Warrick 26MC1A0Z Control

The Warrick 26MC1A0Z Control is a precision low water cutoff plug-in module designed for critical boiler safety and industrial fluid management. Operating with a 26,000 ohm sensitivity, this direct acting solid-state controller utilizes the liquid’s natural conductivity to facilitate reliable switching with no moving parts in the sensing circuit. This specific configuration features a manual reset with a power outage feature, ensuring the system remains in a safe state following a low-water trip, even if power is cycled, until a technician manually clears the condition. The integrated test feature allows for routine safety verification of the LLCO circuit without the need to physically drain the vessel, minimizing downtime during inspections.

Built for professional integration, the unit utilizes a standard 11-pin octal socket style with a screw connector socket for secure terminations. The SPDT relay provides powered contacts (1 Normally Open/1 Normally Closed), streamlining 120Vac control loops by eliminating the need for separate jumpers to the common terminal. With its open-board design and UL 353 limit control recognition, the 26MC1A0Z is the standard choice for contractors requiring CSD-1 compliance in hydronic and steam applications.

Key Benefits

• Direct Acting Reliability: Optimized for single-level service and low-water cutoff protection with a standard 3-second time delay to prevent nuisance tripping.
• Integrated Safety Logic: The manual reset prevents automatic restarts into a dry boiler, while the power outage feature ignores brief electrical interruptions.
• Simplified Field Maintenance: The test feature enables rapid diagnostic verification of the liquid level control logic via a simple pushbutton interface.
• Professional Grade Hardware: Features an 11-pin octal socket and durable solid-state components for long-term survival in high-ambient HVACR environments.

Common Questions

Does this module require a specific type of probe?
The Warrick 26MC1A0Z is compatible with any standard conductivity-based Warrick probes and fittings, provided the fluid resistance does not exceed the 26K ohm factory sensitivity setting.

Can I use this for automatic refill applications?
No, this specific model is a direct acting module typically used for low water cutoff. For refill or "pump-up" applications, an inverse acting control or a differential-level relay is required.

What does it mean that the contacts are "powered"?
Powered contacts mean the 120Vac supply voltage is internally linked to the relay common. This allows you to power a burner circuit or alarm directly from the output pins without additional external wiring.
