Description
From Plumbing Deals' product listing.
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. Features Green power is on indicating LED Red low water indicating LED 30 second DOM Test button Self-Cleaning probe No lock out with loss of power if probe is in water Provisions to add water feeder of alarm Models available with: 120 VAC 24 VAC (meets ANSIZ21.13a specification) ‘U’ probe (extended barrel) “FIX2′ probe (remote)
