Description

Hydrolevel Safgard 500 is a 24V commercial-grade low water cut-off (LWCO) for hot water gas boilers w/ manual reset and test button. Immediately interrupts power in a low water condition, locks out burner circuit if water remains below probe level for longer than 30 seconds. Manual reset will not trip due to power failures. Test button simulates low water condition and allows for checking control without lowering the water level in a system.
