Refill Control
Each Technetic Plus control valve is supplied with a
refill/backwash control based on the water conditioner
system size. To verify that the correct control is installed,
check the number located on the face of the refill/backwash
control, Figure 12. This number should match the diameter of
the resin tank. To operate correctly, the control must have
parameter P6 programmed to the correct refill controller
value. The default value in P6 is 33. Find the correct value in
Table 4. If 33 is not correct, press the SET button and enter
the correct value from Table 4.
Note: 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.

Brine Draw Value
Brine draw value P7 is used by the control to calculate the
brine draw time. The brine draw value is an estimate of the
flow rate of brine through the injector. This value varies with
injector size and conditioner system size. The default value in
P7 is 25. Refer to Table 4 and find the correct brine draw
value for your conditioner system. Press the SET button and
enter a new brine draw value from Table 4.
• The 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, which is based
on conditioner system size. The default value for P10 is 40
minutes. Refer to Table 4 to find the correct slow rinse time
for your conditioner system. Press the SET button and enter
a new value for P10.
• 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, page
16 for more information on the calendar override feature.
• Parameter P15 selects a variable reserve type, 0 to 3. For
more information on reserve options, refer to Page 17.
• Parameter P16 is used to calculate the initial 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. The default is set for 30% of the capacity. In
most installations this is acceptable.
• Parameter P17 has been preset to 1. Do not change this
setting. P17 must be set to 1 for 1100 operation.
Improper regenerations will occur if P17 is set to 0.
• 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.
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 9.
