OPERATION
Factory Reset
The drive can be reset to factory settings if necessary. A Factory Reset will wipe out all of the saved
user settings that have been programmed, except for the time of day. Be sure that it is necessary
before performing a Factory Reset, as the results are immediate.
To perform a Factory Reset:
1. Stop the pump if necessary by pressing the Start/Stop button.
2. Record all of the custom schedule settings using Table 3. You can find these setting by pressing
the "1", "2", "3", and "Quick Clean" buttons and cycling through all the screens. Also write down the
Priming Speed.
3. Press and hold the "1", "2", "3", and "Quick Clean" buttons for 3 seconds.
4. The screen will display "FACt rSt" if factory reset is successful. See Figure 9.
5. Be sure to reprogram the schedule and priming speed after the factory reset. The pump must
be turned back on with the Start/Stop button before it will run again. The pump will run the
programmed schedule upon initial start-up.
Note: Factory Reset can not be performed from a Keypad Lockout state.

Control with External Control and Digital Inputs
The user can run the WhisperFlo VS 1500 Variable Speed Pump with automation external
controls, allowing all four programmed Speeds to be controlled remotely. The pump has
a sealed connector that can be used with Pentair External Control Wiring Kit (Pentair P/N
353129Z) to run the Speeds using digital input signals. When there is an external low voltage
signal present on the Speed Digital Input line, the pump will run the speed programmed
for that Digital Input. The supplied +5V signal is the recommended input used for external
control and Speed Digital Inputs.
Connecting to External Controls
Using the Supplied Low Voltage Signal for Digital Control
The WhisperFlo VS 1500 provides a low voltage output signal that can be used to trigger its
own Digital Inputs. This signal will need to be switched via the External Control system to
engage the speed that it is connected to as in Figure 10. This could be an automation relay
or switch in another piece of equipment. This feature could be useful for ensuring that the
pump is running a certain program when a specific speed is needed to perform a task. The
wire included with the External Control Wiring Kit (Pentair P/N 353129Z) will need to be cut
to length for the installation. Do not leave excess wire around the installation, and the wire
should be supported by something rigid if conduit is not used. At one end of the cable is a
custom moulded, watertight connection that plugs into the panel connection on the side of
the drive. The opposite end has 6 wires that are defined by Table 1 below. When using the
+5V signal supplied by the drive, the speeds should be wired as shown in Figure 10. When
there is a low voltage signal present on the Speed Digital Input line the pump will run the
speed that is programmed for the speed that is being triggered. The +5V signal supplied via
the (red) wire is the suggested input for the Speed Digital Inputs. See Figure 10.
Note: Any relay can be associated to any Digital Input. Figure 10 shows one of many potential
wiring options available to the installer, allowing you to install External Controls in the way
that best suits your needs.
Note: This +5V Signal (red wire) is output from the drive only, and should never be wired to
another power supply!
When a Speed Digital Input is triggered, the LED above the Speed button will begin to
blink and the display will toggle between the display parameter and "EC" indicating an
External Control is running. The pump will run this speed as long as the Digital Input trigger
is present. This will override the schedule or any user inputs for Speed selections via the
keypad. The Display button is still functional along with the Start/Stop button. Once the
Digital Input trigger is removed from all of the Speed Digital Input wires, the pump will
resume the programmed schedule.
