Location Selection  
1. The distance between the unit and a drain should be as  
short as possible.  
2. If it is likely that supplementary water treatment  
equipment will be required, make certain adequate  
additional space is available.

3. Since salt must be added periodically to the  
regenerant tank, the location should be easily  
accessible.

4. Do not install any unit closer to a water heater than a  
total run of 10 feet (3 m) of piping between the outlet  
of the conditioner and the inlet to the heater. Water  
heaters can sometimes overheat to the extent they  
will transmit heat back along the cold pipe into the  
unit control valve.

Hot water can severely damage the conditioner. A  
10-foot (3-m) total pipe run, including bends, elbows,  
etc., is a reasonable distance to help prevent this  
possibility. A positive way to prevent hot water  
flowing from heat source to the conditioner, in the  
event of a reverse flow situation, is to install a check  
valve in the soft water piping from the conditioner. If a  
check valve is installed, make certain the water  
heating unit is equipped with a properly rated  
temperature and pressure safety relief valve. Also,  
be certain that local codes are not violated.

Drain Line Connection  
Note: Standard commercial practices are expressed here.  
Local codes may require changes to the following  
suggestions.  
5. Do not locate unit where it or its connections  
(including the drain and overflow lines) will ever be  
o
o
subjected to room temperatures under 34 F (1 C) or  
1. Ideally located, the unit will be above and not more  
than 20 feet (6.1 m) from the drain. For such  
installations, using an appropriate adapter fitting,  
connect 1/2-inch (1.3-cm) plastic tubing to the drain  
line connection of the control valve.  
o
o
over 120 F (49 C).  
6. Do not install unit near acid or acid fumes.  
7. The use of resin cleaners in an unvented area is not  
recommended.  
2. If the backwash flow rate exceeds 5 gpm (22.7 Lpm) or  
if the unit is located more than 20 feet (6.1 m) from  
drain, use 3/4-inch (1.9-cm) tubing for runs up to 40  
feet (12.2 m). Also, purchase appropriate fitting to  
connect the 3/4-inch tubing to the 3/4-inch NPT drain  
connection.  
Water Line Connection  
The installation of a bypass valve system is recommended  
to provide for occasions when the water conditioner must  
be bypassed for hard water or for servicing.  
The most common bypass systems are the Autotrol Series  
1265 bypass valve (Figure 1) and plumbed-in globe valves  
(Figure 2). Though both are similar in function, the Autotrol  
Series 1265 bypass offers simplicity and ease of operation.  
3. If the unit is located where the drain line must be  
elevated, you may elevate the line up to 6 feet (1.8 m)  
providing the run does not exceed 15 feet (4.6 m) and  
water pressure at conditioner is not less than 40 psi  
(2.76 bar). You may elevate an additional 2 feet (61 cm)  
for each additional 10 psi (0.69 bar) water pressure.

4. Where the drain line is elevated but empties into a  
drain below the level of the control valve, form a  
7-inch (18-cm) loop at the far end of the line so that  
the bottom of the loop is level with the drain line  
connection. This will provide an adequate siphon trap.  
Overflow Fitting  
Installed  
Regenerant Tank  
5. Where the drain empties into an overhead sewer line,  
a sink-type trap must be used.  
IMPORTANT: Never insert drain line into a drain, sewer line  
or trap. Always allow an air gap between the drain line and  
the wastewater to prevent the possibility of sewage being  
back-siphoned into the conditioner.

