5. Unit Capacity (Display Code C)
Press the Extra Cycle button. Use this display to set the Unit
Capacity. This setting specifies the treatment capacity of the
system media. Enter the capacity of the media bed in grains of
hardness when configuring a softener system, or desired volume
capacity when configuring a filter system. This option setting is
identified by “C” in the upper left corner of the screen (or by “V” if
volume capacity for a filter). 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: 1-999.9 x 1000 grains/gallon (mg/liter)
6. Feed Water Hardness (Display Code H)
Press the Extra Cycle button. Use this display to set the Feed
Water Hardness. Enter the feed water hardness in grains per
gallon or degrees for softener systems. This option setting is
identified by “H” in the upper left corner of the screen. The feed
water hardness parameter is only available if the control type has
been set to one of the metered softener options. Use the Up and
Down buttons to adjust the value as needed.

Range: 1-199 grains (degrees)
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 sys-
tem. This setting is identified by “RS” in the upper left 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 three possible settings.

8. Safety Factor (Display Code SF)
Press the Extra Cycle button. Use this display to set the Safety
Factor. This setting specifies 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 feed water
hardness that changes the calculated system capacity will result
in a corresponding change to the reserve volume. This option
setting is identified by “SF” in the upper left corner of the screen.
Use the UP and Down buttons to adjust the value from 0 to 50%
as needed.

Range: 0-50%
9. Fixed Reserve Capacity (Display Code RC)
Press the Extra Cycle button. Use this display to set the Reserve
Capacity. This setting specifies a fixed 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 fixed volume and does not change if the unit
capacity or feed water hardness are changed. This option setting
is identified by “RC” in the upper left corner of the screen. Use
the Up and Down buttons to adjust the value as needed.
