AUTOTROL
460i and 460TC Control System Installation and Operation Instructions
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 the
regeneration positions may be dialed manually by pressing
the pointer knob with a straight-blade screwdriver and turning
COUNTERCLOCKWISE.
• Backwash...14 minutes
• Brine and slow rinse...52 minutes
• Brine refill...10 minutes
• Fast rinse/refill...6 minutes
Do not exceed 10 minutes for the refill cycle as this will cause
excessive salt usage during the next regeneration and possibly
a salt residue in the conditioned water.
DO NOT advance the pointer knob directly to the conditioned
water position (6 o’clock) when manually advancing the
camshaft after a manual regeneration or when servicing the
conditioner. Advance it to just past the fast rinse position,
approximately 7 o’clock. The timer will then advance itself to
the conditioned water position where the internal switch will
turn the motor off. The internal switch will not be operated
and the motor will continue to run if advanced directly to the
conditioned water position.
If power fails during a conditioner regeneration, the cycle will
be completed normally when the power is restored.
PROGRAMMING THE 460TC
Plug the wall-mount transformer into a functioning electrical
outlet that is not controlled by a switch. Plug the transformer
into the transformer plug receptacle on the control.
Open the access door by pushing the raised tab on the door
toward the left while pulling the tab out (Figure 5).

Time of Day Setting
With the jumper on the set of pins next to the word
TIME
(Figure 6), set the time of day to the closest hour by pressing
the black
TIME SET
button. PM hours are indicated by a light
next to the letters
PM
on the display window.
NOTE:
The use of a small needle-nose pliers will aid in
moving the jumper.
NOTE:
The unit is factory set to regenerate at 2:00 a.m. If
you prefer to have the unit regenerate at an earlier
or later time, simply set the current time of day
accordingly (e.g., to have the unit regenerate at 4:00
a.m.—two hours later—set the clock two hours
earlier than the actual time of day).
NOTE:
The Timer Locking Pin should always be horizontal
(Figure 5) during operation.
Days Setting
Move the jumper to the set of pins next to the word
DAYS
(Figure 7). Press the black
TIME SET
button until the desired
number of days between regeneration is displayed. The range
is from 1 to 30 days.

Clock Setting
Move the jumper to the set of pins next to the word
CLOCK
(Figure 8). Press the black
TIME SET
button until the desired
clock setting is displayed. The clock range is 0 to 1. Select 0
for the standard AM/PM clock or select 1 for a 24 hour clock.
Return the jumper to the top set of pins next to the word
TIME
and replace the access door. The jumper must NOT be left
on any pins other than the top pair next to the word
TIME
.
Otherwise, the unit may show a blank display.
NOTE:
A spare jumper is located on the bottom set of pins.
Memory Retention
During a power outage, all of the data in the microprocessor’s
memory is stored in a special electronic chip called NOVRAM,
Nonvolatile Random Access Memory. This data includes the
time of day, water usage amounts, and the number of days
since the last regeneration. The NOVRAM will maintain the
data in its memory. When power is restored, the NOVRAM
returns the data to the microprocessor and operation resumes
as if an outage never occurred.
The time of day will be late by the length of the power
outage. Most power outages are less than one minute in
duration. Therefore, it may be months or years before the
time display would require resetting. If an outage of one or
more hours occurs, the time of day should be reset. No other
reprogramming is necessary.