Right Way  
Battery Back-Up  
The Performa ProSoft conditioner features a battery  
back-up feature that will allow the controller to continue to  
keep time and record water usage during a power outage.  
The control’s display will not light, but the controller will  
continue to measure water usage for up to five hours.  
When power is restored to the unit, it will continue to work  
as before. Connect a nine-volt alkaline battery to the  
connecting cable at the back of the conditioner’s control  
box, Figure 5.  
Figure 3  
Note: Standard commercial practices have been  
expressed here. Local codes may require changes to these  
suggestions.  
Regenerant Line Connection  
It will be necessary to install the regenerant line to the  
regenerant fitting on the valve (3/8-inch NPT).  
Be sure all fittings and connections are tight.  
Overflow Line Connection  
In the absence of a safety overflow and in the event of a  
malfunction, the REGENERANT TANK OVERFLOW will direct  
“overflow” to the drain instead of spilling on the floor  
where it could cause considerable damage. This fitting  
should be on the side of the cabinet or regenerant tank.  
To connect overflow, locate hole on side of regenerant  
tank. Insert overflow fitting (not supplied) into tank and  
tighten with plastic thumb nut and gasket as shown  
(Figure 4). Attach length of 1/2-inch (1.3-cm) I.D. tubing (not  
supplied) to fitting and run to drain. Do not elevate  
overflow line higher than 3 inches (7.6 cm) below bottom of  
overflow fitting. Do not tie into drain line of control unit.  
Overflow line must be a direct, separate line from overflow  
fitting to drain, sewer or tub. Allow an air gap as per drain  
line instructions (Figure 3).

Placing Conditioner into Operation  
After all previous steps have been completed, the unit is  
ready to be placed into operation. Follow these steps  
carefully.  
5. Place the conditioner into operation.  
A. With the water supply valve completely open,  
carefully advance the cycle indicator  
COUNTERCLOCKWISE to the center of the REFILL  
position. Hold at this position until water starts to  
flow through the regenerant line into the  
regenerant tank. Do not run for more than one or  
two minutes.  
1. Remove control valve cover by first depressing the  
plastic clips on the side of the cover. Pull front of cover  
up.  
Note: The following steps will require turning the  
cycle indicator (Figure 6) to various positions.  
Manually rotate the camshaft COUNTERCLOCKWISE  
only until cycle indicator points to desired position.  
(See manual regeneration sections for each control’s  
manual operation.)  
B. Advance the cycle indicator  
COUNTERCLOCKWISE until it points to the center  
of the REGENERANT/SLOW RINSE position.  
C. With the conditioner in this position, check to see if  
water is being drawn from the regenerant tank.  
The water level in the regenerant tank will recede  
very slowly. Observe water level for at least three  
minutes. If the water level does not recede, or if it  
goes up, reference the Troubleshooting section.  
2. Rotate cycle indicator COUNTERCLOCKWISE until it  
points directly to the word BACKWASH.  
3. Fill media tank with water.  
A. With water supply off, place the bypass valve(s)  
into the “service” position.  
D. Advance the cycle indicator  
COUNTERCLOCKWISE to the SERVICE position  
and run water from a nearby faucet until the water  
is clear and soft.  
B. Open water supply valve very slowly to  
approximately the 1/4 open position.  
IMPORTANT: If opened too rapidly or too far, media may  
be lost. In the 1/4 open position, you should hear air  
escaping slowly from the drain line.  
Electrical Connection  
100 VAC, 115 VAC, and 230 VAC units: Remove twist tie  
from the power cord and extend cord to its full length.  
Make sure power source matches the rating printed on the  
control. Be certain a wall switch does not control the  
outlet.  
C. When all of the air has been purged from the tank  
(water begins to flow steadily from the drain), open  
the main supply valve all the way.  
D. Allow water to run to drain until clear.  
E. Turn off water supply and let the unit stand for  
about five minutes. This will allow all trapped air to  
escape from the tank.  
12 VAC: Connect the plug of the transformer (supplied)  
secondary cable to the mating socket at the rear or  
bottom of the timer housing. Be certain the transformer is  
secure and is plugged into a power source of correct  
voltage that is not controlled by a wall switch.  
4. Add water to regenerant tank (initial fill).  
With a bucket or hose, add approximately 4 gallons  
(15 liters) of water to regenerant tank. If the tank has  
a salt platform above the bottom of the tank, add  
water until the level is approximately 1 inch (25 mm)  
above the platform.

