The McDonnell & Miller 110900 is a manual reset proportioning control switch designed for use with Series 93, 193, 94, and 194 low water cut-off pump controllers. This switch employs a single pole double break mechanism, allowing for multi-function capabilities such as alarm triggering, valve actuation, and low water cut-off operations. The control switch also manages a proportional signal that regulates a proportioning valve to maintain a constant water line.
This device enhances system safety and efficiency by providing automatic low water detection and response capabilities.
