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 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.
•
This control does not use Parameter P8. No entry is
needed for this parameter.
•
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 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.
•
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.
•
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 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:
BACKWASH
—14 minutes
Regenerant/SLOW RINSE
—52 minutes
FAST RINSE/REFILL
—10 minutes
PURGE
—6 minutes
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.
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.
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.
