AQUAPUMP VARIABLE SPEED CIRCULATING PUMPS
WARNING
The electrical supply must be disconnected when
wiring the circulator.
4.2 ANALOG INPUT (OPTIONAL)
WARNING
Ensure circulator is disconnected. Wire must remain
isolated from power.
Wire shall be 18 to 24 gauge solid wire or stranded wire.
To connect, loosen the screw from the wiring box cover and
remove the screw and cover.
Install some form of strain relief connector (included in the
box) on the left side of the wiring compartment and tighten
enough so the wire does not slide when pulled.
Insert wires through the connector(s).
Strip 3/16" of insulation from the ends of the two wires to be
connected.
To insert the wires into the analog input terminal strip, press
the terminal lever forward firmly. Insert the stripped wire into
the opening and release the lever (see Fig. 3). Tug on the wire
gently to ensure it is secured.
Connect the positive wire to terminal "v" for voltage input
control and the neutral wire to terminal "c" (see Fig. 5).

Analog Input Setting
The pump can be controlled by an external controller via 0-10
VDC. (See Fig. 5 for how to install analog input wiring) Ensure
the analog input mode is selected.
The pump will vary the performance as per the external
analog signal. See Fig. 6.

At an input voltage lower than 2V, the pump will be off. The
pump will start to operate at the min. curve at or above 2V.
The pump will reach max. curve at 10V. See Fig. 7.
