MANUAL RESET OF DRY WELL FAULT
While setting up and testing the system it is convenient to
have a quick way to clear a Dry Well fault. Pressing both
pushbuttons while the controller has this fault will clear
it and resets the restart time to 1 min. Continuing to hold
the pushbuttons down for an additional 10s will allow the
pump to come up to speed and Dry Well Power Calibration
to occur. The pump is not allowed to stop while any
pushbuttons are held down.
DRY WELL RESTART TIME
After a Dry Well fault occurs, the controller waits a period
of time to allow the well to recover. This period of time can
be chosen to be fixed at 1 minute or increasing in length
with each occurrence of the fault. The factory default is
for restart time to increase each time this fault occurs. The
controller will "forget" one of these faults for every ½ hour
of run time. This allows the restart time to automatically
shrink once a Dry Well condition is resolved. Manually
resetting the fault by pressing both pushbuttons will also
clear the restart time back to 1 minute.

SIZE OF PRESSURE VARIATION FOR FLOW
DETECTION
The controller uses pressure variation to detect when flow
has stopped. The factory default is for the pressure to vary
+/– 2 PSI. The other choices available are +/– 1 PSI and
+/– 3 PSI. Ideally one would like the smallest pressure
variation while maintaining quick turn off when flow stops.
Too small of a variation may result in the controller not
turning off and/or turning off when it shouldn't. If either
of these problems occur, increasing the pressure variation
should solve the problem. Ensuring the tank has the correct
pre-charge pressure setting and having a spring check valve
on the pump side of the tank and pressure transducer will
provide most reliable turn off performance and allow the
smallest pressure variation setting.
