McDonnell & Miller Series 752P Low Water Cut-off 752P-MT-24, Manual Reset 24V, Standard probe

The Series 751P/752P probe type LWCOs provide protection against low water conditions for commercial and industrial applications. These controls are fully CSD-1 compliant and are primarily used as LWCOs on hot water heating boilers. Features and Benefits Include:CSD-1 Code Compliance If the control is in a low water condition (water off probe) when there is an interruption of power, the control will remain in a low water condition when power is restored. The reset button will have to be pressed when the water level is restored to a level above the probe. Power Interruption If there is a loss of power, the control will automatically reset if there was water on the probe before the loss of power AND there is water on the probe when the power is restored. Self-cleaning Probe This is available only on McDonnell & Miller probe type controls which reduces probe maintenance to once every five years instead of annually. Test Button Standard on all controls to allow the control to be tested without draining the boiler or system. Green Power On & Red LEDs Standard on all units to give visual indication that the unit is powered up and when a low water condition is detected. Made in the USA.
