Programming Switches
The circuit board will require the proper setting of the dip switches in order to function properly. Figure 1 shows the dip switches.
Switch 1 - Sets the unit in the Run or Test mode.
Switch 2 - Sets the unit for Filter or Softener.
Switch 3 - Sets the flow meter K factor for the 3/4" or 1-1/4" flow meter.
Switch 4 - Sets the control for 9" or 12" diameter tanks.
Switch 5 - Sets the unit for the standard or accelerated Refill cycle.
NOTICE: For an accelerated Refill cycle, the refill flow control in the brine refill assembly must be changed to PN 00-4016-23.
Switch 6 - Sets the unit for immediate or delayed regeneration.
Switch 7 - Sets the unit to measure in liters and French or German hardness, or in gallons and the conventional gpg hardness.
Switch 8 - Sets the unit to display time with a 24 or 12 hour clock.
Switch 9 - Sets the unit for either French or German hardness degrees when switch #7 is in the ON position.
Switch 10 - When turned ON, the microprocessor will force a regeneration based on the setting 8A in the menu.

Auxiliary Connections
Refer to Figure 2 for all circuit board connections.
Power terminals are located along the lower section
of the circuit board. The connection marked 'POWER'
is for the transformer connector, and the motor con-
nection is marked 'MOTOR'. The connection for the
cam switch harness, marked 'CAM', is located in the
upper right corner near the dip switches. The Aqua-
Sensor sensing device connection is located in the
lower center of the board, just above the power con-
nectors, while the Soft-Minder connection is located
in the upper left side of the board. Just below the
meter connection is a connection marked 'BATT',
which is for the optional battery back-up. All termi-
nals are clearly marked to ease installation.
