Abstract

Motor speed, motor amps, float position and elapsed run time are monitored to determine whether a sump pump is in a normal condition, a jammed condition, an inadequate pumping rate condition, a dry running condition or a stuck float condition. A processor is configured to increase the motor speed in response to an inadequate pumping rate condition, and to rapidly energize the motor clockwise and counterclockwise in response to a jammed condition or a stuck float condition. The processor provides signals to a display for displaying information about the condition that the pump is in. The pump is set up to receive power from either an AC power source or a battery power source. Availability of the AC power source is monitored and the pump is switched to operate from the battery power source when AC power is unavailable.