Press the SET button and the far right number on the  
display starts flashing. 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. When you reach the far left digit, pressing the left  
arrow (←) button will return you to the far right digit.  
Programming  
This section covers all aspects of programming the control.  
The control is shipped from the factory with default values  
for Hardness and Capacity. These default values will result  
in a system capacity of 100 gallons (1 cubic meter). While  
the control will operate with these values, they should be  
changed to meet the actual operating conditions.  
Note: If you press and hold either the up arrow (↑) button  
or the down arrow (↓) button for more than one second,  
the flashing number will increment or decrement at the  
rate of 10 counts per second.  
Note that some parameters have a single unit of measure  
option such as the Rinse Time which is only entered in  
minutes. Other parameters have dual units such as Salt  
Amount which can be entered in pounds or kilograms. To  
select which units are active, look for a comment in the  
NOTES column of Table 1 and Table 3. It will reference  
another parameter that selects which units are active. For  
example, Parameter P12 (Table 3) selects U.S. units if it is  
set to “0” and metric if it is set to “1.”  
When the number is correct, press the left arrow (←)  
button. The first number stops flashing and the next  
number starts flashing. You can only change the flashing  
number. Continue changing numbers until you reach the  
desired setting. Press the SET button. The numbers stop  
flashing and the control accepts the new setting. After  
approximately 30 seconds, the control starts alternating  
the display between Time of Day and Capacity.  
Level I Parameters (Table 1)  
Note: If a beep sounds, the new setting is not accepted  
because it was outside the allowable range. The old value  
will be displayed.  
Level I Parameters are identified as those that have an LED  
indicator on the front panel. The green indicator  
illuminates next to the name of the active control setting.  
The end user has access to all of these parameters. In  
general, pressing the down arrow (↓) button displays the  
Level I Parameters in the following order:  
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 to enter the value.  
• Time of Day  
• Time of Regeneration  
• Hardness  
• Salt Amount  
• Capacity  
If you continue to press the down arrow (↓) button, the  
parameters start over with Time of Day. Pressing the up  
arrow (↑) button displays the parameters in reverse order.  
Refer to Table 1 for a description of these parameters and  
the available ranges for each parameter.

Time of Regeneration  
amount. The default value is 1.0 kilograin (0.1 kilogram). If  
this is not acceptable, press the SET button and enter a  
new value. Any value between 0.1 and 140 kilograins (.01  
and 14.00 kilograms) is allowed.  
The next value displayed is the Time of Regeneration. It  
has a default value of 2:00 a.m. If this is not acceptable,  
press the SET button and change the number. Press the  
SET button to enter the value. If 2:00 a.m. is acceptable,  
press the down arrow (↓) button.  
Note: If the calculation for the system capacity exceeds  
9999 gallons (99.99 cubic meters) (P5, Capacity, divided by  
P3, Hardness,) the control will display 9999 (99.99) 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.  
Hardness  
Hardness is the next value displayed. This value is the  
water hardness expressed in grains per gallon (milligrams  
per liter). The default value is 10 grains/gallon (100 mg/L).  
If this is not acceptable, press the SET button and enter a  
new value. Any value between 3 and 250 grains per gallon  
(30 and2500 milligrams per liter) is allowed. Press the SET  
button to enter the new value.  
At this time, all of the mandatory parameters are filled and  
the control is ready for operation. To further increase the  
efficiency of the system see P6 and P7 in the Level II  
Parameters Section. The display will alternate between the  
Time of Day and Capacity if no keys are pressed for  
30 seconds. The Capacity value is the volume remaining in  
gallons (cubic meters for metric) before a regeneration is  
needed.  
Salt Amount  
Salt Amount is the next value displayed. The default value  
for Salt Amount is 6 pounds (2.7 kilograms) of salt; refer to  
Table 2 for suggested salt settings.  
Verify proper power outage operation by briefly removing  
power to the control. The unit will beep and show the time  
of day when power is turned on.  
Note: This is the total amount of salt for a regeneration, not  
pounds per cubic foot. If 6 pounds is not acceptable, press  
the SET button and change the numbers. If 6 pounds is  
acceptable, press the down arrow (↓) button.  
If you wish to fine-tune the operation of this control, refer  
to Tables 1 and 3 for details concerning allowable values,  
defaults, and parameter descriptions. The programming  
procedure is the same for all of these parameters.  
Capacity  
Capacity is the next value displayed and is expressed in  
kilograins (kilograms). Refer to Table 2 for the capacity  
setting that corresponds to the resin bed volume and salt

