4. Control Type (Display Code CT)
Press the Extra Cycle button. Use this display to set the Control
Type. This specifies how the control determines when to trigger
a regeneration. For details on how the various options function,
refer to the Control Operation section of this service manual.
This option setting is identified by "CT" in the upper left hand
corner of the screen. There are four possible settings.

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 hand 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 hand 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.

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

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 hand 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-hand
corner of the screen. Use the Up and Down buttons to adjust
the value as needed.
