Warrick DFC1D0 Control Board
The Warrick DFC1D0 Control Board is a high-performance Series DF dual function conductivity level control designed for demanding HVACR and industrial liquid management. Operating at 120 VAC, this retrofit level control board provides a direct-action solution with a factory-set 26,000 ohm sensitivity, making it ideal for monitoring condensate tanks, boiler feed systems, and cooling towers. Its solid-state design ensures reliable probe conductivity detection without the mechanical failures associated with float-based switches. This open board control style features spade terminals for efficient field wiring and occupies a compact footprint, allowing for seamless integration into existing control panels. The Warrick DFC1D0 manages two independent functions—typically one single-level operation and one differential-level operation—to prevent dry-run conditions or overflows. Built for the professional contractor, this solid-state level control offers 10A resistive contact ratings and includes UL Limit Control compliance for safety-critical installations.
Key Benefits for HVACR Applications- Dual Function Versatility: Manages both differential and single-level control on a single retrofit board, reducing the need for multiple components.
- Enhanced System Protection: Prevents dry-run and overflow issues in boilers and cooling towers through precise conductivity sensing.
- Rugged Solid-State Reliability: Electronic sensing eliminates moving parts, providing a significantly longer mechanical life than traditional float switches.
- Technical Integration: Spade connection terminals and a standard 120V supply voltage simplify the replacement of legacy series controls.
How do I troubleshoot "over-sensing" on the DFC1D0 board?
Over-sensing often occurs if the 26K ohm sensitivity is too high for the medium, or if moisture has bridged the probe terminals. Ensure probe wires are not run in the same conduit as high-voltage lines to prevent voltage noise from triggering false level indications.
Can this board be used for low-water cutoff (LWCO) applications?
Yes, the Warrick DFC1D0 is commonly used as a LLCO (Low Level Cutoff) control. For these installations, terminal 3 and 4 are typically used to manage the relay state based on electrode contact, often requiring a manual reset if specified by local boiler codes.
What wire type is recommended for the probe connections?
For optimal signal integrity and to minimize capacitance interference, use 14 or 16 AWG MTW or THHN wire. Always keep probe leads as short as possible when working with high-sensitivity controls.
