The Warrick 26C1D1 LWCO is a professional-grade conductivity-based liquid level control engineered for critical low-water cutoff protection in boiler systems. This 120VAC-powered unit features a precise 26Kohm sensitivity rating, making it ideal for monitoring water levels with moderate resistance and ensuring consistent relay actuation without nuisance tripping. Housed in a durable NEMA 1 enclosure, this controller is designed for secure indoor installation and provides reliable secondary voltage of 12 VAC to the probes to minimize electrolysis and extend electrode life. As a direct replacement for the 26C1C1, the 26C1D1 integrates seamlessly into existing setups, meeting CSD1 requirements for boiler safety. Its solid-state design and SPDT relay output (rated for 10A resistive) provide the rugged dependability required by mechanical contractors in steam generators, sterilizers, and hydronic heating applications where maintaining a minimum water level is essential for equipment safety. Key Benefits: Direct Retrofit Compatibility: Engineered to provide a standard drop-in replacement for the Warrick 26C1C1, reducing downtime during field maintenance. CSD1 Compliance: Meets essential industrial standards for boiler low water cutoff (LWCO) protection, ensuring code-compliant installations. Robust Signal Integrity: The 26K ohm sensitivity ensures accurate level detection in various water qualities while the NEMA 1 enclosure protects internal solid-state components. Electrolysis Reduction: Uses low AC voltage on the probe circuit to prevent electrode plating and degradation, maintaining long-term sensor accuracy. Versatile Relay Output: Features 120V primary supply voltage with high-capacity 10A contacts suitable for alarm circuits or direct burner control. Common Questions: Is this unit compatible with my existing probes? Yes, the 26C1D1 works with standard Warrick Series 3 conductivity probes and is designed to replace the 26C1C1 model in most low-water cutoff applications. Can this be mounted outdoors? This specific model comes in a NEMA 1 enclosure, which is intended for indoor use to protect against falling dirt and contact with equipment. For outdoor or wash-down environments, a NEMA 4X housing would be required. Does this include a manual reset? The 26C1D1 typically operates in direct mode for level control; always verify your specific wiring configuration to ensure the system meets local safety codes for manual vs. automatic reset functionality.
