Warrick DFM1C0 Control

The Warrick DFM1C0 is a specialized Dual Function Level Control designed for multi-state liquid level management in demanding HVACR and industrial processes. This conductive level controller utilizes a 120 VAC supply to manage two independent functions, typically configured for pump down and high-level alarm or low-water cutoff sequences. Built with a robust plug-in design, the DFM1C0 simplifies installation and field replacement, reducing downtime for contractors. Its dual-channel circuitry eliminates the need for two separate control units, saving enclosure space and reducing wiring complexity. This liquid level relay is engineered to work seamlessly with Warrick electrode probes and sensor fittings, providing reliable, solid-state switching without moving parts. By monitoring electronic conductivity, it ensures precise actuation even in turbulent tanks, making it a standard choice for boiler feed systems, condensate return tanks, and sump monitoring applications where accuracy is non-negotiable.

• Reduced Footprint: Consolidates two independent control functions into a single octal-style plug-in module.
• Industrial Build: Solid-state reliability provides superior longevity compared to mechanical float switches in high-cycle environments.
• Application Versatility: Suitable for a wide range of conductive liquids including water, wastewater, and mild chemical solutions.
• Fail-Safe Design: Engineered to provide consistent switching logic to prevent tank overflows or pump dry-run conditions.
• Easy Diagnostics: Simplified wiring schematic allows for rapid continuity testing and troubleshooting of the sensor circuit.

Can the DFM1C0 be used with single-probe sensors?
The unit is designed for use with multiple conductivity probes to establish high and low setpoints; usually, a common probe plus individual probes for each level function are required for proper operation.

Is this controller compatible with non-conductive liquids?
No, like all Warrick conductive controls, this unit requires the medium to have a minimum level of conductivity to complete the sensing circuit between electrodes.

What is the primary advantage of the plug-in base?
The 8-pin or 11-pin base allows for rapid "hot-swapping" of the control module without disconnecting field wiring, which is critical for maintaining uptime in mission-critical HVACR systems.