Special Notes for Level II Parameters  
Level II Parameters (Table 3)  
The programming parameters in Level II can be used to  
increase the efficiency of this conditioner. Especially note  
the regenerant Draw Value parameter. This was set at the  
factory to meet the needs of a system with low water  
pressure. If an installation has higher water pressure or  
uses a large injector the efficiency of the system can be  
improved by changing P6 and P7.  
The Level II Parameters are P6 through P19 in Table 3. The  
Home Owner 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 (↑) buttons 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 shows the “P” number for that  
parameter. Refer to Table 3 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 1 and Table 3. When you reach  
P19, the next P number will go back to P1.  
Refill Control Value  
The Refill control valve must be set to 33. The valve is  
molded into the end of the refill control as shown in  
Figure 7. Verify that the setting is 33 and move on to the  
next parameter.  
When the parameter number you want to change is on the  
display, press the left arrow (←) button to display the data  
assigned to that parameter. Press the SET button and the  
far right number 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 a beep  
sounds, the new setting was not accepted. Refer to Table 3  
for allowable values for that parameter.  
Figure 7 - Refill Control  
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.

Regenerant Draw Value  
•
•
Parameter P18 allows the installer to lock the Salt  
Amount and Capacity values so they cannot be  
changed. When Parameter 18 is set to 1, those two  
settings can only be viewed when the control is in the  
Level II mode. The settings will be skipped when the  
control is in the Level I mode. When Parameter 18 is  
set to zero, the Salt Amount and Capacity can be  
viewed and changed in either Level I or Level II.  
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 4 for the correct value. Find the  
injector used in the Performa valve. The injector cap is  
labeled with the injector letter and 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 4. The control calculates  
the regenerant draw time using this value and the salt  
amount. The regenerant draw time is added to the Rinse  
Time (P10) to determine the total Regenerant Draw/Slow  
Rinse Time.  
Parameter P19 is used at the factory to enter default  
values. This parameter does not need to be changed.  
Changing this parameter will erase the values for all  
other parameters and replace them with default  
values.  
Manual Regeneration  
Electricity is used only to run the timer and to rotate the  
camshaft. All other functions are operated by water  
pressure. Therefore, in the event of a power outage, all  
regeneration positions may be dialed manually. Manual  
regeneration can be accomplished by removing the cover  
and turning the camshaft COUNTERCLOCKWISE to each  
regeneration cycle. Rotating the camshaft  
COUNTERCLOCKWISE by hand changes the cycles of  
operation. Each cycle position can be identified by viewing  
the cycle indicator on the front of the control. The following  
cycle times should be used for proper regeneration:

• 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.  
Do not exceed 10 minutes for the FAST RINSE/REFILL  
cycle as this will cause excessive salt usage during the  
next regeneration and possibly a salt residue in the  
softened water.  
• 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.  
Guest Cycle  
To force the control to perform a regeneration, press the  
REGEN button (Figure 6). This button is located on the front  
of the control. When you press the REGEN button, the  
control performs a full regeneration of the conditioner.  
• Parameter P15 has four allowable values. Values 0 or  
1 will cause the control to wait for Parameter P2, time  
of day of regeneration, to begin the regeneration.  
Values 2 or 3 will cause the control to start the  
regeneration as soon as the capacity is exhausted.  
If you press this button again more than one minute  
after regeneration begins, but before the regeneration  
is complete, a second regeneration will start when the  
first regeneration is finished. The display will freeze and  
only show the Regen Time Remaining as an indication that  
the second regeneration will be performed. When the first  
regeneration is complete, the second one will begin and  
the display will alternate between Time of Day and Regen  
Time Remaining.  
• When Parameter P15 selects a variable reserve type,  
0 or 2, Parameter P16 is used to calculate the initial  
seven average daily water usage values. The control  
multiplies the total capacity by the percentage  
entered for Parameter P16 and uses that value as the  
initial average daily usage for each day of the week  
until water usage establishes new averages.  
• Parameter 17 has several allowable values, however,  
many are reserved for future options and  
thus should not be used. Improper regenerations will  
occur if P17 is not set to 2.

