PSI. After the pressure has stabilized, use the Increase/
Decrease Pressure Adjust Pushbuttons on the right-hand
side of the controller to adjust the pressure setting.
Push and Hold the Increase or Decrease Pressure
Adjust Pushbutton until the desired pressure setting is
reached. The new pressure setting is automatically saved.
Close the faucet and turn power to controller off. Wait 5
minutes before installing the controller access cover.
NOTE: The maximum allowable pressure setting is
85 psi.

Setting Switches while the power is on.
The controller has 6 possible Application Settings.
These settings are used to adjust the Minimum Speed
of the motor and the Ramp Setting, or acceleration and
deceleration ramp. This allows the controller to fit a wide
range of applications.
Before adjusting the Application Switches, turn the
circuit breaker and disconnect switch to the off position.
Wait 5 minutes. Remove the controller access cover. On
the inside of the access cover is the Application Switch
Setting Table. See Diagram 6 for details. This table
shows the switch setting needed for the desired system
response. See Diagram 3 for details.
Select a Minimum Speed of 10 Hz if the pressure at the
pump's suction is within 20 PSI of the desired pressure
setting. Select a Minimum Speed of 30Hz if the pressure
at the pump's suction is more than 20 PSI below the
desired pressure setting, if pumping from a tank or if
drawing a suction lift.
Changing the Ramp Setting changes how fast the
controller can change the speed of the motor. A Slow
Ramp Setting allows the controller to work better in
applications where the average demand for water is low
(less than 3GPM or about 1 faucet). A Fast Ramp Setting
allows the controller to work better in applications where
the demand for water is high because the motor is
allowed to change speed faster.
NOTE: The Application Switches are preset at the
factory to "0000" or Minimum Speed = 30 Hz, Ramp
Setting = Fast.
Motor Rotation Direction
If the pressure or flow seems low, check motor rotation
direction. Turn the circuit breaker and disconnect switch
to the off position, and wait 5 minutes. Switch any two
leads on the controller output (T1, T2, or T3). Turn the
circuit breaker and disconnect switch to the on position.
Observe pressure and flow. If pressure or flow still
seems low check plumbing.
NOTE: It is possible for the pump to maintain constant
pressure with a low flow or a high positive suction
head even if the pump is rotating backwards. While
the pump is running, use an amp probe on one of
the output power leads connected to the motor and
compare the current draw between the two rotation
directions. The lowest current reading indicates the
pump is running in the correct direction.
System Status
The controller is always powered. A Solid Green Status
Code indicates that the pump is in standby mode (pump
not running) or that the line input voltage is low.

and circuit breaker and wait 5 minutes
before servicing.
A Blinking Green Status Code indicates that the pump
is running. A Blinking or Solid Red Light indicates a
problem with the controller. Refer to the access cover
side panel or Diagram 6 for Status Codes. See Section 9
for more details.
