Taco LFM0243R-1 Electronic, (24V) Man. Reset 3/4" NPT Low Water Cut-Off, Remote Probe w/ NEMA 4 Enc. (Water)

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 shut down 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.
