Ensure power is isolated before
conducting test
Mark and disconnect switch wiring and
using a multimeter on the x1 resistance
scale, measure across switch terminals.
The readings should be as follows.
On Spa: Term A - 1 (red wire) less than 1 ohm
Term A - 2 (black wire) infinity ohms
Term A - 3 (blue wire) infinity ohms
On Remote: Term A - 1 (red wire) infinity ohms
Term A - 2 (black wire) less than 1 ohm
Term A - 3 (blue wire) infinity ohms
On Pool: Term A - 1 (red wire) infinity ohms
Term A - 2 (black wire) infinity ohms
Term A - 3 (blue wire) less than 1 ohm
Ensure power is isolated before
conducting test
Disconnect water sensor at cable joiners.
Using a multimeter on the resistance scale,
measure across the two sensor leads.
Normal reading should be approximately 10
kilo ohms @ 25º C. For other temperatures
refer to the “Water Sensor V’s Temperature
Chart” on page 42.

Ensure power is isolated before
conducting test
Switch selector switch to “Remote”. Using
a multimeter on the resistance scale,
measure across the red and black wires
on the Spa potentiometer whilst rotating
throughout its range. The resistance value
should change smoothly from 0 – 10 kilo
ohms (approx).
Ensure power is isolated before
conducting test
Switch selector switch to “Remote”. Using a
multimeter on the resistance scale, measure
across the blue and black wires on the Spa
potentiometer whilst rotating throughout its
range. The resistance value should change
smoothly from 0 – 10 kilo ohms (approx).