Since a new installation has no history of water usage, the  
control multiplies the percent of capacity value set in  
Parameter P16 by the total system capacity to determine  
starting average for each day of the week. The factory set  
default value for P16 is 30 which means that 30% of the  
total system capacity is used for the starting average for  
each day.  
Automatic Regeneration  
There are two ways to have the control automatically start  
a regeneration: calendar override or having the control  
monitor the water usage.  
Calendar Override  
This feature is set in Parameter P14. It can be set for one to  
30 days. If it is set to zero, this feature is disabled. When  
this feature is active, the control keeps track of the number  
of days since the last regeneration and when that number  
equals the value set in P14, a regeneration is automatically  
started at the Time of Regeneration set in P2.  
Program Parameter P15 is also used to select whether the  
control waits until the Time of Regeneration set in  
Parameter P2 to start a regeneration, or if the control  
should begin a regeneration immediately when the  
capacity remaining is less than the reserve.  
Control Monitors the Water Usage  
The control compares the water usage to the calculated  
volume capacity of the system. The control uses the  
Capacity Parameter P5 divided by the Hardness  
Parameter P3 to calculate the volume capacity of the  
system. It also uses a reserve value to determine if a  
regeneration is necessary. If the water usage since the last  
regeneration is greater than the system capacity minus  
the reserve, a regeneration is needed.  
Note: If the water usage exceeds 150% of the system  
capacity between regenerations, the control will  
automatically call for a second regeneration the next day  
even if no water is used. This feature is included to make  
sure that an exhausted resin bed is completely recharged.  
Reserve Options  
There are two types of reserve options for this control:  
fixed reserve and historical water usage pattern. They are  
selected with Parameter P15.  
Fixed Reserve  
When the fixed reserve is selected, the control multiplies  
the maximum system capacity by the percent value set in  
Parameter P16 and uses the result as a reserve.  
Water Usage Pattern  
The other reserve option allows the control to adjust the  
reserve based upon the historical water usage pattern of  
the system. The control keeps track of the water usage for  
each day of the week and uses that day’s average usage  
multiplied by 1.2 as the reserve for that day. Every day at  
the Time of Regeneration, the control recalculates the  
day’s average water usage. If less than 10% of a day’s  
average water usage is used, the control will not change  
the day’s average. If more than twice the day’s average is  
used, the control uses the actual usage in the reserve  
calculation.

order. Refer to Table 5 for a description of these  
Figure 8  
This section covers all aspects of programming the  
Performa 960 FA control. The control is shipped from the  
factory with default values for most parameters. These  
default values will result in a system capacity of  
100 gallons (1 cubic meter). While the control may operate  
with these values, the following parameters must be  
changed to meet the actual operating conditions, and  
achieve maximum system capacity and efficiency:  
parameters and the available ranges for each parameter.  
Press the SET button and the far right digit of the display  
starts flashing. 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. When you reach the far left digit, pressing the LEFT  
ARROW (←) button will return you to the far right digit.  
• Time of Day  
• Time of Regeneration  
• Factor A  
Note: If you press and hold either the UP ARROW (↑)  
button or the DOWN ARROW (↓) button for more than one  
second, the flashing number will increment or decrement  
at the rate of 10 counts per second.  
• Regenerant Dosage  
• Capacity of the Unit  
• Refill Controller Value  
• Regenerant Draw Rate  
• Slow Rinse Time  
When the number is correct, press the LEFT ARROW (←)  
button. The far right digit stops flashing and the next digit  
to the left starts flashing. You can only change the  
flashing number. Continue changing numbers until you  
reach the desired setting. Press the SET button. The  
numbers stop flashing and the control accepts the new  
setting. After approximately 30 seconds, the control starts  
alternating the display between Time of Day and  
Capacity.  
Note that some parameters have a single unit of measure  
option such as the Slow Rinse Time which is only entered  
in minutes. Other parameters have dual units such as  
Regenerant Dosage which can be entered in gallons or  
liters. To select which units are active, look for a comment  
in the NOTES column of Table 5 and Table 7 on page 14. It  
will reference another parameter that selects which units  
are active. For example, parameter P12 (Table 8) selects  
U.S. units if it is set to “0” and metric if it is set to “1”.  
Note: If the new setting is not accepted because it was  
outside the allowable range, the old value will be  
displayed.

