17. Pump running signal and fault signal
Pump running and fault signals such as lights may be wired to the AQUAVAR and set up in
remote locations such as central control rooms. The fault signal can be wired to X2 pins 1, 2
and 3 and the pump running signal to X2 pins 4, 5 and 6.
18. Analog output of pressure or frequency
A meter can be connected to X1 pins 10 and 11 for remote display of actual system pressure
or motor running frequency. The meter must be 0-10 volt with no more than 2 mA.
19. Second Sensor Input
The ground pin (X1-10) used for analog output can also be used to bridge a connection for
a second sensor. This can be digital (on/off) such as a switch which would be connected
between X
1
-10 and X
1
-14. Another choice is a sensor with a voltage signal of 0-10V or 2-10V
which would be connected to X
1
-10 and X
1
-13. A final choice is a 4-20 mA current sensor
which would be connected to pins X
1
-10 and X
1
-12.
20. Replace AQUAVAR controller ground wire to top cover and carefully reinstall top. Carefully
position the wires so that the cover sets firmly. Do not force the cover on.
21. With the cover in place, check the operation of the three buttons. You should be able to feel
the button actuate. If not, lift the cover and raise the screws (counter-clockwise) on the
button. Repeat as necessary. Replace the cover screws.
22. Connect the opposite end of the power cable to a fusible disconnect with UL Class T fuses.
Pump Priming
Refer to your pump operation manual for instructions on pump priming. You will need to unscrew
the pressure transducer and adapter if you used the pump fill plug for mounting. When priming is
complete, replace the pressure transducer. Ensure all air is out of casing and piping.

Installation Procedures
Power supplies using G.F.I. breakers will cause nuisance tripping which will result in the
AQUAVAR controller displaying an “undervoltage” fault.
