemical additives that affect electrical resistance.

What is the primary difference between this and the 26C1D0F?
The 26C1D1F includes a manual reset push button and a NEMA 1 enclosure, whereas the D0F variant typically lacks the reset feature required by many current boiler safety codes.
