Taco 120V Low Water Cutoff, 3/4″ NPT Probe, Manual Reset, Foam Compensating
The Taco LWCO provides reliable protection for all types of boilers, from small residential hot water boilers to large industrial steam boilers. The boiler’s minimum safe operating water level is specified by each manufacturer. Should the water level dip below that specified level, heat will accumulate quickly causing significant damage to the boiler and a potential external safety hazard.
For accurate and dependable boiler protection, our Low Water Cutoff (LWCO) features the simplicity, reliability and unmatched quality you’ve come to expect from Taco Electronic Controls. The LWCO is a probe style, microprocessor based control that detects the fluid level in hot water and steam boilers. Patented signal processing technology, external LEDs and simplified wiring make installation and testing a snap.
The LF model is the ultimate LWCO control for use with hot water or steam boilers. The LF uses Taco’s patented DualVision® technology to know the difference between foam, water, and even probe buildup. So unlike the competition, the LF won’t shut down your boiler on a false low water condition due to a dirty probe, or shutdown every 10 minutes to check for proper water level. You can now run your steam boiler flat out for a significant gain in efficiency and operational safety.
By processing and comparing two separate signals coming back through the standard probe, the DualVision® technology automatically determines the required delay on make (DOM) and delay on break (DOB) settings for any style steam boiler under any system conditions. The LF’s patented smarts means no more dip switches to set or dials to program. External LEDs and a test button verify that everything is installed and wired correctly before you leave the job. You can even wire in an alarm or electric water feeder.
