Warrick 26C1D0P Control

The Warrick 26C1D0P Control is a professional-grade conductive liquid level control specifically engineered for boiler low water cutoff (LWCO) protection. This 120Vac, direct-acting level controller features a factory-set 26,000 ohm sensitivity, making it the industry standard for sensing condensate and natural water levels while preventing nuisance trips. Built on an open-board design with a retrofit standoff style, this unit integrates seamlessly into existing panels using spade terminals and the included retrofit plate. The secondary 12VAC sensing circuit ensures safe electrode operation, while the SPDT relay provides flexible 10A resistive switching for burners or alarms. To ensure system stability during turbulent water conditions, the Warrick 26C1D0P includes a built-in 3-second time delay. This specific model supports manual reset with a power outage feature, allowing the control to automatically resume operation if power is restored while water is at a safe level, but requiring manual intervention via the remote mount normally closed pushbutton if a true low-water condition occurs. This control is fully UL 353 recognized and meets CSD-1 requirements for commercial boiler installations.

• CSD-1 Compliance: Meets essential safety standards for boiler low water cutoff applications in commercial and industrial environments.
• 26K Ohm Sensitivity: Optimized for standard water conductivity to provide reliable liquid level sensing without ghost-trips from high humidity.
• Integrated Safety Logic: Features manual reset functionality to ensure an operator inspects the system after a low-water event.
• Power Outage Recovery: The power outage feature prevents unnecessary lockouts after momentary supply interruptions, provided water levels remain safe.
• Retrofit Ready: Designed with standoff mounting and a specialized retrofit plate for fast installation in existing control cabinets.

Common Questions

How does the manual reset interact with the power outage feature?
If power is lost but the water level is still above the probe when power returns, the Warrick 26C1D0P will automatically reset. However, if the water level drops below the probe, the manual reset pushbutton must be depressed to restart the system, ensuring the low water cutoff logic is maintained.

Can I use this control for pump-up or pump-down applications?
This direct-acting control is primarily designed for low water cutoff and point-level service. While the SPDT relay can switch loads, its logic is set for direct operation, meaning the relay de-energizes when the liquid level falls below the sensor probe.

What type of wiring is recommended for the remote probes?
For optimal signal integrity and to prevent under-sensing, use MTW or THHN #14 or #16 AWG wire. Ensure the distance between the Warrick level control and the electrodes does not exceed manufacturer specifications for 26K ohm sensitivity.
