Time of Day
Press the SET button. The display will show the Time of Day with the minutes digit blinking. If you want to change this number, press the UP ARROW (↑) button to increase the number or the DOWN ARROW (↓) button to decrease the number. To skip the number without changing, press the LEFT ARROW (←) button. The first number stops flashing and the next number starts flashing. You can only change the flashing number. When you have reached the far left digit, pressing the LEFT ARROW (←) button returns you to the far right digit. Continue changing numbers until you reach the desired setting. Press the SET button again to save the value.
Time of Regeneration
The next value displayed is the Time of Regeneration. It is similar to Time of Day programming. It has a default value of 2:00 a.m. If 2:00 a.m. is acceptable, press the DOWN ARROW (↓) button. If this is not acceptable, press the SET button and change the numbers. Press the SET button again to save the value.
Factor A
Factor A is the next value displayed. Factor A is the potassium permanganate demand of the water being treated. Determine the potassium permanganate demand of the water supply and enter that value for Factor A. The formula below can be used to calculate potassium permanganate demand from a water analysis.
From water analysis: |
|
Iron content (Fe2) = | ________ppm |
Manganese content (MN2+) x 2= | ________ppm |
H2S content x 4= | ________ppm |
Total Demand= | ________ppm |
Example: |
|
4.0 ppm iron = | 4.0 ppm |
3.0 ppm Manganese x 2 = | 6.0 ppm |
2.5 ppm H2S x 4 = | 10.0 ppm |
Potassium Perm. Demand = | 20.0 ppm |
Regenerant Dosage
Regenerant dosage is the next value displayed. Refer to Table 6 to find the correct regenerant dosage setting based on the volume of filter media and the average room temperature of the installation site. Enter the correct value from Table 6.
Capacity
Capacity is the next value displayed. Refer toTable 7 to find the correct system capacity setting based on filter media volume. Enter the capacity setting from Table 7.
Note: The Performa 960 FA control uses the Capacity and Factor A settings to calculate the system capacity in gallons (cubic meters). If the calculated system capacity exceeds 9999 gallons (99.99 cubic meters), the control will display 9999 (99.99 cubic meters), for capacity until the water usage has dropped the remaining capacity below that number. When water is flowing through the system, the colon in the Time of Day display will blink.
At this time, all of the Level I Parameters are programmed. The display will alternate between the Time of Day and Capacity if no keys are pressed for 30 seconds. The Capacity value displayed is the volume remaining in gallons (cubic meters for metric) before a regeneration is needed.
To complete the initial programming of the Performa 960 FA proceed to the Level II Parameters, page 15.
