AQUASENSOR:
Troubleshooting statistics.
z-Ratio (impedance ratio)
- Number calculated by microprocessor on measured voltage
values that are converted to a digital representation. This is the value that the control
monitors in order to determine need for regeneration and salt rinse-out.
z-Minimum (minimum impedance ratio)
- Reference point that the Z-ratio is
compared to, in order to initiate a regeneration. This number is reset after every successful
regeneration.
Increase Percent (impedance ratio increase)
- During service, this number
represents the percent increase or z-ratio over z-minimum. A regeneration is initiated when
it reaches 7.5% or more for at least 6 minutes.

SBT SENSOR:
Smart Brine Tank Probe troubleshooting statistics.
The SBT probe has four sensors within it. The Check sensor screen displays the current status
(opened = “OP”, or blocked =“BL”) for all four sensors. The expected outputs from the SBT probe
inside the brine tank are shown in Table 1 below while the expected outputs from an SBT probe
“in air” are shown in the Table 2.
Table 1 - Expected Readings on the Sensor/Diagnostic screen when the SBT probe is installed inside the brine tank
displays “BL”
displays “OP”
Salometer
Brine at least 1 inch above the salt plate.
Salt Level
Normal Operation .– Salt level greater than 8”
above the salt plate
Salt level less than 8” above the salt plate
Flow Rate #1
Water level in brine tank is below salt plate
Water level is brine tank is more than 1”
above salt plate
Flow Rate #2
Water level is brine tank is more than 1” above
salt plate
Water level in brine tank is below salt plate
