12. At the pump, press Display to advance.
Note: If the pump displays “LoFlo” or “HiFlo” and
a percentage other than “100” (see Figure 20),
adjust 20-set setting at the owmeter until the
pump displays “100”.
13. “Aver” will display (see Figure 21). Use “+” and “-”
to match the owmeter’s averaging value.
14. Press Display. “Auto Tuning” will scroll across
the screen as the pump auto tunes. The motor
will drop to half speed and then slowly ramp down
until the minimum controllable ow is found.
Note: Auto Tuning process will take several
minutes to complete, or much longer in
installations with longer plumbing systems.

Adjusting Flow Setting
1. Use “+” and “-” to increase or decrease the Flow
Percentage. This percentage is based on the
high speed set during Flow Mode setup and
conguration.
Example: If ow mode maximum speed is
3000 RPM, lowering ow percentage to “50”
will decrease the motor RPMs until the pump is
producing 50% of the ow created at 3000 RPM.
