SET LOW SALT ALERT: Press (  ) or (  ) to change Alert Level from 0 to 4. This num-
ber corresponds with the numbers on the brinewell. When the salt level falls below
this level the controller will signal that salt needs to be added to the brine tank. Press
the Menu/Exit ( ) button to select and return to the Advanced/Service menu. Note:
Not available for if System Type (step 5) is set to Filter.
SET MAX DAYS/RECHARGE: Press (  ) or (  ) to change Max Days Between Re-
charges. If Automatic is selected, the algorithm will determine when to recharge. If
1 to 15 is selected, the unit will never go past the number of days set for a recharge,
but could recharge before. Press the Menu/Exit ( ) button to select and return to the
Advanced/Service menu.
SET 97% FEATURE: Press (  ) or (  ) to set either OFF or On. If ON is selected, the
unit will automatically recharge when 97% capacity has been used, at any time of the
day. Press the Menu/Exit ( ) button to select and return to the Advanced/Service
menu. Note: This feature is available for single tank or Parallel Delayed configurations
only.
SET CHLORINE/BYPASS: This feature is for European units. Press (  ) or (  ) to
set on Bypass, Chlorine---Half Wave or Chlorine---Full Wave. Press the Menu/Exit (
) button to select and return to the Advanced/Service menu.
VALVE CONFIGURATION: This option allows you to reprogram the controller. After
all valve configuation selections have been made, all other settings (clock, water hard-
ness, etc.) will need to be reset. Note: The controller will also reset all counts back
to zero (number of recharges, etc.), except for the number of days in service.
ELECTRONIC CONTROLLER AND WATER METER
The controller is actually a small computer. As it receives
pulses from the water meter it converts them to gallons
of water passing through the unit. It multiplies this water
usage information times the water hardness (prepro-
grammed into timer) to continually calculate the condi-
tioned water capacity required. The computer adjusts
daily to water using habits, seeking to supply condi-
tioned water for the longest time, using the least (and
most efficient) amount of salt and water to regenerate.
When the computer determines more capacity is need-
ed, at the next regeneration starting time (2:00 a.m., or
as otherwise preset), it will schedule a regeneration. RE-
CHARGE TONIGHT shows in the display to inform of the
coming regeneration.
The water meter is located in the 1" valve outlet on single
units only. It consists of a turbine, turbine mounting as-
sembly, and a sensor housing pickup (Figure 9). The tur-
bine and sensor pickup are oriented in–line, centered in the water stream. Water flow turns the turbine, which
houses two small magnets. As the turbine spins, the magnets cause the sensor pickup to switch back and
forth. This switching sends an electrical pulse through the sensor leads, to the circuit board computer. The
computer counts the pulses and converts them to gallons. The sensor is in a sealed chamber to keep out dirt,
moisture and corrosion.
