Description for Mcdonnell & Miller 153827-LWCO

The Series PSE-800 probe type LWCO uses patented technology to monitor changes in water conductivity. When defined parameters are exceeded the new PSE-800 makes a decision to shut the burner off based on the volatility/variability of the resistance readings. This new patented technology provides the best protection possible without turning off the boiler unless a low water condition exists. As an added measure of safety, the control will turn off the boiler if it recognizes an out-of-water condition when the sensitivity threshold is exceeded.

          Comments about PSE801-120, Electronic, 120V Low Water Cut-Off (Steam):

          I purchased this low water cut off last year for my gym boiler and its worked day in and day out for a year without trouble. It's still running like a top, and I decided to get another as a backup for I now trust this part, and really like the way gets the job done.
