5. Unit Capacity (Display Code C)
Press the Extra Cycle button. Use this display to set the Unit
Capacity. This setting species the treatment capacity of the
system media. Enter the capacity of the media bed in grains
of hardness when conguring a softener system, or desired
volume capacity when conguring a lter system. This option
setting is identied by "C" in the upper left hand corner of
the screen (or by "V' if volume capacity for a lter). The Unit
Capacity parameter is only available if the control type has
been set to one of the metered options. Use the Up and Down
buttons to adjust the value as needed.

Range: 1-9,999,000 grains/gallon (1-9,999,000 mg)
6. Feedwater Hardness (Display Code H)
Press the Extra Cycle button. Use this display to set the
Feedwater Hardness. Enter the feedwater hardness in grains
per unit volume for softener systems, or 1 for lter systems.
This option setting is identied by "H" in the upper left hand
corner of the screen. The feedwater hardness parameter is
only available if the control type has been set to one of the
metered options. Use the Up and Down buttons to adjust the
value as needed.

Range: 1-199 grains (mg/l)
7. Reserve Selection (Display Code RS)
Press the Extra Cycle button. Use this display to set the Safety
Factor and to select the type of reserve to be used in your
system. This setting is identied by "RS" in the upper left-hand
corner of the screen. The reserve selection parameter is only
available if the control type has been set to one of the metered
options. There are two possible settings.

8. Safety Factor (Display Code SF)
Press the Extra Cycle button. Use this display to set the
Safety Factor. This setting species what percentage of the
system capacity will be held as a reserve. Since this value is
expressed as a percentage, any change to the unit capacity
or feedwater hardness that changes the calculated system
capacity will result in a corresponding change to the reserve
volume. This option setting is identied by "SF" in the upper left
hand corner of the screen. Use the UP and Down buttons to
adjust the value from 0 to 50% as needed.
Figure 20
Range: 0-50%
9. Fixed Reserve Capacity (Dispaly Code RC)
Press the Extra Cycle button. Use this display to set the
Reserve Capacity. This setting species a xed volume that will
be held as a reserve. The reserve capacity cannot be set to a
value greater than one-half of the calculated system capacity.
The reserve capacity is a xed volume and does not change
if the unit capacity or feedwater hardness are changed. This
option setting is identied by "RC" in the upper left-hand corner
of the screen. Use the Up and Down buttons to adjust the
value as needed.

Range: 0-half of the calculated
10. Day Override (Display Code DO)
Press the Extra Cycle button. Use this display to set the Day
Override. This setting species the maximum number of days
between regeneration cycles. If the system is set to a timer-
type control, the day override setting determines how often
the system will regenerate. A metered system will regenerate
regardless of usage if the days since last regeneration cycle
equal the day override setting. Setting the day override value
to "OFF" disables this function. This option setting is identied
by "DO" in the upper left hand corner of the screen. Use the Up
and Down buttons to adjust the value as needed.
