3.2.4 Installing the Controller
The VS-FHP pump can be operated by one (1)
of three (3) controllers: the variable-speed controller,
the AquaLink
®
RS controller (Rev O or later), or the
AquaLink PDA (Rev 4.0 or later). The FloPro variable-
speed pump communicates with the controllers via a
four-wire RS-485 interface.
The VS-FHP pump comes equipped with a factory
installed four-wire RS-485 cable. This RS-485 cable
comes with an additional shielded wire for grounding.
The shielded wire is to be grounded ONLY at
one end, at the VS-FHP pump. This is pre-installed at
the factory. At the other end, the shielded wire is pre-
trimmed at the factory.
If you need to cut the RS-485 cable to any custom
length, make sure to peel back and trim the ground
shielded wire.
To install the variable-speed controller:
IMPORTANT
The installer must TURN ON switches 1 and 2 at the
VS-FHP pump when connected to the variable-speed
controller.
NOTE
The variable-speed controller part no. is JEP-R.
1. Remove power from the VS-FHP pump by
disconnecting the high voltage lines or by opening
any breaker to which the VS-FHP pump power is
connected.
wARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in the
VS-FHP pump electrical circuit before starting the
procedure. Failure to comply may cause a shock
hazard, resulting in severe personal injury or death.
2
. Slide dip switches 1 and 2 up, so they are in the
ON position, and slide switches 3 and 4 down, so
they are in the OFF position. See Figure 4.

3. Connect the other end of the cable to the
controller. Match the colors of the wires with the
appropriate connector positions as follows: 1- red,
2- black, 3- yellow, and 4- green.
4. Restore power to the VS-FHP pump and verify the
operation of the controller.
5. Refer to the Variable-Speed Controller Owner’s
Manual, H0311200, to operate the pump.