Time of Day  
Regenerant Dosage  
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.  
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.  
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.  
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.  
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.

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.

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.  
Refill Controller  
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 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.

Automatic Regeneration  
• Parameter P17 has been preset to 0. Do not change  
this setting. P17 must be set to 2 for Performa 960 FA  
operation.  
There are two ways to have the control automatically  
initiate a regeneration: calendar override or normal  
metered water usage.  
• Parameter P18 allows the installer to lock the  
Regenerant Dosage and Capacity values so they  
cannot be changed. When Parameter 18 is set to 1,  
those two settings can only be viewed when the  
control is in the Level II mode. The settings will be  
skipped when the control is in the Level I mode. When  
Parameter 18 is set to zero, the Regenerant Dosage  
and Capacity can be viewed and changed in either  
Level I or Level II.  
Calendar Override  
This feature is set in parameter P14. It can be set for 1 to  
30 days. If it is set to zero, this feature is disabled. When  
this feature is active, the control keeps track of the number  
of days since the last regeneration and when that number  
equals the value set in P14, a regeneration is automatically  
started at the Time of Regeneration set in P2.  
• Parameter P19 is used at the factory to enter default  
values. This parameter does not need to be changed.  
Using this parameter will erase the values for all other  
parameters and replace them with default values.  
Improper regenerations will occur if P19 is set to a 0 or  
3. P19 should be set on default number 99.  
Normal Metered Water Usage  
The control compares the water usage to the calculated  
volume capacity of the system.The control uses the  
Capacity parameter P5 divided by the Factor A parameter  
P3 to calculate the volume capacity of the system. It also  
uses a reserve value to determine if a regeneration is  
necessary. If the water usage since the last regeneration is  
greater than the system capacity minus the reserve, a  
regeneration is needed.  
Regeneration  
When the control begins a regeneration, the display will  
alternate between Time of Day and Regen Time  
Remaining. The Regen Time Remaining is shown in  
minutes. The control will start and stop an internal motor  
which drives the cam gear through the various  
regeneration positions. The control uses the information  
entered in the parameters shown in Table 8 to determine  
how long each part of the cycle should last.  
Note: If the water usage exceeds 150% of the system  
capacity between regenerations, the control will  
automatically call for a second regeneration the next day  
even if no water is used. This feature is included to make  
sure that an exhausted filter bed is completely recharged.  
Reserve Options  
If power fails during a regeneration cycle, the cycle  
completes normally when the power is restored.  
There are two types of reserve options for this control:  
fixed reserve and historical water usage pattern. They are  
selected with parameter P15.  
Note: The REGEN button is only active when the display is  
alternating between Time of Day and Capacity. When  
programming Level I or II parameters, the REGEN button is  
not active.  
Fixed Reserve  
When the fixed reserve is selected, the control multiplies  
the maximum system capacity by the percent value set in  
parameter P16 and uses the result as a reserve.  
The Regen Time Remaining in regeneration will continue to  
count down until the cam gear reaches the Service  
position.  
Manual Regeneration  
To initiate a manual regeneration, press the REGEN button.  
This button is located on the front of the control. When you  
press the REGEN button, the control performs a full  
regeneration of the conditioner.  
If you press this button again more than one minute after  
regeneration begins, but before the regeneration is  
complete, a second regeneration will start when the first  
regeneration is finished. The display will freeze and only

Water Usage Pattern  
Preventive Maintenance  
Injector Screen and Injector  
The other reserve option allows the control to adjust the  
reserve based upon the historical water usage pattern of  
the system. The control keeps track of the water usage for  
each day of the week and uses that day’s average usage  
multiplied by 1.2 as the reserve for that day. Every day at  
the Time of Regeneration, the control recalculates the  
day’s average water usage. If less than 10% of a day’s  
average water usage is used, the control will not change  
the day’s average. If more than twice the day’s average is  
used, the control uses the actual usage in the reserve  
calculation.

