Description

Hydrolevel CycleGard 400-2090 is a 24V low water cut-off w/ auto reset and intermittent level test (ILT), designed for use as a primary LWCO control on steam boilers (mostly gas-fired). Burner circuit contacts open after 15 second delay in a low water condition. Delay prevents short cycling caused by momentary fluctuations in the boiler water level. Automatically restarts burner circuit 30 seconds after water reaches the probe, allowing optional water feeder to raise water level above the probe. ILT removes power from the burner circuit and monitors settled (true) water level every 20 minutes (interval) for 90 seconds (duration) for added protection.
