Warrick 26C1C0C Control

The Warrick 26C1C0C is a precision-engineered liquid level control designed specifically for low-water cutoff applications in boilers and commercial HVACR systems. Operating on a 120Vac supply voltage, this direct-acting level controller features a fixed 26,000 ohm sensitivity, making it the industry standard for sensing conductive liquids in demanding environments. This open board control utilizes a screw mount standoff style for easy integration into existing enclosures. The internal SPDT relay provides one normally open and one normally closed contact, rated for heavy-duty switching. To prevent nuisance tripping caused by turbulence or surging, the board includes a built-in 3-second time delay. This specific model requires a manual reset and a remote mount normally closed pushbutton, ensuring a technician inspects the system before operation resumes after a low-water event. Spade terminals facilitate quick and secure wiring for field installations and retrofits.

Key Benefits for Technicians

• Solid-state reliability eliminates mechanical failure points common in traditional float-style switches.
• Direct acting mode ensures immediate response when the probe loses contact with the liquid.
• Manual reset functionality is essential for compliance in critical boiler safety and low water cutoff sequences.
• Compact open board design fits easily into tight control panels using standard screw mount standoffs.
• 26K Ohm sensitivity calibrated for high-purity water and various conductive liquid applications.

Common Installation Questions

What type of pushbutton is required for the manual reset?
The Warrick 26C1C0C requires a remote mount normally closed pushbutton for the manual reset circuit. Interrupting the circuit restores power to the control relay once the liquid level covers the probe.

Can this board be used for high-level alarms?
While often used for LWCO, this direct acting control can be configured for high-level detection, though the manual reset logic is specifically optimized for safety-critical low-level applications.

What probe hardware is compatible with this series?
This control is compatible with all Warrick electrode and probe fittings, provided the liquid conductivity falls within the 26,000 ohm threshold.
