The MCDONNELL & MILLER RB-24SE-S is an electronic low water cut-off suitable for hot water boilers. It stops the electrical current to the firing device when the water level is too low, which protects the boiler. The device automatically resets when water levels are back to normal. A test button is included to check its operation, and LED lights show power and low water status. The design of the probe helps to reduce scale build-up.
This low water cut-off helps to maintain safe boiler operation by monitoring water levels effectively.