of regenerant pickup tube once a year or when sediment  
appears in the bottom of the regenerant tank.  
Clean injector screen and injector once a year:  
1. Unplug the wall-mount transformer.  
2. Shut off water supply or put bypass valve(s) into  
bypass position.  
3. Relieve system pressure by opening valve No. 7  
(at rear) with a screwdriver (Figure 9).  
Since a new installation has no history of water usage, the  
control multiplies the percent of capacity value set in  
parameter P16 by the total system capacity to determine  
starting average for each day of the week. The factory set  
default value for P16 is 30 which means that 30% of the  
total system capacity is used for the starting average for  
each day.  
4. Using a screwdriver, remove injector screen and  
injector cap (Figure 10).  
5. Clean screen using a fine brush. Flush until clean.  
6. Using a needle-nose pliers, pull injector straight out.  
7. Flush water into the injector screen recess of the valve  
body to flush debris out through the injector recess.  
Program parameter P15 is also used to select whether the  
control waits until the Time of Regeneration set in  
parameter P2 to start a regeneration, or if the control  
should begin a regeneration immediately when the  
capacity remaining is less than the reserve.  
8. Clean and flush the injector.  
9. Lubricate the O-rings on the injector, injector cap and  
injector screen with silicone lubricant only!  
10. Reinstall the injector, injector cap and injector screen.  
Removing the Valve Assembly for Servicing  
1. Unplug the power cord.  
IMPORTANT: Do not overtighten the plastic cap. Seat the  
cap lightly into position. Overtightening may cause  
breakage of the plastic cap that may not be immediately  
evident.  
2. Shut off water supply or put bypass valve(s) into  
bypass position.  
3. Remove cover and with screwdriver, relieve tank  
pressure by pushing open valve No. 7 (rear flapper) on  
control as shown (Figure 9).  
11. Plug the wall-mount transformer into outlet; reset  
clock if necessary.  
12. Slowly open water supply valve or return bypass  
valve(s) to the “service” position.

4. When used with a globe valve bypass, loosen and  
detach the inlet, outlet, regenerant and drain lines  
from the valve. If using the 1265 bypass, loosen and  
remove valve from bypass as well as loosening and  
removing the regenerant and drain lines.

Water Meter Maintenance  
The metering device used with the 960 demand controls  
may require simple maintenance. In rare instances, the  
turbine wheel of the water meter can collect small  
particles of oxidized iron, eventually preventing the wheel  
from turning.  
Tab  
1. Shut off the water supply or put the bypass valve(s) into  
the bypass position.  
2. Relieve pressure by opening the Backwash Drain  
Valve (the seventh back from the control) with a  
screwdriver (Figure 9).  
3. Loosen and remove the pipe/tube adapters or 1265  
bypass from the inlet and outlet of the valve body.  
Figure 11  
4. Using a needle-nose pliers, remove the turbine from  
the outlet housing. Grasp one of the four vanes of the  
outer gland and pull straight out to remove turbine  
assembly from the outlet of the valve (Figure 10).  
4. Relieve system pressure by opening the Backwash  
Drain Valve (the seventh valve back from the control)  
with a screwdriver, Figure 12.  
5. Carefully remove the turbine wheel from the housing.  
Use a toothbrush to lightly scrub the iron off the  
magnet. Iron buildup on the surfaces can be removed  
by soaking the wheel in a mild sodium hydrosulfite  
(such as RoVer*) solution for a few minutes. Flush  
thoroughly with water.  
*RoVer is a trademark of Hach Chemical Company.  
6. Carefully reinstall the turbine wheel into the turbine  
cage housing. Make sure that the shaft of the wheel  
seats into the bearing of the cage. Reassemble the  
turbine cage and check that the wheel rotates freely.  
Figure 12  
7. Reinstall the turbine cage into the outlet of the valve.  
5. To remove the camshaft or to reinstall it, the arrow on  
the rear of the cam shaft must be pointing at the line  
on the rear “hoop” of the top plate. This occurs when  
the cycle indicator is rotated to the refill position. Press  
down on the back of the camshaft to disengage it  
from the rear “hoop” of the top plate, Figure 13.  
Slide the camshaft back to disengage it from the timer,  
Figure 14.  
8. Reinstall the pipe/tube adapters or 1265 bypass to the  
inlet and outlet of the valve.  
9. Turn on the water supply or put the bypass valve(s)  
into the service position and purge the air out of the  
system.  
To check for proper meter operation, open a downstream  
faucet and observe the water flow indication, blinking  
colon, on the control display.  
Removing the Control  
Complete the following steps to remove the 960 ProSoft  
control for servicing:  
1. Unplug the wall-mount transformer.  
2. Shut off the water supply or put the bypass valve(s)  
into bypass position.  
3. Remove the rear cover by depressing the two tabs  
provided on the cover, Figure 11. Lift the front of the  
cover and remove to expose the valve body.

