The Low Water Cutoff (LTA-2) is a microprocessor based low water cutoff for detecting the presence to water in a boiler. The LTA-2 uses advanced signal processing to identify when the probe signal levels have decreased due to possible fouling. These advanced technologies permit extended operation for probe impedance up to 40K Ohms. The LTA-2 functions longer without requiring probe cleaning, and it functions normally under non-ideal installation conditions. The LTA-2 is designed for use with hot water boilers and hot water heating boilers. (See each boiler manufacturers' specifications for recommended minimum safe water levels.) During a low water condition, the Status LED will illuminate RED. Under normal conditions, it will illuminate GREEN. See Status LED States table for details.
