Warrick 26B3A0E Control

The Warrick 26B3A0E (often identified as 26B3AOE) is a heavy-duty series 26 liquid level control designed specifically for low water cutoff protection and single-level service. Operating on a 24Vac supply voltage, this control utilizes a 10,000 ohm sensitivity rating and a direct acting mode of operation, ensuring precise conductance-actuated response for boiler and storage tank applications. Built on a 1/16" panel standoff style open board, it fits tight enclosures where space is at a premium. The integrated SPDT relay provides versatile switching logic, while the built-in 3 second time delay prevents rapid cycling due to turbulence or surging. A critical safety feature for field technicians is the manual reset with power outage feature, which prevents automatic restarts after a low-water condition or power loss. Connections are streamlined via standard spade terminals, facilitating fast installation or replacement in commercial HVACR systems.

Key Benefits

• Ensures system safety with a manual reset feature that complies with stringent low water cutoff requirements.
• Reduces nuisance tripping in turbulent tanks through a factory-set 3-second time delay.
• Compatible with a wide range of Warrick dry-type probes and electrode sensors for customized level monitoring.
• Compact open board design allows for multi-zone mounting within a single control panel.
• Reliable SPDT contact configuration enables simultaneous control of both an alarm circuit and a burner or pump circuit.

Common Questions

What is the difference between the 26B3A0E and 26B3AOE?
These two part numbers refer to the exact same Warrick Series 26 control; the "0" (zero) and "O" (letter) are used interchangeably in various procurement databases.

Does this board require a specific probe sensitivity?
Yes, this specific model is calibrated for 10,000 ohms, making it ideal for standard potable water and high-conductivity liquids.

How does the power outage feature affect the manual reset?
In the event of a power failure, the Warrick 26B3A0E remains in a lockout state until the manual reset button is depressed, ensuring a technician inspects the system before resuming operation.
