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
IIParameters, 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