Figure 14  
6. Disconnect the turbine probe from the turbine  
assembly.  
7. Lift the control off the valve, Figure 15. To replace the  
control, reverse the above procedure. Note that the  
camshaft needs to be positioned correctly before it  
can be inserted into the back of the control. There is a  
locating arrow on the camshaft. Position the arrow on  
the top of the shaft and slide the camshaft into the  
control. Push up on the end of the camshaft, furthest  
from the timer, snapping it into place.

Troubleshooting  
The technology upon which the Autotrol Performa control  
valve is based is well established and proven in service  
over many years. However, should a problem or question  
arise regarding the operation of the system, the control  
can very easily be serviced. For parts mentioned, refer to  
exploded views in the Replacement Parts section of this  
manual.  
IMPORTANT: Service procedures that require the water  
pressure to be removed from the system are marked with  
a ! after the possible cause. To remove water pressure  
from the system, put the bypass valve or three-valve  
bypass into the bypass position and open the backwash  
drain valve (the seventh valve back from the control) with  
a screwdriver. Restore system water pressure when the  
service work is completed.

Disinfection of Water Conditioners  
The materials of construction of the modern water  
conditioner will not support bacterial growth, nor will these  
materials contaminate a water supply. However, the  
normal conditions existing during shipping, storage and  
installation indicate the advisability of disinfecting a  
conditioner after installation, before the conditioner is  
used to treat potable water. In addition, during normal use,  
a conditioner may become fouled with organic matter or  
in some cases with bacteria from the water supply.  
2. Regenerant tank conditioners  
A. Backwash the conditioner and add the required  
amount of hypochlorite solution to the regenerant  
well of the regenerant tank. (The regenerant tank  
should have water in it to permit the solution to be  
carried into the conditioner.)  
B. Proceed with the normal regeneration.  
Calcium Hypochlorite  
Thus every conditioner should be disinfected after  
installation, some will require periodic disinfection during  
their normal life, and in a few cases disinfection with every  
regeneration would be recommended.  
Calcium hypochlorite, 70% available chlorine, is available  
in several forms including tablets and granules. These solid  
materials may be used directly without dissolving before  
use.  
Depending upon the conditions of use, the style of  
conditioner, the type of ion exchanger, and the disinfectant  
available, a choice can be made among the following  
methods.  
1. Dosage  
A. Two grains (approximately 0.1 ounce) per cubic  
foot.  
2. Regenerant tank conditioners  
Sodium or Calcium Hypochlorite  
A. Backwash the conditioner and add the required  
amount of hypochlorite to the regenerant well of  
the regenerant tank. (The regenerant tank should  
have water in it to permit the chlorine solution to  
be carried into the conditioner.)  
Application  
These materials are satisfactory for use with polystyrene  
resins, synthetic gel zeolite, greensand and bentonites.  
5.25% Sodium Hypochlorite  
B. Proceed with the normal regeneration.  
These solutions are available under trade names such as  
Clorox Bleach*. If stronger solutions are used, such as  
those sold for commercial laundries, adjust the dosage  
accordingly.  
1. Dosage  
A. Polystyrene resin: 1.2 fluid ounces per cubic foot.  
B. Non-resinous exchangers: 0.8 fluid ounce per  
cubic foot.
