(either A or B) can be in use at any time.
Water Quality “GOOD” Status Indicators
The green “GOOD” status LED light indicators are ON when their
respective Bank’s water quality is acceptable or ABOVE
Controller Set Point - Resistivity (the reverse is true for
Conductivity - BELOW).
Water Quality “POOR” Status Indicators
The red “POOR” status LED light indicators are ON only when
their respective Bank’s water quality is unacceptable or BELOW
Controller Set Point - Resistivity (the reverse is true for
Conductivity - ABOVE).
“BLEED” Indicator Light
The amber “BLEED” LED indicator light is ON only when the
AQUASWITCH is in its Purge Cycle (Bleed/Process Water
valve(s) are activated).
“BANK SWITCH” Push Button

The green LED indicator light is ON only when the resistance of
the water is ABOVE the Controller’s internal Set Point.
The red LED indicator light is ON only when the resistance of the
water is BELOW the Controller’s internal Set Point.
NOTE: The reverse is true for Conductivity.
“SET POINT CHECK” Switch
When the “SET POINT CHECK” switch is pressed, the internal Set
