The Autotrol 460TC is a complete replacement timer assembly designed for 440 series water treatment systems. This electronic 7-day programmed timer operates at 60 Hz and includes a 12-volt AC transformer. It is engineered to replace previous 440, 440i, and 1040778 Timer Assemblies, ensuring compatibility with a range of Autotrol valves including older 150, 155, 160, 163, 168 series, and newer 255, 263, and 268 series valves that currently utilize 440, 440i, 440iHV, or 460i timers. The 460TC allows for precise control over regeneration cycles, enabling users to set specific days for automatic regeneration.

The 460TC timer assembly features an electronic display and buttons for setting the time of day and regeneration schedule. Programming instructions are crucial for optimal performance.

3.1 Programming the 460TC

The following image provides a detailed diagram and instructions for programming the unit:

3.2 Fametrahana famantaranandro

• Move the jumper to the set of pins next to the word CLOCK (refer to Figure 4, Figure 8 in the diagram).
• Tsindrio ny BLACK TIME SET button until the desired clock setting is displayed. The clock range is 0 to 1. Select 0 for standard AM/PM clock or 1 for 24-hour clock.

3.3 Time of Day Setting

• Move the jumper to the set of pins next to the word Time (refer to Figure 4, Figure 5 in the diagram).
• Tsindrio ny BLACK TIME SET button until the desired time of day is displayed. The closest hour is indicated by a light next to the letters PM on the display window.
• Fanamarihana: The unit is factory set to regenerate at 2:00 A.M. If you need 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).
• Fanamarihana: The Timer Locking Pin should always be horizontal (Figure 5 in the diagram) during operation.

3.4 Days Setting (Regeneration Frequency)

• Move the jumper to the set of pins next to the word ANDRO (refer to Figure 4, Figure 6 in the diagram).
• Tsindrio ny BLACK TIME SET button until the desired number of days between regeneration is displayed. The range is from 1 to 99 days, with every 3rd day as the default.

The Autotrol 460TC timer assembly is designed for minimal maintenance. Regular checks can help ensure its longevity and proper function.

• Fanadiovana: Periodically wipe the exterior of the timer assembly with a soft, damp lamba hanalana vovoka sy loto. Fadio ny mampiasa akora simika mahery vaika na mpanadio abrasive.
• Fifandraisana elektrika: Ensure the transformer connection remains secure and free from damage. Do not expose the unit to excessive moisture.
• fitazonana fahatsiarovana: The 460TC features Nonvolatile Random-Access Memory (NOVRAM) to retain programming data during power outages. This memory stores the time of day, number of days between regenerations, and the number of regenerations since the last reset. If a power outage occurs, the NOVRAM will restore the data to the microprocessor. However, if the outage is prolonged (months or years), or if the unit displays a blank screen, reprogramming may be necessary.

If you encounter issues with your 460TC timer assembly, consider the following common troubleshooting steps:

• Unit Not Powering On / Blank Display:
  • Check the power outlet to ensure it is functional.
  • Verify that the 12-volt AC transformer is securely connected to both the timer assembly and the power outlet.
  • If the display remains blank after a prolonged power outage, reprogramming may be required.
• Incorrect Time or Regeneration Schedule:
  • Refer to Section 3, "Operating and Programming," to re-program the clock, time of day, and regeneration days.
  • Ensure the jumpers are correctly positioned for the desired setting (CLOCK, TIME, or DAYS).
• Regeneration Not Occurring:
  • Verify that the regeneration days are set correctly.
  • Check the water pressure and ensure the system is not bypassed.
  • Ensure the timer locking pin is horizontal during operation.
• Physical Installation Issues:
  • If the unit feels loose or is not engaging properly, re-check the locking pin and ensure the assembly is fully seated on the valve shaft.
  • Confirm that the valve trigger is correctly positioned as described in the installation section.
