Smart Reset
If a motor underload fault condition occurs, the most likely
cause is an overpumped or dry well. To allow the well to
recover, the CP WATER SD100 will wait 30 seconds to 5
minutes, determined by duration of the previous run time,
before restarting the motor. For example the first time the
fault occurs, the CP WATER SD100 will wait 30 seconds
before attempting to restart the pump. If the system would
then run for 1 minute and an underload fault reoccurs, the
controller will wait 4 minutes before attempting to restart
the pump. This schedule allows for the minimum off-time
possible based on the recovery time of the well.

TROUBLESHOOTING GUIDE
Symptom
Possible Cause
Corrective Action
Water flow rate is not as high
as expected
Excessive pressure
fluctuations
Motor runs continuously with
no flow demand from the
house.
Motor is running backwards.
Temperature in the controller is
too high. If the controller’s heat
exchanger becomes too hot, the
controller will reduce the speed
of the pump to lower the power
consumption.
Pump capacity cannot supply the
demand
Waterlogged tank.
Pressure tank is too small for flow
rating of the pump.
Leak in the pitless adapter.
Leak in the household or outdoor
plumbing.
Switch two of the three wires leading from the
controller to the motor (3-phase motor).
Make sure there is at least 6 inches of room
around the controller for movement of air.
Use pump with higher flow rating (if head
requirement is still satisfied).
Check tank for bladder damage - replace if
necessary.
Reset the tank pre-charge pressure (should be
70% of pressure sensor setting).
Use larger tank (4 gal tank minumum).
Re-seat the pitless adapter
Check for leaky faucets, valves and pipe fittings
and repair.
