Warrick 26C3A0 Control

The Warrick 26C3A0 is a high-sensitivity liquid level control engineered for low water cutoff applications in boilers and commercial HVACR systems. Operating on a 24Vac supply voltage, this conductive level controller utilizes a 26,000 ohm direct acting sensitivity to manage fluid levels with precision. The SPDT relay configuration provides both 1 NO and 1 NC contact, rated for heavy-duty switching roles in pump-up or pump-down sequences. Designed for space-saving panel integration, the 1/16" panel standoff mounting style allows for clean installation on a sub-panel without a dedicated enclosure. Field technicians will value the built-in 3 second time delay, which prevents boilers and pumps from short-cycling due to surface turbulence or liquid level surges. This open-board control features spade terminals for secure, vibration-resistant electrical connections, making it a reliable drop-in replacement for standard Warrick series 26 industrial probes and sensors.

Key Specifications and Benefits

• 26K Ohm Sensitivity: Optimized for high-resistance liquids and refined monitoring tasks.
• Direct Acting Logic: Triggers the relay when the liquid rises to touch the probe.
• Internal Time Delay: Eliminates nuisance tripping caused by wave action or turbulence.
• SPDT Relay: Provides versatile switching options for load and alarm circuits.
• Compact Open-Board Design: Facilitates easy integration into existing control cabinets.

Common Technical Questions

What is the maximum ambient temperature for this control board?
The Warrick 26C3A0 is typically rated for operation in environments ranging from -40°F to +150°F, making it suitable for mechanical rooms and boiler environments.

Can this be used for sewage or wastewater applications?
While the 26,000-ohm sensitivity is ideal for cleaner water, ensure the probe conductivity matches the specific gravity and resistivity of the fluid to prevent electrode fouling.

How do I wire the Warrick 26C3A0 for low water cutoff?
Utilize the SPDT relay terminals and spade connectors to break the burner circuit or trigger an alarm when the liquid level falls below the probe tip.
