Run Time Adjustment
This product defaults to a 10 second run duration and can be reprogrammed at anytime by following these steps.#
How the Sensor Works: Do I need a ground wire?
The sensor detects the presence of water by using a continuity circuit. The continuity circuit works by allowing a
small current to flow from the sensor, through the water, to the ground when the tip of the sensor is in water. When no
water is present, the circuit is broken and no current flows. Normally, the pump provides the ground reference need-
ed for the continuity circuit to work, but occasionally it won’t. When this happens, it is necessary to provide a ground
reference for the sensor to work.#
Adding a Ground Wire:
Alarm & LED Guide
Silence or eliminate all active alarms: There should be no audible alarms active (See “Smart Button
Features” on how to disable alarm).
Press and hold the Smart Button for approximately 5 seconds, or until the output turns on and the light
starts to flash green. The output turning on marks the start of the desired run time duration
NOTE: If the pump is in the middle of a run cycle when the Smart Button is pressed and held, the output
will turn off for a moment (canceling the cycle) then restart to mark the start of the run time programming.
Release the Smart Button when the desired run time is reached. The output will turn off and the switch is
now reprogrammed with the new run time duration.
NOTE: Loss of power does not affect the programmed run time.
Strip 1 inch of insulation off each end of a 14 AWG
length of wire.
Secure one end of the wire to a metal water pipe or oth-
er metal electrical conduit.
Place the other end of the wire into the pit so that it is
below the bottom sensor.#
NOTE: No danger of electrocution. Visit our website

The switch’s output is on (the pump
is on).
The switch’s output is off (the pump
is off).
The switch did not detect a motor
current during the previous pumping
cycle.
