tank one or tank two is in service. This option setting is
identified by “TS” in the upper left hand corner of the screen.
This parameter is only available if the number of tanks has
been set to 2. There are two possible settings:
Tank One in Service: U1
Tank Two in Service: U2
6. 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, and in the
desired volume capacity when configuring a filter system. This
option setting is identified by “C” in the upper left hand corner
of the screen. 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: 1-999,900 gallons (100-9,999,000 Liters)
7. 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 filter systems.
This option setting is identified 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.

9. 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 feedwater 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%
10. 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 feedwater 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.
Range: 0-half the calculated capacity
11. Day Override (Display Code DO)
Press the Extra Cycle button. Use this display to set the Day
Override. This setting specifies 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 identified
by “DO” in the upper left hand corner of the screen. Use the Up
and Down buttons to adjust the value as needed.
Range: Off-99 days
