Hydrolevel CG400-2090 Low Water Cut-Off SPDT 15Sec Delay 15 PSI 24V

The Hydrolevel CG400-2090 SPDT Low Water Cut-Off is designed for HVAC systems, especially steam boilers. It operates at 24V with a 15-second delay and is rated at 15 PSI it provides boiler safety by cutting off the burner when water levels fall below safe levels, and avoiding damage and hazardous situations. This control is typical for light commercial and residential steam HVAC system applications. Its delay time is useful in minimizing shutdowns due to momentary changes in water level. These benefits are improved boiler protection and improved system reliability.
