Warrick 26B1A0E Control

The Warrick 26B1A0E is a technical-grade liquid level control engineered for low water cutoff protection in demanding HVACR and industrial environments. Operating on a 120Vac supply voltage, this direct-acting series 26 board utilizes a 10,000 ohm sensitivity threshold to monitor conductive fluids with precision. The unit is designed for panel mount integration using a 1/16" panel standoff, making it an ideal choice for custom control cabinets where an enclosure is not required. It features a built-in 3-second time delay to filter out turbulence and prevent nuisance tripping, ensuring the SPDT relay (Single Pole Double Throw) accurately manages the circuit. A critical safety feature is the manual reset functionality, which includes a power outage feature to ensure the system remains in a safe state until manually cleared by a technician after a low-water event or power loss.

Technical Benefits for Contractors

• Reliable False-Trip Prevention: The integrated 3-second delay ignores temporary splashes or surges, protecting the boiler low water cutoff sequence.
• Enhanced Safety Logic: The manual reset with power outage feature ensures the system does not automatically restart in a dry-fire condition.
• Simplified Field Wiring: Equipped with spade terminals for fast, secure connections during conductance probe wiring.
• Direct Compatibility: The 26B1A0E (also identified as 26B1AOE) is a drop-in replacement for specific OEM Gem-Sen or Warrick Series 26 control boards.
• Versatile Circuit Control: The SPDT relay provides both normally open and normally closed contacts for flexible alarm or pump-stop configurations.

Common Questions

What is the difference between 26B1A0E and 26B1AOE?
They are identical part numbers; the "0" (zero) and "O" are often used interchangeably in field service catalogs for this specific Warrick liquid level control.

Does this board require a specific sensor?
This control is designed to work with conductance-actuated liquid level probes. Ensure the fluid resistance matches the 10,000 ohm sensitivity for proper bridge activation.

Can this be used for high-water alarms?
While primary for low water cutoff, the SPDT relay allows it to be wired for various high or low-level logic, provided the direct-acting mode of operation fits your sequence.
