Warrick DFL1A0K Board

The Warrick DFL1A0K is a professional-grade 120V dual function control board engineered for precise liquid level management in demanding HVACR and industrial environments. This open-circuit board configuration utilizes 10K Ohm sensitivity and inverse acting logic, making it a reliable solution for boiler feedwater control and low-water cutoff (LWCO) applications. As a dual function level control, the Warrick DFL1A0K integrates two independent sensing functions into a single 1/16-inch standoff panel mount footprint, streamlining cabinet space and reducing wiring complexity for contractors. The secondary circuit delivers a safe 2.3 VAC RMS to the probes, minimizing electrolysis and extending the operational life of your electrode sensors. Equipped with a dedicated manual reset function and a power outage feature, this dual function board ensures system safety by requiring a physical interaction after a trip condition, preventing automatic restarts in critical low-water scenarios.

• Dual-Function Versatility: Manages both single-level and differential-level operations on a single board.
• Enhanced System Safety: Features a manual reset button to ensure controlled recovery after low-water deactivation.
• Industrial Durability: Solid-state design with an ambient temperature rating of -40°F to +150°F for rigorous mechanical room conditions.
• Standardized Integration: Compact 1/16-inch panel standoff style with 1/4-inch male quick-connect terminals for power and 3/16-inch for probes.
• Code Compliance: Designed to meet CSD1 requirements and UL-353 Limit Control standards for 120V supply voltages.

How do I test the LLCO circuit on the Warrick DFL1A0K?
On models equipped with the test feature, holding the reset button for 3 seconds simulates a dry probe condition, allowing you to verify the LLCO trip logic without draining the system.

What is the difference between direct and inverse operation for this board?
The Warrick DFL1A0K typically utilizes inverse acting logic for low-water cutoff applications, where the relay de-energizes upon sensing a low-level condition to protect equipment.

Can I use this board for pump-down applications?
Yes, the dual-function nature of the DF series allows for varied wiring configurations, including high-level/low-level differential control or simple pump-down sequences when paired with compatible probes.
