Warrick 26C1C0 Control

The Warrick 26C1C0 Control is a reliable low water cutoff control board designed for high-performance liquid level monitoring in steam boiler and hydronic systems. Operating on a 120Vac supply voltage, this direct acting sensitivity module utilizes a 26,000 ohm threshold, making it ideal for sensing conductive liquids across various HVACR applications. The SPDT relay configuration (1 NO/1 NC) provides versatile switching capabilities for pumps, valves, or alarms, while the built-in 3 second time delay effectively prevents nuisance cycling caused by turbulence or surging within the vessel. This screw mount standoff style board features spade terminals for rapid field wiring and is designed for open-chassis installation without an enclosure. Whether you are replacing a Warrick series 26 unit or performing a new boiler installation, the 26C1C0 ensures steady conductivity probe regulation and system protection.

• Precise 26K Ohm Sensitivity: Calibrated for standard water conductivity to ensure accurate low water detection.
• Anti-Short Cycle Protection: Integrated 3-second delay ignores momentary level fluctuations to protect contactors and motors.
• Flexible SPDT Contacts: Rated for heavy-duty switching, allowing for simultaneous control of primary loads and secondary status indicators.
• Compact Standoff Mounting: Small footprint allows for easy integration into existing control cabinets or burner harnesses.
• Direct Acting Reliability: The Warrick 26C1C0 de-energizes upon sensing a low water condition for fail-safe operation.

How do I wire the Warrick 26C1C0 for a low water cutoff application?
Connect the 120V hot lead to the identified supply terminal and the neutral to the common. The probe lead connects to the sensor terminal, while the SPDT contacts are wired in series with the burner circuit or magnetic starter to break the circuit when the liquid falls below the probe level.

Can this board be used for high-level alarm functions?
While this specific model is direct-acting for low-level protection, its SPDT relay allows you to utilize the normally closed contact for high-level signaling, provided the 26,000-ohm sensitivity matches the fluid profile.

What is the purpose of the 3-second delay on the 26C1C0?
The delay prevents the relay from "chattering" when water levels are unstable at the probe tip, ensuring the system only reacts to sustained changes in liquid levels rather than splashing or foam.
