Performa 960 FA Level II Parameters
The Level II Parameters are P6 through P19 in Table 8.
The Operating and Maintenance Manual for this product
does not mention these parameters, so the end user does
not normally have access to these values. To access Level
II Parameters, simultaneously press and hold the
DOWN
ARROW
(
↓
) and
UP ARROW
(
↑
) button for three seconds.
If the control was alternating between Time of Day and
Capacity when the above button sequence is entered, the
display shows P1. If a different Level I Parameter was
displayed, the display snows the “P” number for that
parameter. Refer to Table 8 to find the “P” number
associated with each parameter.
Use the
UP ARROW
(
↑
) button or the
DOWN ARROW
(
↓
)
button to move from one parameter to the next. The
display cycles through the “P” numbers shown in Table 5
and Table 8 When you reach P19, the display will go back
to P1.
When the parameter number you want to change is
displayed, press the
LEFT ARROW
(
←
) button to display
the data assigned to that parameter. Press the
SET
button
and the far right digit on the display starts flashing. If you
want to change this number, press the
UP ARROW
(
↑
)
button or the
DOWN ARROW
(
↓
) button. To skip the
number without changing, press the left arrow button.
When the number is correct, press the
SET
button. The
numbers stop flashing and the control accepts the new
setting. If the new setting was not accepted, the display
will show the previous setting. Refer to Table 8 for
allowable values for that parameter.
To change or view other parameters, press the
LEFT
ARROW
(
←
) button to have the display show “P” numbers.
Now use the
UP ARROW
(
↑
) button or the
DOWN ARROW
(
↓
) button to move to the parameter number you wish to
change.
To exit the Level II programming mode, simultaneously
press and hold the
DOWN ARROW
(
↓
) and
UP ARROW
(
↑
)
buttons for three seconds, or wait 30 seconds without
pressing a button. The control starts alternating the
display between Time of Day and Capacity.
Refill Controller
•
Parameter P6 is used by the Performa 960 FA control
to calculate the refill dwell time and provide accurate
regenerant refill volumes. Refill controller must be set
to 46 for proper system operation. The default value in
P6 is 33. Press the set button and enter 46.
Regenerant Draw Value
•
Parameter P7 is used by the control to calculate the
regenerant draw time. The default value of 25 was
selected for a “B” injector with low water pressure or
an “A” injector with moderate water pressure. If this
does not match your installation, press the
SET
button
and enter a new value. Refer to Table 9 for the correct
value. The injector cap is labeled with the injector
letter. The injector is color coded for easy
identification. Next, determine the typical water
pressure for this installation. The Regenerant Draw
value is an estimate of the flow rate of regenerant
through the injector. This rate varies with water
pressure and injector type as shown in Table 9. The
control calculates the regenerant draw time using this
value and the Regenerant Dosage. The regenerant
draw time is added to the Slow Rinse Time (P10) to
determine the total Regenerant Draw/Slow Rinse
Time.
•
This control does not use parameter P8. No entry is
needed for this parameter.
•
Parameter P9 is used to set the backwash time in
minutes. The default in P9 is 14 minutes. If a different
backwash time is desired, press the
SET
button and
enter a new value.
Slow Rinse Time
•
Parameter P10 determines the slow rinse time. The
default value for P10 is 40 minutes. If a different slow
rinse time is desired, press the
SET
button and enter a
new value.
•
Parameter P11 determines the fast rinse time. The
default value is 4 minutes. If a different fast rinse time
is desired, press the
SET
button and enter a new value.
•
Parameter P12 selects the units of measure. Be sure
that this is set to the correct value before entering any
data for parameters P3, P4, or P5.
•
Parameter P13 selects the clock display mode. If the
12 hour mode is selected, a PM indicator is used. If the
24 hour mode is selected, the PM indicator is not used.
•
Parameter P14 is used to set the calendar override
feature. The default value is zero. If set to zero, the
feature is disabled. Refer to
Calendar Override
, on
page 17 for more information on the calendar
override feature.
•
Parameter P15 selects a variable reserve type, 0 to 13.
For more information see Reserve Options below.
•
Parameter P16 is used to calculate the initial average
daily water usage values. The control multiplies the
